Refresh rate drops to 20/30hz, every other app/game runs great

[Glen Harding]

My refresh rate is fluctuating between 20 & 30hz every few seconds when using Affinity Designer, I have no files open when this happens. I recently upgraded my GPU from a 1080Ti to a 3080, Affinity Designer was running perfectly before this upgrade, this is now the only application I'm having this issue with. One other program had the same issue and disabling Hardware Acceleration in the program settings fixed this for me, I have disabled Hardware Acceleration in the Affinity Designer preferences but I'm still getting low refresh rate - I've tried reinstalling & updating to the latest version, still no luck - any help is much appreciated.

Thanks.

Hi Glen,

Welcome to the forums

Do you have a HDR monitor? If so does disabling HDR cause the app to run at the correct refresh rate?

Thanks

Hi @Callum

Thanks for the response, no I don't have a HDR monitor.

This issue only started happening after upgrading my GPU, it was working perfectly beforehand - this is the only thing that has changed.

I had the same issue in another unrelated application, disabling Hardware Acceleration (for Windows & the application) fixed it but unfortunately not for Affinity Designer.

Kind regards,

Glen

----FIXED----

Updated in case anyone else has this issue in the future.

I've managed to fix the issue by changing my G-SYNC settings in the NVIDIA control panel (see screenshot).

For whatever reason, having G-SYNC enabled for windowed and full screen mode causes low refresh rate on this application, CCleaner & Norton Security - changing G-SYNC to full screen mode only fixes the issue.
