Ok, I am home now so I can actually compile a proper response.
For clarification.
- I have reverted NVCP to default.
I have disabled Game Bar and DVR.
I have enabled Game Mode.
All background resources have been closed via task manager. (Aura lighting software, Logitech speaker lighting software, Steelseries KB&M lighting software. The only thing running in Windows during these tests are Afterburner and RTSS).
In game graphical settings are all at Mythical and I am running at 3440x1440.
To test I am booting into an outpost and running around it for 5 minutes. Note: some outposts are more resource hungry than others (plunder outpost for example), also weather will play into it. This will explain some of the min frame rate results.
G-Sync: Off - V-Sync: Off (In Game and in NVCP) - Max FPS 117, Min FPS 111, AVG FPS 116 - Apart from the full screen tearing it runs well.
G-Sync: Enabled (for windows & full screen) - V-Sync: Off (In Game and in NVCP) - Max FPS 117, Min FPS 97, AVG FPS 108 - Apart from the small amount of tearing at the bottom of the screen it runs well.
G-Sync: Off - V-Sync: Enabled (Disabled in game and enabled In NVCP) - Max FPS 117, Min FPS 60, AVG FPS 65 - Double frame buffer setting in game but V-Sync in game was off. Basically unplayable. Constantly bounced between 60-117 but mostly around 60s/70s.
G-Sync: Off - V-Sync: Enabled (Enabled in game w/double buffer and let 3D application decide In NVCP) - Max FPS 117, Min FPS 60, AVG FPS 65 - Basically unplayable. Constantly bounced between 60-117 but mostly around 60s/70s.
G-Sync: On - V-Sync: Enabled (Enabled in game w/ double buffer and let 3D application decide In NVCP) - Max FPS 117, Min FPS 80, AVG FPS 110 - Basically perfect except for 4 drops in 5 minutes to 80fps for a split second. Even when sitting still like in the previous video I posted. Constantly bounced between 105-117 but just those random interrupts where the frame times spiked.
G-Sync: On - V-Sync: Enabled (Enabled in game w/ triple buffer and let 3D application decide In NVCP) - Max FPS 117, Min FPS 103, AVG FPS 114 - Seems to run perfect.
G-Sync: On - V-Sync: Enabled (Disabled in game w/ double buffer and enabled In NVCP) - Max FPS 117, Min FPS 60, AVG FPS 110 - Runs terribly, it will be fine for a while then I will get sudden drops to 60fps for a second or two. This happened 10 times in about 9 minutes (ended up spawning on an island with a boat at it, so went for some PVP, love this game btw.)
Basically this was the same as the video I posted.
G-Sync: On - V-Sync: Enabled (Disabled in game w/ triple buffer and enabled In NVCP) - Max FPS 117, Min FPS 104, AVG FPS 115 - Seems to run perfect.
Every time I tested with G-Sync on I was playing in full screen and had the notification.
Bonus Test @ 100fps cap
G-Sync: On - V-Sync: Enabled (Disabled in game w/ double buffer and enabled In NVCP) - Max FPS 100, Min FPS 60 - Runs terribly, it will be fine for a while then I will get sudden drops to 60fps for a second or two. This happened 4 times in about 2 minutes. Same as if I was running at 117fps
