Been having samekinda problems as is explained in this thread, and tried some of the things here. Normally i have set 120 max fps w/o vsync, when i turned max fps to 59, my game started to look like that Bronk's video all the time, just unplayable. Then i tried 90, it seemed allmost like with 120, but when i turned vsync on it seemed to fix that odd movement style characters had most of the time, and it seems like the animations are alot better now. So with my machine vsync seems to work out most of my problems.
Well, the movement and animations are better now, but first time ever i got this odd "stuttering" that normally comes with horse, when i was foot, tho it was after i was dehorsed, and it last until round end. But still it feels alot better overall with vsync then it was w/o it, but ive only played couple hours with it.
