IS MY GTX NOT PERFORMING?

Hello, recently I have been benchmarking a few of my games. I compared my fps with the fps on Guru3d. I noticed that my frames and much lower and was wondering if there was something wrong with my card?

Battlefield 2 guru3d sates that on 1600x1200 you should get an average fps of 186fps. Me on the other had gets about 150fps.

F.E.A.R. Now I only have the MP demo for this game so it might be patch related but on guru3d it states I should be getting a fps of 112fps @ 1280x960, http://www.guru3d.com/article/content/401/11.
I however only get even a max fps of 60 or so.

I just wanted to ask as I am worried with games such as crysis coming out in the next few months my card wont perform like its supposed to and therefore should I send it back? my current drivers are the ones on the nvidia site (162.18). I am on Windows XP pro 32bit and my specs are as below. Thanks:) Also does my 3Dmark 06 score look normal (specs below) It is only on 1280x960 because i took that with my old screen, now have new one @1650x1050.

Hmm, there is some patches for Windows, not sure if Vista only for Single cards and a SLI/Crossfire Patch, then there is newer beta drivers avail that give big gains esp needed for BioShock.

Thats all i can think of now.
 
for F.E.A.R have you got v-sync enabled? if so then it won't go higher than 60fps or whatever your monitor refresh rate is
 
oh dear lol. You were right about the vsync. It was turned on, can't remember switching it on but anyhow... my fps are now as follows for F.E.A.R:

Min:68fps
Avg:135fps
Max:351fps

A hell of a lot better :P

Also while changing the vsync options I desicoverd something else. The whineing/screeching that the 8800GTX/GTS cards sometimes makes, mine unfortunaty was one of them. And when I turned Vsync off it made a right racket...but when I turned it on it was dead quiet lol? Wired. So the noise is either related to vsync or related to FPS (too fast). In which case is a bit silly because that basically means the card it making noise because its perormance is too good :P lol Anyway thankyou for helping me. Can't belive I didn't try that earlier. Never mind.:)

Yup, with vsync on your limiting your fps to you monitors refresh rate. It wastes lots of time sitting around waiting for your monitor to be 'ready' to draw the next frame.

With vsync off it lets loose full whack and therefore needs more power from your PSU. Thats what causes the whining.
 
You cannot really compare your system to reviews as the review machines are usually very limited Windows installs with very little background stuff and possible no audio to boost framerates.

Isn't tearing on a CRT absent due to the whole image being displayed at each refresh?

I think tearing happens when the framerate goes from being above the refreshrate to below the refreshrate, in other words on a TFT when the framertae drops from 65fps to 50fps, on a CRT the refreshrate is much higher so the chance of it happening is much lower as the framerate is mostly below the refreshrate all the time.

Nope, there were no TFT LCD monitors way back and we all used CRT and V-Sync was around.

I read a very detailed report on V-Sync, most was way too deep and over my head, but its not as simple as your HZ = your FPS if its on.

I also dont think it has to do with a CRT having the HZ higher than the FPS, as I get 70-200FPs in games like BioShock and at 1920x1440 my HZ is limited to 75HZ in Vista64 as I cant install Monitor Drivers (it may be 75HZ anyhow for that RES).

tearing happen because the graphics card is sending frames when the monitor is on a vertical blank (in interrupt basically. in this instance, the time between finishing displaying a frame and waiting to display the next), or when its half way through drawing a frame. things become out of sync, any the monitor is only displaying partial frames. by the time the monitor is half way through a frame, the graphics card has already sent the next. this happens at any refresh, on any screen.


thats why we have v-sync - to sync the timing of the card and monitor so each frame is sent and ready for the monitor to dsplay.
