I'm getting great functionality from 3DFX Glide - everything in-game is running smoothly and the effects are gorgeous. My only small issue is that there is always ~10 seconds of loading every time I launch the game, go to the main menu, start playing, exit to the lobby, start playing again. The loading screen is fully black and there is an alphanumeric scroll on the top left (1,2,3,4,5...!,@,#,$....etc). I did some searching around, and feel like i've tried every suggestion possible: running it windowed, disabling Windows Desktop Effects, Run Video Test, Force Kill WDM after launching, messing with admin privileges, trying different compatibility modes - nothing will get rid of the black loading screen (on Win10 64bit)
Thankfully, its only ~10-15 seconds each time which isn't bad, just seeing if maybe there's something else I haven't tried or thought of yet. Otherwise, loving it!
