At 320x200, you're limited by the CPU, graphics card vs AGA and Zorro bus have very little influence. In fact, my A2000 and A4000, both with 060/50 and Picasso IV performed _identical_ in the timedemo benchmarks. At 66MHz the 4000 was 1 FPS quicker IIRC.

You might notice a few FPS difference at higher resolutions, but they are generally unplayable anyway. 640x480 is somewhat doable if the screensize is set very small.

Damion: Is it possible that you have forced your Picasso 4 to Zorro II with jumper? And actually used it with your A4000 as a Zorro II card?

Nope. Results were where they should have been, around 9 FPS at 50MHz and 12 at 66MHz, using Clickbom Quake. It does help that the Picasso IV uses the Z2 bus very efficiently - 3.5 MB/s for writes (bustest), around the maximum possible. Other cards (the CV64/3D for example) are quite a bit slower. I'm sure there's a greater difference at higher resolutions, but I never tried.
