DoomAttack was fastest engine on 68020 and 030.
Much better on 68030.
i played DoomAttack when was released and on my 68030@50 Mhz i played with 13/14 fps with Doom for the first 3 episodes.
Ultimate episode was very slow on 030, i finished the game with 68040.
2 fps is too slow..
i think you should play at 10-12 fps.
When i had only 4 MB of RAm, some games and demos are very slow, but with 8 MB..a great improve in speed.
