Screen resize slowdown 80Mhz 060

[bbond007]

I got my 80Mhz 060 back from Poland. It is quick as can be, but...

When ever I am in double scan mode or have another program like Ocamed ss open, the screen dragging process becomes slow and cumbersom.

Anyone know what causes this?

If you had a Indivision MK2 or some other sort of flickerfixer. You could run in interlace mode which will be more than twice as fast. It is with Shapeshifter anyway... Interlace mode runs 1X mac quadra 950 speed where as multiscan mode runs about half that and seems to really drag...

Double PAL/NTSC will use double chip bandwidth, so deeper screens (>16 colors) may become really slow, regardless of CPU speed.

Displaying a Double PAL (or Superhires) screen with 256 colors will use up ALL available bandwidth in the scanline. Any screen manipulation by CPU or blitter can only happen during the rather brief horizontal and vertical blanking periods.

oops, already said... totally agree...
