- What about good old 50hz? AGA bandwidth matters here..

- Flight Unlimited runs in a 320*400 (I think) screen with full detail in
- 3 or so frames on a 486 DX2/66 with a *very* below average gfx-card..

-
- But the problem is that nothing supports them.. We need a standard,
- not just OS solutions.
-

-
- Who said you had to write bytewise? I use a mem-buffer, and copy
- longwords to the gfx-card. MUCH faster.
-

-

- Perhaps not, but the slow chipmem does! The only reason C2P is free is
- because the chipmem is so slow!
