I checked my Quake folder and first tried BlitzQuake again - just Warp exception. It may be the same thing that happens with ADescentPPCW3D version, it doesn't work either. It stopped to work after the latest WarpUp update but works with the earlier version - perhaps the same is true with BlitzQuake. The 68k Blitz worked OK - 8+ fps with 800x600... I found at least 4 different GLQuake beta versions, but the version numbers are lost as are the dates, too. Beta 2, Beta 10 and two other. 2 versions have the bug that the control panel down on the screen is corrupted (I think I reported it to Massimiliano back then). 800x600 gave some 19+ fps on 800x600 on timedemo1 (Mediator is a couple of fps faster).
