As a Roblox developer, it is difficult to use studio with Monitors that have Free-sync/G-sync as a built in feature. I can’t speak for each and every setup but I have to ritualistically turn off Free-Sync manually on my monitor before working in studio since it renders it slow and unusable.
If Roblox is able to remedy this, it would be a great quality of life service since our field often has Developers in and out of games and applications that utilize G-Sync and similar technology.
This sounds similar to my bug report here. It may not be the exact same issue you’re experiencing but it might help provide some insight on how to work around it. Personally, I’d suggest adding an exception for roblox studio in Nvidia Control Panel and setting Monitor Technology to “Fixed Refresh.” You’ll have to redo this any time roblox studio updates or you update your graphics drivers but it is a better work-around than disabling it on your monitor every time. Cheers!
