Does Arma 3 use a lot of RAM?

ArmA is a 32-bit-application and uses only around 3 GB of RAM, but your computer may do some other jobs while you’re playing, so a bit more than 4 GB of RAM may make sense. But don’t expect any miracles.

How much RAM do I need for Arma 3?

SYSTEM REQUIREMENTS

MINIMUM
DirectX®	10
RAM	4 GB
HARD DRIVE	45 GB free space
AUDIO	DirectX® compatible on-board

Is 8gb RAM enough for Arma 3?

Technically, that is the absolute minimum hardware to run Arma III. While the game will load and function, you will not like the experience. With only 8 GB or RAM the only time (if even then) you will see 60 FPS or better is when you are on foot.

How do I commit more RAM?

1. Allocate RAM Using Windows Task Manager

On your Windows 10 PC, open the Windows Task Manager app. To do so, use your keyboard’s CTRL + SHIFT + ESC buttons.
Go to the “Details Tab.”
Right-click on the application you wish to assign extra RAM to and select priority.

Can a GTX 1650 run Arma 3?

A laptop based on “an i5-9300h and a GTX 1650 with 8gb RAM and a SSD” will allow your mate to play Arma3. Arma3 is still “CPU dependent”, it means that first of all, you must try to get the fastest/efficient CPU you can allow.

Do you need a powerful PC for Arma 3?

Processor: Intel Core i5 or AMD Athlon Phenom X4 or faster. Memory: 2 GB. Video card: Nvidia Geforce GTX 260 or ATI Radeon HD 5770 with Shader Model 3 and 896 MB VRAM, or faster. DVD: Dual Layer compatible.

Should I enable hyperthreading Arma 3?

If your computer is primarily used for Arma, you should disable hyper-threading in the Bios. Another added benefit is a cooler running computer because hyper-threading creates more heat.

Is Arma 4 coming out?

Czech developer Bohemia Interactive’s Armed Assault series – long since officially simplified to the infinitely catchier ‘Arma’ – has for some time been generally recognised as the best multiplayer military simulation (mil-sim) shooter there is. And, on May 17, 2022, Bohemia finally announced Arma 4 was coming.

Is Arma 3 a demanding game?

Its not ‘graphically’ demanding. It is limited by how fast your CPU can run 1 thread. So if you have a low clock, low Instructions Per Clock/Tick CPU your performance will suffer far more.

How many GB is arma2?

Hard Drive: 10 GB free HDD space.

Why does Arma 3 lag so much?

The reason behind this is simply the fact that a wireless internet connection is prone to packet loss and disconnections by design which is why it is not suitable for gaming at all. If you are looking to fix Arma 3 Lag for good, you should switch to a wired internet connection immediately.

Does Arma 3 use multiple cores?

I was wondering is there any way to make Arma 3 use all 8 cores and 16 threads on the processor? Arma 3 is multithreaded, albeit not as well as it ought to be. You can set the game to use all your cores through the relevant options in the Launcher. Be warned, that Ryzen will not be used to its full potential.

Should I enable hyperthreading Arma 3?

If your computer is primarily used for Arma, you should disable hyper-threading in the Bios. Another added benefit is a cooler running computer because hyper-threading creates more heat.

What does malloc system do?

The malloc subsystem manages a logical memory object called a heap. The heap is a region of memory that resides in the application’s address space between the last byte of data allocated by the compiler and the end of the data region.

Requirements

SOFTWARE REQUIREMENTS

The following software packages need to be installed on your computer before running Arma 3 (these packages are normally installed by the Steam client when running Arma 3 for the first time).

Microsoft .NET Framework 4.5.2 download from here

Microsoft Visual C++ Runtime 2010 x86* download from here

Microsoft Visual C++ Redistributable for Visual Studio 2013 (x86 – vcredist_x86.exe)* download from here

*Note: You have to install the x86 version of the package even when you have a 64-bit system.

Arma 3: Custom Memory Allocator

This page is about Arma 3 functionality. For similar functionality in Arma 2, see Arma 2: Custom Memory Allocator

The memory allocator is a very important component, which significantly affects both performance an stability of the game. The purpose of is to allow the allocator to be developed independently on the application, allowing both Bohemia Interactive and community to fix bugs and improve performance without having to modify the core game files.

Default

Default allocator used by the engine is based on Intel TBB 4 (see details about tbb4malloc_bi below)

Specifying a custom allocator

The allocator is a dll placed in a directory named “dll” located next to the game executable. Allocator search order is:

If no allocator dll is found, functions _aligned_malloc/ _aligned_free (using Windows Heap functions) are used as a fallback note: Windows 7 allocator seems to be quite good, and it may therefore make sense for some users to delete all custom allocators on Windows 7 or newer).

You can select an allocator by via commandline below or deleting other allocators from the \dll\ folder.

Commandline parameter

You can specify a particular allocator from a command line, like:

-malloc=tbb4malloc_bi

-malloc=jemalloc_bi

or

-malloc=mybestmalloc_bi

-malloc=system can be used to force using Windows allocator even when allocator dlls are present

ⓘ Dll directory and extension are appended automatically, the allocator must not be located in other directory and its name must not contain any dots before the .dll extension.

To enable allocator to use Large Pages instead of Small Pages start game with commandline switch -hugepages

Dedicated server

You can specify allocator for Windows dedicated server the same way as for client binary,

with specifically adjusted memory allocator you may experience performance gains,

for example with Large Pages support or ability define huge pre-allocation memory regions to lessen allocation load.

Linux dedicated server uses allocator provided by operating system. There are NO plans to allow its customization yet.

DLL Interface

The dll interface is as follows:

extern “C” { __declspec ( dllexport ) size_t __stdcall MemTotalCommitted (); // _MemTotalCommitted@0 on x86 __declspec ( dllexport ) size_t __stdcall MemTotalReserved (); // _MemTotalReserved@0 on x86 __declspec ( dllexport ) size_t __stdcall MemFlushCache ( size_t size ); // _MemFlushCache@4 on x86 __declspec ( dllexport ) void __stdcall MemFlushCacheAll (); // _MemFlushCacheAll@0 on x86 __declspec ( dllexport ) size_t __stdcall MemSize ( void * mem ); // _MemSize@4 on x86 __declspec ( dllexport ) void * __stdcall MemAlloc ( size_t size ); // _MemAlloc@4 on x86 __declspec ( dllexport ) void __stdcall MemFree ( void * mem ); // _MemFree@4 on x86 __declspec ( dllexport ) size_t __stdcall MemSizeA ( void * mem , size_t aligment ); // _MemSizeA@8 on x86 __declspec ( dllexport ) void * __stdcall MemAllocA ( size_t size , size_t aligment ); // _MemAllocA@8 on x86 __declspec ( dllexport ) void __stdcall MemFreeA ( void * mem ); // _MemFreeA@4 on x86 __declspec ( dllexport ) void __stdcall EnableHugePages (); // _EnableHugePages@0 on x86 };

Note: besides of the interface above, if the allocator is performing any per-thread caching, it will typically want to perform a cleanup of per-thread data on DLL_THREAD_DETACH event sent to DllMain function.

MemTotalCommitted()

Total memory committed by the allocator (should correspond to VirtualAlloc with MEM_COMMIT)

MemTotalReserved()

Total memory reserved by the allocator (should correspond to VirtualAlloc with MEM_RESERVE)

MemFlushCache(size_t size)

Try to flush at least “size” bytes of memory from caches and working areas, return how much memory was flushed. Called by game when memory needs to be trimmed to reduce virtual memory use.

MemFlushCacheAll()

Flush all memory held in caches and working areas. Called by game when memory needs to be trimmed to reduce virtual memory use.

MemSize(void *mem)

Return allocated size of given memory block.

MemAlloc(size_t size)

Allocate at least size bytes of memory, return the allocated memory. If the size is 16 B or more, the memory must be 16 B -aligned, so that it is usable to hold SSE data.

MemFree(void *mem)

Free given memory block.

MemSizeA(void *mem, size_t alignment)

Return allocated size of given memory block allocated via MemAllocA. Aligment must be the same as when MemAllocA was called.

MemAllocA(size_t size, size_t alignment)

Allocate at least size bytes of memory, return the allocated memory aligned to “aligment” bytes.

MemFreeA(void *mem)

Free a given memory block allocated via MemAllocA.

EnableHugePages()

Called before the first allocation to enable Huge/Large Pages. Implementing this function is optional.

Observed Behaviour

API Usage

ⓘ The following information is based on various tests that should reflect how Arma 3 actually uses the memory allocator.

MemTotalCommitted() and MemFlushCache(size_t size) are called dozens of times per second, almost every frame. They should return as soon as possible to avoid blocking the caller thread. Avoid putting extra stuff (especially mutex) and be careful about the performance! However, they seem not to affect game’s behaviour at all, returning 0 would be okay even on the long run.

MemTotalReserved() is apparently never called.

MemFlushCacheAll() is apparently only called when the game finished loading and is about to show the main rendering window.

MemAlloc(size_t size) and MemAllocA(size_t size, size_t alignment) are called when the game needs more memory space. Once they are called, a corresponding MemSize(void *mem) or MemSizeA(void *mem, size_t alignment) would be called to ensure it gets the memory it needs. If not, the game would repeat the procedure until it gets all it wants. When the procedure executes, it is likely that Arma 3 is loading things into memory (starting a mission, spawning various new entities, etc). They should be performance critical too, or it may cause freezes when the game allocates new memory blocks.

⚠ Ideally, no mutex or lock should be used in any of these API but for debug purpose.

Server and Client

The Arma 3 client rarely takes more than 8GB of active physical memory, while a server rarely takes more than 2GB. If reserved huge pages are implement in CMA, these values may be used as references.

« Arma has multiple internal allocators. The pool allocator used for all of scripting does not respect large pages flag, but these don’t allocate that often. » – source) » – Dedmen

These aspects would not take advantage of a Custom Memory Allocator.

A Dedicated server may not take advantage of custom allocator as well, as the total page size allocated by server is always equal to reserved huge pages size + active physical memory , which means it does not allocate through CMA at all.

How to Allocate More RAM to a Program

RAM (Random access memory) is one of the biggest contributing factors to a computer’s performance. Without sufficient RAM, applications or programs don’t work as intended, perform slower, and can even crash in the middle of your work if the available memory is critically low. A good practice is to allocate more RAM to a program. To know more about ram allocation, follow through the next sections.

For the best performance, not only you should have a sufficient amount of RAM installed on your pc, but also you may need to cut down memory consumption to other background apps and allocate those extra RAM to your application in need. In this article, we’re going to discuss the different ways on how to allocate more RAM to a program, to have improved performance if needed.

How to Allocate More RAM to a Program or a Game?

There are many ways to do memory allocation. You can either control and limit the memory consumption of background applications or set your current program as a priority in the execution method. You can also check the RAM of your operating system. If any issues are there, you can scan with Windows Memory Diagnostic Tool.

As long as you have sufficient free memory available for a program to run, you don’t necessarily need to allocate more RAM to it, but often the case is different where you may fall short of RAM. If however, you’re facing RAM issues throughout the whole system, you can optimize RAM to your best fit of memory usage. Follow these simple steps to ensure a better performance to allocate ram to a program.

Set a Higher Priority of Specific Apps

While running an application, you can head over to the task manager and set the priority of the app to high or low. Although performance greatly depends on the RAM speed, this comes very handy while multitasking. For example, while you use the browser to download something, it takes much of your available RAM. You can set it to a lower priority, and do other tasks seamlessly like playing games without encountering lags.

To set priority, you have to run the application first. Then, minimize it, and go to the Task Manager by right-clicking on the taskbar, or search in the Windows search box, or even pressing Ctrl + Shift + Esc at the same time. You can check the ram usage of a specific program there.

From the task manager, choose the target application from the Processes tab.

tab. Right-click on the app and choose Go to details.

From the Details tab, choose the app, right-click, and select Set Priority.

tab, choose the app, right-click, and select Set the priority of the application to high or real-time if you want more memory to be allocated.

Set a lower priority if you want less RAM expense for the task.

Keep in mind that, setting priority isn’t a one-time process. You will have to do it every time you launch the app and need more RAM allocation. Alternatively, if your CPU is at max usage, you can assign more cores of CPU to an application by choosing Set Affinity and selecting CPU cores. Select only CPU 0 if you want to focus on other apps, or select all for best performance to dedicate ram so that the application can use more ram.

Finding the Memory Reserve Settings in Apps

How to allocate more ram to an app? There are much software, specially design and rendering software, which comes with their very own settings to control how much RAM is reserved or allocated ram for the application. For example, many Adobe applications like the Adobe Premiere Pro come with these settings. Go to the Edit tab. Here, go to Preferences > General > Memory and set the amount of RAM in Ram reserved for other applications.

If you want the best performance, set this to low. If you want to multitask, set a higher memory reserve. These settings can be found on different labels in many software, which you can use.

Disabling Background Applications

If you’re not multitasking, yet you find a low amount of free RAM, chances are your background applications are eating up a significant amount of memory. You should turn these background apps off for better overall performance at the cost of occasional slower launching time or indexing.

You can easily disable background applications by searching for Background apps in the Windows search bar. Here you can choose which apps can run in the background, or turn off Let apps run in the background option altogether. You can also pick unwanted apps from the task manager, right-click on them and disable them too.

Disabling Unwanted Services to Get more Additional RAM

There are plenty of services running on your computer that started when you installed an app, or for other conveniences, but ate up your memory in the process. You can disable the unnecessary services to have performance improvements with the system configuration feature. Just keep in mind not to disable services that are necessary for any important apps to run.

To do this and get additional memory,

Press Windows key + R to launch Run prompt.

to launch Run prompt. Type MSConfig and hit enter.

Go to the Services tab, where you can find all the running services.

tab, where you can find all the running services. Check Hide all Microsoft services on the bottom, so that you can’t accidentally disable any essential services.

Uncheck any unnecessary services from the left side box. You can also select Disable all but this isn’t recommended.

but this isn’t recommended. Click on Apply, and OK.

Restart your computer.

By clearing up your running services, you can save a lot of memory which can be used to run important programs without lags.

Increase Virtual Memory for Better Memory Management

Virtual Memory or page file memory allows the computer to compensate for the physical memory shortage. It temporarily transfers the data from ram to disc storage to increase ram memory. Let’s take a look at how to increase the page file size or the VRAM.

Step-1: Go to “Control Panel” and then find out “System”. From the system go to “Advanced system settings”.

Step-2: Now, under the “Performance” tab, you will find out “Settings”.

Step-3: Next select the “Advanced” tab. There select “Programs”. Click on “Change” from there.

Step-4: From the appeared “Virtual Memory” window, deselect “Automatically manage paging size”. Now, select the C drive.

Step-5: Now, select the “Custom size” and you can set there the initial and maximum virtual memory size. Under the total paging file size for all drivers, you will see a recommended memory size in MB. Set it as the initial memory.

Step-6: To set the maximum memory size, you have to calculate it in MB. But remember, you can not set it over 1.5 times the physical RAM size to increase memory on the computer. For example, for 8 GB RAM, the virtual memory can be 12 GB. Now click on “Set” and then hit “Ok”.

Step-7: Click on “Apply”, “Ok” and “Ok”. At last, restart the pc and the virtual memory will be sent successfully to increase computer ram.

Buying or Upgrading RAM to Add More Memory

This is the last yet the most effective way to have more RAM for programs and increase computer memory. If your physical memory itself is very low, like 4GB for example, you should invest in buying new memory modules if you have extra slots on your motherboard.

Or you can replace the existing memory stick with a higher memory module if all slots are filled. If the RAM is already low, no performance tweaks will improve performance significantly. Fortunately, memory sticks are pretty inexpensive, and a good investment almost always. However, don’t follow hoaxes like downloading RAM online, which is a waste.

How to Allocate more CPU Power to a Program?

First, go to the task manager as discussed earlier. You can also use “Ctrl+Shift+Esc” as a keyboard shortcut for that. Under the “Processes” tab, right-click on the particular program. Now, from the pop-up window press on “Set Affinity”. That’s it.

Can you dedicate Ram to Graphics or Video RAM?

You can increase the graphics card video memory from Registry Editor. The system automatically adjusts this depending on the application is run. More RAM to the onboard graphics adapter means better performance of the video chipset. But this can decrease the system RAM available to the processor.

Frequently Asked Questions (FAQs) on Allocating RAM

Ans: In some cases, the answer is yes, if you have a low amount of RAM.

What happens if I allocate too much virtual RAM in the ram allocation process?

Ans: If the OS uses the extra page file, you experience lags while working.

Conclusion

In this article, we’ve discussed how to allocate more RAM to a program. You can apply these easy steps in Windows 10, 8, or 7. Allocating more RAM can help a lot for a smoother performance or while multitasking. These are also completely safe methods for your computer. Check these out if you’ve got sufficient memory yet facing problems on running a program within the available memory. If you are a gamer, then you can improve your gaming performance by using the Windows registry. After reading the whole article, now we hope that know about how to allow a program to use more ram.
