Another fun project in progress.
Newest version Windows 11 (pure uefi mode but secure boot disabled) and 3Dfx voodoo1 from 1997
Asrock H77, Xeon 1220v2, 16gb ram, 256gb ssd, HD6570 for 2d whitout drivers so no hw acceleration, chieftek 450w psu.
Windows is modded to accept the unsigned driver, limited to 640x480 16bit for compatiblity. I use the modded windows server 2003 x64 drivers (XP x64) for the voodoo.
CPU is too fast, at stock speed the games not recognizing the card, at the lowest 1600mhz games are starting but freezing.
There is known bug on these cards, over 800-1000mhz cpu cards not working. (not even in dos!)
At full cpu speed unreal1 glide, not starting.
And at 1400mhz:
(i disconnected the 2D card to prove the voodoo is started so the windows is passing the glide api to the card)
So it is a very little success.
I have a pcie to pcie adapter for the newer platforms. So it is possible to use hardware glide acceleration even on win11 but i need to fix the cpu bug first.
