Refresh rate drops when using GSync

Any update on this?Having same issue .Getting 25-30fps
Intel i9 9900K
Asus ROG STRIX RTX 2080 Ti 11gb
Asus ROG Maximus XI Hero motherboard
Acer Predator 165hz G-Sync monitor

Hi @Sankeerth_Parimi,

We haven’t made any changes here, but our recommendation for now is to disable G-Sync for non-fullscreen apps. This should resolve things for you.

Hi guys, had identical issue. Instead of changing G-SYNC settings globally you can adjust for Roon itself.

Right click desktop > NVIDIA Control Panel > Manage 3D Settings > Program Settings > Roon > Monitor technology changed from G-SYNC to Fixed Refresh Rate.

Went from stuttery to smooth and running properly


This is fantastic. Thank you so much!

Thank you Guy_Pearce, this solved my problem as well!
I’m running an i9 9900k @5.1 Ghz, GTX 1070 and 32GB of RAM and was breaking my head over this. When disabling G-Sync from my Predator X34A for the Roon application specifically I get a steady 100fps instead of 15-30… Don’t know why it was doing this but hey it’s solved now :slight_smile:

Can confirm this is still an issue in Roon 1.8.

Roon is running at 15 FPS and not configuring itself properly in the Nvidia driver. As in not telling the driver that Roon should run at a fixed refresh rate to avoid flicker at 15 Hz.

Nvidia provides NVAPI for this which allows access to all driver settings. It’s the API Nvidia Control Panel itself uses.

Roon should use it to make itself not flicker because for the average user it is non-trivial to figure out why their display suddenly looks broken whenever they use Roon. I first thought the backlight in my monitor was dying because I noticed a faint strobing at the bottom of the screen. It was not at all obvious that it is a framerate issue that only happened when the Roon desktop app was in focus.
Once I turned on the FPS counter of the Geforce Experience overlay it was clear what was happening and I then found this thread that perfectly describes the issue and a workaround. But that’s a lot of technical deduction and searching. For some users it might just be one of “I think my monitor has an issue” or “I guess this Roon app just flickers”.

Still I think if Roon is making use of GPU hardware acceleration it is also responsible for properly configuring itself. Which imo it does not.
