hello guys .. I have a problem and I hope that you will help me ... I have a problem with unstable fps .. My hardware configuration is a quad-core CPU at 3.6GHz ATI Radeon HD 5750 1GB DDR5 and 4GB DDR3 ram and my fps is 60 but sometimes it drops to 30fps and its very lagy .. pls help ..

Well, ~60 FPS is the 'smooth' limit, so either you have it locked onto 60 or your PC sucks.

Lower your settings and see if it happens then

Uncheck "Specular Maps", "Shadows" and "Depth of Field" in your MW3 Video settings, and you will see a big FPS increase..

lol im trolling on 30-50 with the half of the power of his pc

quad .. core you should STUCK on 99 fps etc < the limit

question laptop ?

Specular Maps and Depth of Field are set to OFF... thanks for your time...

So I guess you are getting reasonable FPS?

Any other 3D applications running in the background?

hmmm I think its cause you use 12.11 beta drivers for your ati graphics card... if you are using beta drivers try to revert to 12.10 catalyst and see what happens

Your graphic card isn't any "beast".

Either the GPU is overheating, or you're hitting the physical limit for windows file cache (those 4GB of RAM)

It's usual for games to start lagging like hell when the RAM gets depleted (most commonly on x64 OS computers with low RAM, like those 4GB)

Keep in mind that a 32-bit OS can only handle up to 4GB of RAM, but 64-bit W7 was made for up to 192GB of RAM

I got 32-bit os and 8 GB Ram, I have made a duplicate kernel and then unlocked the ram, so now my 32bit os use the full 8gb ram

I have made a duplicate kernel and then unlocked the ram

Well, that seems a nice adventure (really, I like those kinds of "tests")

But is that stable? Wouldn't it be more stable to just put a 64-bits operating system?

I'm a bit curious on what are the advantages of that configuration that you have now?

now everyting is fine and i get stable 60 fps.. thanks
