Over the weekend I ran into the bug in Studio. I apparently had forgotten to turn off the G-Sync windowed mode setting.
I was able to resolve it by turning off the setting and restarting Studio.
I’ve done some quick google searches and it seems like this applies to other games, so I’m guessing this is a bug on Nvidia’s part. Some of the games which apparently hit the same issue (all of which are using different game engines):
- Final Fantasy X Remastered
- Fallout 4
- Battlefield 3
- Diablo 3
- Heroes of the Storm
I also tried opening the microprofiler while I was hitting the issue.
Present was taking 42 milliseconds, which is consistent with the graphics driver limiting us to 24 fps, rather than something in the Roblox engine itself.
Unless there’s something we can do on our end, it seems like it’s up to Nvidia to fix this. The good news is that the setting can be turned off without doing any harm, and it’s not enabled by default.
