I have installed the drivers for CPU and motherboard

I miss the driver for the GPU in this list. Yes, i know that the GPU is part of this APU, nevertheless it needs drivers.

and the CPU cooler squeak and have a jerky motion,

Any chance to monitor that CPU/GPU? If i get this correct, overheating could be a problem.

You need to have or OC your system RAM at 2133MHz to have full bandwidth for "video memory" and try with this parameters in shortcut -cpuCount=2 -exThreads=3 -maxMem=2047 -maxVRAM=2047

With the unfair advantage of giving DDR3 2133MHz RAM only to the Richland APU here are the following results:

F1 2012

Richland 53.3 FPS

Trinity 39.9 FPS

Richland +33.6%

Skyrim

Richland 40.9 FPS

Trinity 36 FPS

Richland +13.6%

Tomb Raider

Richland 40.5 FPS

Trinity 35.1 FPS

Richland +15.4%

Metro: Last Light

Richland 36.1 FPS

Trinity 30.6 FPS

Richland +18%

Richland Average Performance Increase: +20.1%

Compare ArmA2OA.cfg files from both computers and look for this 2 lines

localVRAM=xxxxxxxx;

nonlocalVRAM=xxxxxxxx;

Read this carefully

localVRAM= GPU RAM size in bytes

nonlocalVRAM= Shared Memory size in bytes..this info you can find when run dxdiag tool

I saw these values in dxdiag tool

Computer 1 (Arma 2 run correctly)

localVRAM= GPU RAM = 1995 MB (GPU = AMD Radeon HD 7480D integrated in AMD A4 APU) in specification of AMD Radeon HD 7480D appear no memory: she uses memory from nonlocal memory ?

nonlocalVRAM = 4096 mb

Computer 2 (Arma 2 run incorrectly)

localVRAM= GPU RAM = 82 MB: why is it so small ? (GPU = AMD Radeon HD 8670D integrated in AMD A10 APU): in specification of AMD Radeon HD 8670D appear no memory: she uses memory from nonlocal memory ?

nonlocalVRAM = 8192 mb

please tell me what can I do ? Why Crysis can running correctly?

You have old problem/bug :(

You can try to run game with last beta patch and -maxVRAM=2047 parameter in shortcut or ( I think you don't like this fix ) take out 4GB system RAM and try.
