in my experience in 3d shooter' games ....AGA is always faster than any gfx card...even compared with the fastest zorro 3 cards like the picasso 4 or the cybervision 64 /3d
AGA in PAL mode or NTSC beats any gfx card
the few exceptions are of course if the game uses warp3d libraries where the 3d engine of the gfx card do all the work....for example GL quake
That's what I've seen. The best performance I got was with PPC quake running with AGA screen. This was way before any AOS4 stuff. There was some illegal port or something I got hold of and that thing worked great, back in the day.
Kinda sad, that we can't get it to work better on an 8 Meg graphics card like B-Vision...
