I happen to have a GeForce Go 5200 (yeah, I know...old) and running Kamui gives me some wierd display glitches (I could hear the music but no image). Plus the fact that every time Windows boots up, the automatic fullscreen native stretching no longer works.
I tried reading some notes on the updates (roughly via google translate) and it mentions something about Kamui having issues with GeForce cards. Anyone else encountered this problem?
