Today I checked to see if the "timedemo 1" command works in ioQuake3 on my O2 R12K@400MHZ. And it does! ...

Just wondering, does it make any difference to your Onyx2 results if the running environment has the following added to .cshrc? It might go up a bit with O2, but it's the big iron that interests me (O2 is too fill limited for Quake3 anyway).

Code:

setenv DECOUPLE_SWAPBUF y

With regard to performance, all the Quake ports for SGIs were very rough and ready, none of them are properly optimised for SGIs, so indeed there's often heavy CPU dependency. I'm not sure if this means whether at higher resolutions the CPU dependence is made better or worse (with modern PC games it varies). I only bothered testing Quake and Quake 2, though I need to redo some of the tests with single buffered active:
