I bought a new low end PC to help with testing.
Sempron 3200+ Processor (timed at about 1.56 Ghz), 256 MB RAM, ATI Radeon Xpress 200 Integrated Graphics Chip
It runs about 1/2 the framerate of:
Athlon 64 2800+ Processor (timed at about 1.80 Ghz, 512 MB RAM, ATI Radeon 9600XT AGP Card
Is this a graphics card limitation or a CPU limitation. The new PC runs Doom 3 fairly well with only a slight difference between shadows on and off (CPU calculated). This new PC also has a PCI Express slot so I'm tempted to try it out but I don't want to invest if the processor is the bottleneck.
