Cannot turn off G-sync on ROG Swift

Question - Do you have Shadowplay ON, with Desktop Recording on? For some reason in the latest drivers, this has been causing very slow performance on the second monitor. If so, turn off Desktop Recording and kill DWM in Task Manager, or restart. This will solve your second screen lagginess issues, or at least did for me.

You must turn off G-SYNC in *two* locations in the Nvidia Control Panel. You must uncheck it on the GSync tab, and you have to turn it off in Manage 3D Settings. Scroll all the way down to Vertical Sync and you'll see an option that says "G-SYNC" with the Nvidia logo next to it. Select it, and drop it down to "Let the Application Decide" and click Apply. G-SYNC will now be off. You will have to check both boxes in later if you want to re-enable G-SYNC.

Curious though, why are you disabling it? I mean yes, G-Sync will framecap you at 144 FPS, but your eye won't tell the difference between 144 fps and 150+ fps. No, this isn't an argument on the condition of the human eye, etc. I mean that literally, your monitor can only refresh a frame once every 1/144 seconds (6.94 milliseconds). If you are pushing above 144 FPS, and you *are not using G-Sync*, you are just dropping those extra frames. This is part of what causes tearing to begin with.

If Shadowplay isn't running, try just killing DWM in Task Manager. You should notice some extra smoothness. Also, Shadowplay records *way* better than FRAPs if you have a 7-series card or better, just saying.

Make sure you disable G-Sync in the order I described. First from the uncheck box, then from the dropdown menu in Manage 3D Settings. You must do it in both. You can tell if it's off if the bottom right of your monitor where the power button is if the tiny LED is white instead of red. The giant ring under the monitor *is not* the G-Sync indicator, just to be clear. If you're having issues with G-Sync re-enabling itself *inside* Nvidia Control Panel, try doing a Clean Install on your Graphics Drivers. To do this, download the latest drivers from Nvidia.com, and then choose Custom Install. When it shows you what drivers will be installed, click the "Perform a Clean Install" checkbox. This may fix your issue, as I recently had a driver update that completely removed G-Sync functionality from my Control Panel, so maybe you're having the opposite problem.

And Yes, at 10 fps anything is hard to use, let alone the mouse. But your panel *can only refresh* at 144 Hz (1 frame every 1/144 seconds). If you go up to 150+ FPS, you won't perceive any faster mouse movement than 144 Fps, because your monitor is capped out.

This is also why 60 FPS on 144 Hz "looks" smoother than 60 FPS on 60 Hz. The monitor refreshes the frames faster (every 6.9 milliseconds vs every 16.67 milliseconds on a 60Hz screen) so you perceive smoother mouse movement. But once you're at the frame cap, going *higher* will not gain you anything. I'm not opposed to turning your resolution down to get as high as you can. I'm just saying, if you're already banging above 144, there's no point in *not* using G-Sync to reduce stuttering from framerate drops when, say, 3 grenades go off on screen during a match. My point is, there's literally no reason to *not* be using G-Sync if you have a card and monitor that support it, and are hitting 144 Frames in your games.

I'm glad the DWM kill solved your issue. Hopefully it doesn't recur. If it does, I would still recommend the clean install of your graphics drivers. It solved a few of those wonky issues for me (including DWM randomly taking up a lot of CPU %) and hopefully it'll solve your GSync concerns.

And sorry, I didn't mean to presume you didn't know, just thought I'd cover all the bases, especially since I ran into a few people on the ASUS boards who thought the ring was supposed to change color, not the tiniest LED ever lol
