Tested games: 331 winglide and 30 dosglide.
V2 SLI (w2k 1.02.00 drivers) + P4 3.2E + 2 GiB RAM + WinXPSP3:
You must tweak V2 drivers (set fxgpio and fxptl as system services).
All except 2 winglide2x and winglide3x games run ok (some with WinXP patches).
Hind has a black screen in the flight mode (there are sounds etc). The game isn't playable.
Midnight Racing runs but with graphical bugs (a garbled text).
FIFA 99 and World Cup 98 can freeze but voodooa.dll update fix this bug.
All "minigl" games are ok. HL games have an annoying bug with minigl 1.47 and later - no cursor in the ingame menu.
Winglide1x games - not work.
V2 SLI + P4 3.2E + 2 GiB RAM + MS-DOS 7.1.
You must use GLIDE2X.OVL from 3.03.00b or 3.02.02 w9x drivers (the fast CPU bug).
Statically linked games - not work (can't detect a Voodoo card).
Dreams to Reality, Prost Grand Prix, Screamer 2 (1031 KiB patch) freeze before the 3d mode.
Archimedean Dynasty, Battlecruiser 3000 A.D. (1.x and 2.x), Lands of Lore: Guardians of Destiny - more testing is needed.
The others dosglide2x games are ok (again, you must use 3.02.02 or 3.03.00b GLIDE2X.OVL). Some games need V2 patches.
About the speed related bug - a game a) freezes or b) can't detect a Voodoo card on fast CPUs. A) is related to the 3dfx logo, "set FX_GLIDE_NO_SPLASH=1" fixes this (no logo = no bug).
