Freesync stutters

Message Topic Search Topic Options Post Reply Create New Topic Printable Version

   I have an ASUS ProArt PA278QV which is supposed to support a Freesync range of 48~75Hz. I've noticed that the closer I get to 50fps the more stutters I'm seeing. Anywhere between 60-75fps is smooth but once I start dropping below 60 the stutters start appearing.

My specific use case is a Commodore Amiga emulator running in Retroarch. It's a 50hz PAL machine so 50fps is required for smooth scrolling. Other emulators that require 60hz NTSC are perfectly smooth. Normal PC games are also smooth. Though I did an experiment and limited the framerate to 50fps, I saw the same stutters.

Frametime graphs are level. My PC isn't stressed either. Is it possible my monitor just doesn't have a good Freesync implementation? It seems the closer to 50hz I get the more stutters I see.

	I'm not too familiar with Freesync, but I've been using G-Sync for many years. G-Sync has to be setup just right for it to work properly, and it's easy to get it wrong. I wonder if your Freesync just isn't setup properly. Here is an article that might help: https://www.amd.com/en/support/kb/faq/dh-013
