Does this mean that scrolling games will be slightly 'chuggy' when using the new Indivision?
Unfortunately yes. Unless you have a perfect 50 or multiply thereof, there will be jitter
How bad is this expected to be? "noticable, if you know about it." "bugging you, regardless of pre-knowledge" "useless for scrolling games"

Indivision AGA MK2 will have enough memory performance to do that - and it has the exact same effect that you desire: Having the VBlanks synced.

You may not want to use that output on NTSC, as it would produce 90Hz output. The current Indivision turns an NTSC screen into 75Hz output if you're using the 1.25 mode, and we even get support requests because some monitors can't handle 75Hz. This is why the factory setting is now "60Hz for NTSC and 62.5Hz for PAL".
Will this be a setting you can play around with somewhere? Seeing as newer sets will support more features, possibly allowing better end results... (this looks promising, but i still anted to ask)

Indivision AGA MK2 will have more choices of pixelclocks, which brings it much closer to standard PC gfx modes. This makes it compatible with more monitors.
Above all else, i haven't seen it mentioned so i assume it's been "by default" but... This will work from power on, nothing loaded, no drivers, no software running, nothing. Possibly the thing has to be configured, but after that it's all on the unit it self, so the miggy doesn't have to boot an OS to be able to display games on the Telly... Right?
