Call of Duty 2 - 99% CPU Usage!

That cpu is definately a bottleneck ;)
I had that cpu and used to get about 300fps in COD2 now swapped over to Intel E6600 and get 600-1000fps with the same gfx card.

Also used to be 99% usage now only 50%

AMD's are officially poo now =D

E6600 is dual core, so naturally in any application which isnt really designed for multithreading the CPU load will hover around 50%.

Easy way to determine if its a CPU bottleneck, set the game to 640x480 and benchmark. This is so easy for the GPU, even a slow one wont struggle, so it will normally bottleneck on the CPU. Then switch to your normal play resolution. If the performance is the same (or within 5% or so), then the bottleneck is the CPU. If the higher resolution is much slower, then the GPU is the bottleneck.

In general the CPU have very little extra work to do in high resolution games, than it does in low res games, while the GPU is more stressed the higher res you go. It's not a perfect test, but good enough to show which parts are bottlenecks.

Either way 100% CPU load on singlecore, or 50% CPU load on dual core (or hyperthreaded cpus) are 'normal expected' results for most games.
 
what is this about all games using 100% of the cpu? the only time my 146 gets to 100% is when it cant handle whats being displayed on screen, otherwise for most new games its between 70 and 100, cs 1.6 uses barely 30% :confused:
 
my cpu usage is quite high too on COD2. but as a test i managed to get the cpu usage as low as 30% but that was running the game at 1600x1200 with 4xAA.

usually i run the game at 1152x864 with 2xAA for proper framerates.

That can't be good, surely? This points straight to a CPU bottleneck I think . :(

A64 3200+ @ Stock
x800XlGTO2 OC'd a bit
2Gb RAM (4 x 512mb GEIL value)

I was hoping to get an x1800xt from OCuK but if my CPU isn't even up to the job of an x800 there's no use. Is this the case?

Thanks for any help.

Games usually run at 100%
 
Well its still dependant on the way the game's written. If the game allows windows to manage cpu/idle then it will have a lower CPU utilisation. If the game does all the work 'in house' then it will be 90-100%.

Some games even work differently depending on if they are running full screen, or windowed.

Well, I would have though you'd want a game at 100% anyway, and maybe even on high priority as well... after all, you don't want to lag.
 
this is what i get running a SD 3700+ with wmp playing in the background and also IE7 running.
