Sorry to keep bringing this up but I have a little free time and I'm curious about the outcome.

Both Solaris and Desert Falcon set the timer (TIM64T) during vertical sync. I don't know if that matters but it's a noticable difference :)

I also looked at Bob Smith's Dragonfire source (this needs to get on The Dig!) and he is doing other processing during the vertical sync too. Dragonfine does VSYNC on scan line 4 and cycle count 0. He sets the vertical blank timer until after the vertical sync.

Take care,
Dennis
