- nooo. it's not easy to get it ideal.
-
- It is 4 pass blitter on a 020-14+fast doing doom.
- it is maybe 3 pass cpu on a 030-50.
- it is 1 pass cpu + 2 pass blitter on a 020-14 doing chunky gouraud.
-
- etc. ;)
-
- your 2+2 example would be a 020-28 doing doom.
- blitter would need 2.5 frames for 2 passes on 320x160 1x1, so
- even useful for 030-50.
-
- But on 020-14 even 1 cpu pass is too much when dooming.
-
- (exception could be vanilla A1200, maybe cpu overtaking 1 pass
- is better there. don't know)

- so what will rtg do on AGA ?
- drive the 040-c2p and be far too slow on 90% of all Amigas ?
- drive 2 + 2 c2p and brake 040 animations ?
