GPU or CPU bound? uMark scores never change

Hey guys, I was running uMark today and noticed my scores were the same no matter what my monitor rez is. Is this an example of my sempron 2200 holding back my 9800pro?

Thanks ChooChoo

Check to make sure your benchmark is not changeing the rez. Most benches run at on res and will change from your windows res to the one the program is set to.

sorry i dont understand what you are talking about. my scores are within 2 fps of each other. is does not matter if my monitor is at 640 or 1600.

thanks ChooChoo

but is it set to 640 in the benchmark or in windows? the reason i ask is the benchmark programs generaly change the resolution when the start.

ok i see what you are saying. i windows is set at 1024x768. i ran a set of uMark to run 640 then 800 then 1024 then 1280 then 1600 and yes the rez is changing when the benchmark runs. All the scores are within 2 fps of each other, on the same map. I am not complaning as my scores are 60fps (way better than my Mac). But you would think that i would get better scores at 640x480 than 1600x1200.

thanks for the help, choochoo

It sounds like you may have Vsync on.

Yeah could be that too.

/me kicks himself for forgetting that

I just looked, vSync is set to false. This is so odd, I got 1 fps better on 1600x1200 than on 640x480

Keep the ideas rollin in guys!!

Thanks ChooChoo

Make sure that vsync is disabled in the ATI control panel as well. It should be under the 3d tab. You'll have to change it for both OpenGL and DirectX. Anything set in the control panel (driver level) will override any game/benchmark settings.
It is likely that your 1.5 GHz Sempron is the bottleneck.
Unreal is very CPU intensive game.
