Did you use FASTVID while testing?

No. Should I ?

Quake in 640x480 seems to be limited to 60.6 FPS.

There is no hardcoded limit.

I had around 90 FPS on an AthlonXP system in that resolution, when using FASTVID.

I will test FASTVID !

So. No difference with fastvid : 60,6 FPS.

Turn off vertical sync or setup your monitor for refresh rate higher than 60Hz 😀

If you haven't done so already, patch Quake to v1.08. Also, disable VSync by editing Quake's config.cfg and setting these entries to zero:

1vid_wait "0"
2_vid_wait_override "0"

That together with FASTVID, should allow you to get the maximum FPS that your CPU can deliver.

But why did I get more FPS in other definition ? With the same monitor ?

FASTVID only works in pure DOS. If you're benchmarking Quake from within Windows, it's likely the GPU drivers already enable the relevant write-combining features.
