Hi Irinikus,

and here are some additional results from O350 with V12 (Onyx 350 Infinite Performance):

Quake 2 (Q2) & Quake 3 (Q3)

For Q2:
setenv DECOUPLE_SWAPBUF y
timedemo 1
map demo1.dm2

For Q3:
\timedemo 1
\demo four

O350 with 4 x 800 MHz / 8 GB RAM / V12 @ 1280x1024

Q2: 689 frames, 19.0 seconds: 36.3 fps

O350 with 4 x 800 MHz + 4 x 700 HHz / 16 GB RAM / V12 @ 1280x1024

Q2: 689 frames, 13.9 seconds: 49.7 fps
Q3: 1260 frames 48.0 seconds 26.2 fps 18.0/38.1/76.0/8.7 ms

O350 with 4 x 800 MHz + 4 x 700 HHz + 4 x 1 GHz / 24 GB RAM / V12 @ 1280x1024

Q2: 689 frames, 15.8 seconds: 43.6 fps
Q3:1260 frames 49.6 seconds 25.5 fps 19.0/39.4/82.0/9.0 ms

So this shows that throwing extra CPU at the problem does not improve the performance and in fact it reduced the fps result. Consistent with view that performance is driven by graphics fill rate.

The results shows the grunt that your IR graphics has for handling the OpenGL rendering.

I might run Q3 on my old MacPro with Nvidia card and see how it performs out of curiosity.

Cheers from Oz,


John.
