Ah, thanks a lot, that's helpful -- so I expect S-Sync "1" + Fast Sync at say 30 fps (S-Sync half refresh rate for example) will still microstutter/have that jitter occasionally then. Argh -- thanks RealNC, that's great to know! Why not just do a manual FPS cap of 30 + Fast Sync then? Or is S-Sync "1" preferred to that? Thanks, sorry to spam you.
