Hello there, I am an old member of MPGH, stalking this page for yearsand trying to help people in case of having trouble with optimizing their game. In this thread I would like to help you guys in tweaking you CoD:AW. I have experienced some trouble with this game, I was able to play with ~20 FPS before modificating, right now I am playing at 60-80 FPS on the 1920x1080 resolution.
What to turn on/off to increase the performance?
Resolution - Most important setting for your optics, try to put it your original computer resolution.
Display mode - Fullscreen-Mode increases the performance a bit, being in the window-mode splits the concentration of your CPU on other processes
Sync Every Frame (VSync) - SLI-owners and high-performance freaks shall turn it off, it freezes your amount of FPS on 60.
FOV - rendering distance, the lower you set it, the less VRAM the game takes.
Render resolution - You can lower it to increase the performance, the textures will look kinda blurred, in case of having an old PC, you have to take it in buy.
Texture quality - set it on high when having the Anisotropic Filtering, putting it on extra will eat alot of your VideoRAM. You can manually try to regulate it.
Texture/ Normal Map/Specular Map Resolution - It's up to you, the higher it is, the more memory you need, the lower the FPS amount.
Antsotropic Filtering - Personally I turn it off, it makes the edges of the textures more smooth but consumes your memory.
Shadows - I have turned them off, as the games has already finished textures including own shadows. Simply it won't generate any shadows of objects like players or obstacles.
Shadow Map Resolution - Put it on normal
Cache Sun/Spot Shadow Maps - Turn it off!
Post process option - I have turned them off, you can try by your own to make the game look better..
AA-Options - the AA is heavy on this game, don't even try to put it on 16x.
Shader-Preload - turn it on to have less sluterring in-game, but you will take much longer loading the game.
Miscellaneus-Options - Turn the bullet impatcs on if you want, the don't have any influence on your performance. Set the amount of dynamic lights on 2 to increase some rendering sped.
Advanced tweaks
In the multiplayer config (config_mp.cfg) you may edit some command lines to increase your game experience.
Raw mouse input -
seta cl_mouseAccel “0”
seta in_mouse “1”
Make sure mouseAccel is set to 0 (default value). Change the in_mouse value from 1 to 2, so it reads: seta in_mouse “2”
Now you will be able to get rid of your mouse lags.
Increasing the VRAM-Usage -
Set the seta r_videoMemoryScale to "1", you will take 100% of your VideoRAM when ingame.
Enabling SLI (Only NVidia-SLI-Cards) -
Patch your drivers to the Nvidia GeForce Game Ready 344.60 WHQL driver, you don't need to do this manually anymore.
Well, I hope I was able to help you in getting some more FPS, feel free to ask some questions in this thread or post your own tweaks!
