I thought an 040/25 MHz were faster than an 030/50 MHz. I played this on a 68030@50 MHz wirh 48 MB of Fast mem and I got 2 FPS in the smallest screen size. To play Quake you need a FPU or the game doesn't work.
Play Quake (Clickboom version with 060 patch) on a 68060@50 MHz with 128 MB of Fast RAM, I got 10 FPS in Full Screen, with the open source version 14 FPS. This on AGA resolution 320x256 (PAL).
