Can someone please help me out? I have a really annoying issue with my setup, I have an nVidia GTX 1080, 64GB ram, i7 6820HK with Widows 10 Creator's update installed. It is a high end gaming laptop (Asus G701VI). with a built in 120hz G-Sync monitor. On certain games like Forza Horizon 3 and Rise of the Tomb Raider having G-Sync enabled causes bad frame skipping/lag/stutter (not sure what to call it), but only when set to 120hz if I change to 60hz it's fine but obviously it runs at a lower frame rate then. Interestingly the FPS counter still reports a high frame rate (between 100 and 120) but that is not what I am experiencing on screen. If I turn G-Sync off and set the game to run at 120hz I get perfect performance, almost constant 120 FPS with no stutter, albeit with occasional frame drop as is it to expected. I am totally baffled by this. I am running the latest drivers (at the time of writing this v382.05). Can anyone offer any help?
