Re: S3 Virge drivers + Win 3.11 + High Res modes heavy glitc

That's to be expected. The SVGA drivers aren't supposed to be compatible with everything. On a real PC i've only had the SVGA driver work on Tseng and Realtek video cards, in my experience ~93-94. Also it's not the best driver either - it's slow and has some brighter-than-usual colors, such as dark ...

Re: What is the best configuration for ReactOS\WindowsXP

I wouldn't bet on ReactOS being stable - I never had it working on a real computer (kept hardlocking on a P2 machine) and the community often suggests only using virtualmachines with it as it seems developed exclusively for them.

If you plan on playing 3dfx Voodoo games in their emulated natural habitat, it's quite faster for that now (compared to 10.1)....though an i5 laptop won't cut it with 2 hyperthreaded cores probably.

Re: [PATCH] Fake Cyrix 6x86

FWIW my models list was based on what I saw here. The earlier 6x86 models definitely did have an identification issue so it's not expected to have XP (or even Windows Me) working on them. You can't install Creative's WaveGuide on them either.

Is dynamic recompiler enabled? You should be able to hit 100% on the lower Pentiums with infinite cache with that cpu, and 486dx4 100 shouldn't be an issue

Quake's nothing. You can burn through in p166 a lot cache on a Phenom II on that with a pgo build, runs 100% and performs roughly similar to Pentium laptops of the era

Re: Writing down about performance in PCem

I'd say Phenom II 3GHz is a good min for 3dfx emulations assuming P133 A Lot cache. It's enough for skirting along Turok on 512x384 with the filter disabled. Having two threads for it is also a big help, and there's still more room for speedups (like using SSE2 to handle the texture mapping) random ...
