With a 030 you'll get around 9FPS running it almost full screen. Use 320x200 with AGA.

Mediator+Voodoo3 will be slightly faster than AGA, perhaps you get 1 frame per second more if you write directly to the gfx mem.

With a ZorroII card it will be slower than AGA

Yes, *any* zorroII gfx card will be slower than AGA when playing software rendered lo-res games like ADoom, Quake... 040/060 cpus perform chunky2planar at copy speed. That means it takes the same time to copy any random data from fastmem to chipmem than it takes to copy data from a chunky buffer in fastmem, transform it into bitplanes and copy the result on the fly into chip ram.

AGA has a bandwitch writing of around 7MB/s (IIRC) in optimal conditions while you can only expect half of that with ZorroII in optimal situations (I think Jens Schoenfeld or Michael Boehmer pushed that a little with some of his ZorroII cards, reaching around 4.5MB/s (IIRC) but it's not common).

In practice ADoom is much faster using amiga custom chips than using ZorroII.

You can also try out things like WarpOS VoxelSpace demo... ZorroII is damn slow for these things.

ZorroII cards are quite good for "high-res" displays like 1024x768, as soon as you use more than 16colours most of ZorroII gfx cards will run rings around AGA.

On a 320x240 256colour screen AGA wins :-)
