Hi guys. I've been messing around with socket 3 stuff again, and I'm puzzled by the poor performance of the Pentium Overdrive in GLQuake. Is this normal?

In dos quake the POD83 scores 19.2 FPS - highest score out of the 3, followed by the Cy5x86 120 (enhancements on) witch scored 16.1 fps and the Am5x86-p75 running at 180MHz (3x60 / 4v) witch scores 15.8.

In GLQuake the cyrix scores 20.8 FPS (with sound) and 23.7 fps w/o sound and -particles 0. The 180MHz AMD scores ~21FPS (when it doesn't hang while running the benchmark) and the POD83 only manages a meager 14.2 fps - witch is on par with the 133Mhz AMD 586... what gives?

The mainboard is a Lucky Tech LS486E C2, running 256kb L2 cache and 32MB of EDO DRAM (scores are lower when using FPM). Bios settings are tweaked to suit each CPU (ex. the cyrix fails to boot if I set L2 tag bytes to 8 bits, while the POD and AMD run fine with 7bits).

I tought the board does not like the POD very much, but I got comparable results on my BIOSTAR MB8433UUD-A.

Any ideas?

A POD 83 MHz runs more or less on par with a Pentium 75 MHz.
If you refer to the attached link, then your POD 83 MHz's performance is more or less in line with the benchmark results.

However, you mentioned GLQuake.
What 3D graphics card (if any) are you running it with?

Voodoo 2. I did find the issue tough - it was the miniGL driver. For some reason the 1.47 version doesn't like the POD (or my setup). I got much better results using miniGL 1.49.

As for the link above, it's actually the reason I opened this topic.

tl:dr - the problem was the miniGL driver
