Adjusting the Maximum Prerendered Frames and it's effects on gaming performance.

post #1 of 4
Thread Starter 
I ran these benchmarks on another site because the topic had come up. I know there is not much of a performance difference, but if you are benchmarking for the best possible score it might be a good idea to adjust the Maximum Prerendered Frames setting to Eight [8] in your Nvidia Control Panel. Nvidia states that this setting can help provide smoother gameplay at lower framerate. Another thing it seems to do though is gives the chance for higher highs in FPS measurement. I think this is because setting the value to 8 permits, but doesn't force, more frames to be prerendered. Whe the CPU has it easy then more frames get prerendered for use by the GPU. These are the results for my Gateway 7805u, 2.26GHz and a 9800m GTS.

That's interesting to note. I have it set to eight on my little brother's rig that has a GeForce 6200. I don't really think it helps him much when he's playing MapleStory though.

Yes, but as you go higher with the pre render limit, input lag increases. Well, at least in my experience.

EDIT: Didn't read OP, only looked at pictures. Agreed that it's only useful for benchies.

It does have a few offbeat uses as well. Morrowind lags worse in Vista when it is loading a new area. This helps shorten that pause.

I've set MPF to 8 in my Global Setting. I don't see anything but upside in doing so as input lag issue isn't an issue for me the way I play I guess. Also, this was done with a rather weak CPU/GPU combo, so I'd expect a little better results on OC'd Quads and GT200 cards and SLI.
