P3-700 slot 1, 512mb ram, geforce 4 agp: 140fps.
P3-1ghz socket 370, 512mb ram, intel onboard: 75.
Vsync off, 320x200, zdoom software mode. Surely the intel onboard video isn't crippling it to this degree. Similar result for an e1m1 timedemo also. And finally, the 700 is running windows me, the 1ghz running xp. Might put me on the 1ghz but it would be a shame because the xp install has all the drivers etc.
