Issue with GSync and SLI

[OC40]

Hello guys.

 

Okay, so backstory. It started about 3 days ago when windows decided to update to Windows anniversary edition. The update seemed fine until I decided to play borderlands, then doom, then even civ V. All of these games ran over the 144 frames per second limit set by my ROG Swift PG278Q monitor. I then went into the nvidia control panel, re-enabled gSync (since it was disabled), re-enabled my SLI (to maximize 3D Performance) but gSync still didn't seem to want to work. I was using drivers 372.90 at the time.

So I then uninstalled windows A.E and disabled windows update in services and everything went back to working fine until today. The little red light in the bottom right hand side of my monitor is now permanently red unless i disable gSync completely. Everything has gone back to not working.

 

I have tried disabling sli and gSync and re-enabling them, this has not worked. I have tried a clean installation of my drivers, and backdating my drivers to 372.(54?), this has not worked either. I cannot remove a card from my system as both 1080s are watercooled. Unless vSync is enabled, the frame rate seems to go limitless. And gSync feels much, much smoother then vSync.

 

Nothing I have tried has worked. Attached are screenshots from the nvidia control panel. And yes, the gSync monitor is set as my primary monitor.

 

Thanks in advance.

G-Sync is V-Sync, as far as games is concerned.

So turn them both on and you should be back to making use of G-Sync.

Really? Borderlands stopped working before I even touched it's vSync settings. When vSync in borderlands is on yet framerate in the game is set to unlimited and my monitor is set to 144Hz the game will go well over that 144 fps limit. framerate was set to unlimited before with vSync on and it worked fine at 144 fps, yet framerate on borderlands does not have a 144 fps option, only a 120 fps option. And that feels choppy, which suggests to me that gSync isn't working.

Oh and - gSync on borderlands works fine while the game is in windowed mode and not fullscreen. Has anyone else here got borderlands and can test gSync? I think it may be a game-related issue.

I run into this problem when benchmarking, if V-Sync is on in Nvidia Panel, it overwrites anything else and caps the benchmarks to whatever my monitor is set to.

So V-Sync on in Nvidia Panel first (both global and program/game), then in-game.

.So you want me to turn vSync on in my control panel and in games?

Yes. It needs to be on in all places, for some strange reason.

Never mind, a total reinstall of the operating system has worked.

 

By the way and I know this is sort of off topic - 

for two GTX 1080s (oc 2050MHz each) and a 5960X (OC 4.7GHz, perma 4.7 no turbo/fluctuations) with a 480mm (60mm thick) and a 360mm (60mm thick) all EKWB extreme radiators are the following temperatures good:

GPU 1: 32C (idle) 49C (load)

GPU 2: 32C (idle) 47C (load)

CPU: 40C (idle) 56C (load)
