- I'm not convinced ;)
-
- if it really does 70Hz then it has a timer-emulate-vblank-interrupt hack
- (don't think so) or does busywait for the vbl bit, i.e cpu locked up
- with testing a bit, even worse than scroll by moving data.
-
- Anyway linux is not known to have any reliable jerkfree task running.
-
- Megablitter, Megacpu, in your case even Magamouse. but Jerk ;)
-
- naah those old inferior '85 chipsets. I got 120MHz. jerk jerk. ;)
-
- The hp workstation (whoa!) I use right now not only jerks
- but also rastersplits. I does virtualscreen with blitter,
- and I guess most (all ?) X drivers do so ;)
