Ok, that 'tearing' is in fact much different to what I've been seeing, in y=
our
case it looks a lot more like *corruption* as entire chunks of buffer are b=
eing
rendered in random offset positions. I dont really know exactly what might
cause this, but I do know that running applications in fullscreen at a
different resolution to native can result in various buffer corruption...

Windowed, I rarely run things in fullscreen, of which it's usually borderle=
ss
windowed anyway. I don't remember if setting the vblank mode actually worked
though...
