SYNC FAILURE: Unable to VSYNC.

Post by perilla12 » 04 Feb 2024, 00:33

I am getting some problems with the test. I dont know what happend, i did it time ago and it worked good. Sometimes im getting the warning sync failure and sometimes im getting the performance error and my fps are not getting in to 240. It only happends to me when i using 240hz test. I have an rtx 4090 and ryzen 9 7950x3d so i dont know whats going on here...

Reboot, close all applications that might be starting with Windows (Discord, Skype, Afterburner/RTSS, RGB lighting control software, etc.) Only leave one tab open in the browser.

Can you provide a screenshot of https://www.testufo.com/animation-time-graph ?

Sometimes the pattern of that graph, helps me identify the culprit.

Try running single-monitor mode, since multiple different-Hz monitors will create major problems with TestUFO (and sometimes your games too!).
