>20% 16.67% (ntsc games are 20% faster than pal games) >You can't reliably get vsync (and you generally can't get it at all, in windowed mode)[...] Vsync works in windowed mode with opengl on nvidia and ati cards. But I've often seen a fixed tear line in the upper third of the screen with ati setups. Dunno really whats the reason for that. Guess you mixed that a bit up with java2d. Well, but its of course true that you cannot tell if enabling (trying to enable) vsync worked. With nvidia cards the current state can be querried, but thats the only exception. Other vendors dont think its necessary to follow the spec in that regard. Ah well... backing it up with a framecap doesnt hurt anyways and its certainly more robust. edit: Oh and even if you dont port it over to consoles, you still might get some PAL drag. I'm using an ati card right now and if tv-out and vsync are enabled I cannot exceed 50fps (hz of the primary display doesnt make a difference). Pretty annoying, isnt it?
