Wow, I've never heard of someone running a game on PC Task before. I
once tried a basic text adventure which was interesting to see it
going on A1200.
As for games that make use of the '030, I think anything that slows
down when there's too many onscreen sprites will be speeded up. The
68030 is as compatible as the '020 unlike the '040/'060 so even
hardware hitting demos will move smoother.
The 68882 50MHz FPU is good too and will speed up Breathless and
possibly the 2x Alien Breed 3D games. Gloom is also much nicer.
I thought XTreme Racing was quite fun but to get Mario Kart style joy
you really need an '060. With an '030 it just doesn't go that fast in
full screen modes as there is possibly a lot of work done that would
eitherwise have been handled by ASIC chips like the SNES's Mode-7.
Certain A500 games like Elite and Syndicate might be a little too fast
or crash though, so disable the '030 if you get trouble by holding "2"
on the main keyboard at startup. Re-enable the '030 by holding
Ctrl-A-A for 15x seconds.
Just for fun, why not try the PD game WBsteroids. It's like Asteroids
that opens in a Workbench window and will definately love your extra
processing power!
