Hello Debian community, Whenever I enable vertical sync in any one of various video games (including, but not limited to, Rise of the Tomb Raider, Team Fortress 2, Minecraft Java Edition & Hollow Knight), framerates frequently drop to between around 30 to 50 frames per second*. This occurs even if minimum framerates prior to enabling vertical sync exceeded the refresh rate of my display. Disabling Freesync in my monitor's built-in settings menu does not resolve this issue.

In the other games listed, I perceived the stuttering while playing. Any insight/suggestions would be appreciated. Best, flavonol
