Funny enough, the only way I can get gsync to actually work in DX12 games is to NOT run them in “proper full screen”. If I change my gsync setting in NVCP to “windowed and full screen mode”, then set my games to windowed (NOT borderless windowed, that doesn’t work), gsync works. Full screen or borderless windowed DX12 = no worky.
I’ll do a full driver uninstall when Nvidia releases a new one (as I normally do). Not wasting my time otherwise, because I guarantee you it won’t fix anything.
My g-sync monitor states if g-sync is enabled in the monitor’s menu.
There’s also an option in Nvidia Control Panel to show if g-sync is working. It’s called ‘G-SYNC Indicator’. It’s located under ‘Display’ in menu bar up top. File / Edit / Display / Help.
I can tell right away it is working because of the lack of screen tearing and smoothness. That sucks that it is not working for you. It is not liking your configuration for some reason. I do not use G-Sync in windowed mode at all. I have it only for fullscreen.
It seems something is going on with DX12 these days. DX12 works for me for a while and then becomes unplayable within a few hours. Right now I’m using DX11 FFR on and I get maybe 100fps avg.
Oh, wow, didn’t know about that, thanks for the tip! Bit of an annoying overlay to have on, but neat feature. My monitor says g-sync is enabled, but it says ON even if it’s not working, which you can clearly tell by the refresh rate showing 165hz no matter what.
Ok, here’s the FIX!
I did a clean install of the 417.58 hotfix drivers, which did absolutely nothing except waste my time.
Then I came across the thread on Nvidia’s forums about the 1803 update breaking gsync in windowed mode, or something like that. I had previously ignored it since it was from April, and I don’t care about windowed mode, but the thread is still going, and one of the most recent posts mentioned turning off his second monitor and rebooting.
So I did somewhat similar. I straight up unplugged my second monitor, and rebooted for good measure. After rebooting, my gsync monitor has reverted to 60hz in NVCP for some reason. Set it back to 165hz, fired up BF5, and like magic, gsync was working in DX12 again. Not sure what broke it in the first place, or why Windows and/or Nvidia drivers are so buggy that this fixed it, but whatever. Hopefully it doesn’t revert back to being broken the first time I swap primary displays around to game on my 4k monitor.
If I unplug my second monitor and restart the PC, seems to work… And continue to work when I plug the second monitor back in. Definitely an issue that should be fixed…
You assume it’s working? Jeez. When I pay a significant premium for something, I like to know if it’s actually working or not… And gsync not working wouldn’t cause any “weird frame rate issues”, so it seems you don’t even understand what you own.
Did you try to unplug, reboot, double check all your settings in NVCP, then load up BF5?
Maybe, just maybe, one day, Microsoft will get their together. Until then, we’re stuck suffering with stuff like this.
I also find it absolutely hilarious that people are up in arms about how “gsync doesn’t work with SLI” and “gsync + SLI has been broken for months” because some no-name website posted an article showing that gsync + SLI results in slightly worse SLI scaling in certain games. But yet real issues like this gsync not working in DX12 fiasco exist, and you don’t hear a peep about it from the anti-nvidia keyboard warriors of the internet.
I have same problem.My monitor is Acer Predator xb271hu.Gsync in this game just not working properly anymore.I have microstutering or what this is on 80fps lol.I tryed with DX11 or DX12 unplug my second monitor and didn’t help nothing.It’s just broken game I can’t play this game like that lol.I have no problems 14 days ago with same settings and game has running very smoothly 70-110fps on GTX 1070 +I7 4770K.I other games i have no problems.BF1 runs great and bf4 runs even better with gsync
It’s odd because I only updated my NVIDIA driver (the one from I believe Dec-12) yesterday and then today noticed this exact issue. But I was playing in DX11 not DX12. Two reboots did not change it. I was just locked at getting no more than 60 FPS in the display in-game, although occasionally it would go up in the menus.
But - when I switched to DX12 and restarted, it’s working fine now.
So I am suggesting maybe the mode may not matter, but switching modes at least temporarily fixes this.
I was able to get it working in windowed mode as well, but still holds that the dual monitor dealio worked for me. If you guys don’t have dual monitors and are having this issue, that is unfortunate as I don’t think we have a work around to that yet… Since I had this issue in Tomb Raider as well, I doubt its BF V, either a windows issue or an nviida driver issue. I think I lean towards windows.
For me gsync not working in fullscreen,windowed or borderless mode in BF5.I have same microstuters or what this is.For example in the latest Tomb Raider gsync works smoothly on ultra even with 55fps and BF5 lags with 80fps lol
This is releted with servers.They had broken servers i think
I think it’s Windows related, or at least a Windows/Nvidia driver interaction related issue.
I’ve switched between my 1440p gsync display and my 4k non-gsync display as primary monitor a couple times and gsync continues to work in DX12 without a hitch.
BUT, the first time I tried turning my gsync display OFF while using the 4k display as my primary, gsync was broken as soon as I went back to the gsync display as primary and loaded up BF5.
I don’t understand why, but when I turn my gsync display OFF, my remaining display will flicker momentarily, Windows will make a noise like I just unplugged a device, and the gsync display will disappear from my “Windows Display Settings” screen. Basically with the gsync display turned off, but plugged in, Windows acts like there is only 1 monitor plugged in. Then when I turn it back on, my other display will flicker again, Windows will make a noise like I just plugged in a new device, and I’ll get a popup notification saying something like “gsync display connected, click here to configure”. Clicking that will open up NVCP.
It seems that whatever happens when I power the gsync display off and Windows thinks it disappears, is what screws up the functionality of gsync in DX12.
