I FOUND THE CAUSE OF THIS ON MY RIG:
The problem was caused by G-Sync. I had G-Sync enabled for windowed mode, which affects Roblox Studio since it is in windowed mode. As soon as I disabled G-Sync for windowed mode, and restarted Studio, then the FPS shot up to 60 FPS.
I’ve never had G-Sync and this is still a problem for me. Disabling V-Sync doesn’t help either.
You can’t disable VSync on Roblox
I’m also having this issue with studio and it seems that my CPU does not like any to do with DirectX11 or DirectX9. I made the switch to OpenGL and everything returned back to normal. Vulkan also had yielded the same results as OpenGL.
I was having the same issue, messed with some studio settings today and managed to fix this for my PC. All I did was go to Settings > Rendering and turn on FrameRateManager and change GraphicsMode from Automatic to OpenGL
Was getting about 37 FPS in play solo before, now getting a smooth 60 again
Seems like the performance issues I was getting has been resolved. Is anybody else having issues with this anymore?
Thanks dude this has solved it for now.
This does not work for me. The only way I can fix this is by putting my graphics mode to Direct3D9 which is absolutely horrendous quality. I cannot do anything cosmetic with it and this has been happening for months.
I’ve been posting in this thread but seeing as you guys think you’ve found a solution I figured I might as well make it known that this is still happening to me here.
It seems like OP’s issue has been resolved, so closing this thread in favor of another still-open duplicate bug report. Please post any similar issues you experience there.
