-
- 5ms is the time for copying a 2x2 frame.
- 10ms is the time for one blitter pass.
-
- The values seem to make sense, but isn't it rather 7ms for cpu doing
- passes not completely free, and 10ms for one blitter pass ? ;)
-
- BTW how much is the 2pass routine on 020 ?
-
- My one pass routine needs 10ms for a 2x2 screen, so 2times more than
- copying, I hope doing 2 passes is ~15ms and not ~20ms...
