If you are going for speed in DOS Games, it is more important, which CPU you are using.
I would also second the Virge/GX over the Trio64(Diamond) > Trio64(Expert Color) > Vision864
IF the Vision864 has 2 Mb RAM
if it has 4 Mb Ram, and you also want to use it in windows I would prefer the vision 864 over the S3 Trio64 but not necessarily over the Virge.
Advantages of the ViRGE:
- not less than 2 Mb Ram
- 170Mhz Ramdac(Trio64: 135Mhz, Vision864 depends on the card)
- Best compatibility(Worst: ATI - nearly the same: every other S3 card)
- S3D
- VBE 2.0
Possible Disadvantage:
- Maybe a little bit slower in Dos compared to Stealth64, depending on the CPU(if the card is the bottleneck)
Try the ViRGE first and compare it to one of the other S3 cards. If the result the card is producing is okay, stick with it.
Would prefer the following order, if you try to measure it: Compability, Output Quality, Extra Features, Speed
PS: GX should also come with VBE2.0 if the DX is...
