I've just installed these this morning and normally I do not restart my PC immediately after as my PC is usually turned off anyway before I go to work or to bed. Anyway, I loaded up Assassin's Creed: Odyssey for a quick go before work and noticed that RTSS was reporting the driver as v416.16 rather than v416.34 (normally it shows the correct version even without restarting) so I exited the game and restarted my PC anyway. Driver seems to be fine with that game post-boot, running (unsurprisingly) exactly the same as with v416.16. However, I did disable then re-enable G-SYNC but only for Fullscreen this time rather than Fullscreen + Windowed. The reason for that is I've noticed some abnormal framerates usually in Unity Engine games such as Pathfinder: Kingmaker where the game can dip below 60 fps despite low CPU and GPU usuage. I wondered if G-SYNC was the issue here as I've seen countless reports of issues with G-SYNC and window mode yet NVIDIA seem to continue to ignore it. A couple of questions for people who use G-SYNC: 1. Do you disable then re-enable G-SYNC after every driver install (those like me who install over the top of the previous driver rather than do a clean install via the installer or DDU)? 2. Do you enable G-SYNC only for Fullscreen because of issues with borderless fullscreen (borderless windowed) games such as those that use Unity? I'm curious about this one because Unity, by default, tends to use borderless fullscreen and in a growing number of games that use that engine I've found I have had to force exclusive fullscreen via the -window-mode exclusive commandline in the game's launcher settings in order to get framerates that don't tank to sub-30 fps and stay there. It was a real annoyance a few months ago affecting games like Road Redemption, Dungeons 3 and other Unity engine games. 3. Just how useful is G-SYNC for borderless windowed games anyway? Last I read with that borderless window forces triple buffering and its own v-sync anyway so that might explain why games still run smoothly without G-SYNC in such games despite having variable framerates on a 165 Hz refresh. Anyway, the gist of it is: would I be better off just using G-SYNC with fullscreen only since Microsoft seem to continually break it (and NVIDIA don't seem to be able to fix it properly)? The Turbo button on my ASUS ROG Swift PG279Q monitor no longer works, thanks to Microsoft's meddling!!!
