PPSSPP is pretty light anyway, so it doesn't really matter for me, but worth mention it's quite likely the first windows app using this backend which I don't have problems with. Not sure, if it's because drivers improved alot recently or simply ppsspp is much better coded than commercial products/games using OGL on windows which terrorized me in the past.;]

This might be because I am mostly a linux user and I might be bashing AMD because of it too much but nvidia GeForce 8 Series from 2006 are still getting updates and on linux they are good drivers and AMD driver support is just horrendous on linux.
Any way thank you for the information .
