Running experience, then stopping the same experience will cause FPS to drop dramatically

Bug Reports Studio Bugs
#1

Reproduction Steps

Open any experience in Studio and hit run, or play, FPS will be fine, but once stop is hit to go back to editor, Studio will drop to around 5-10 FPS depending.
video – bug - YouTube – defaulted to low resolution because of bug, excuse the blur.

My specs can handle other bigger titles at higher FPS, so it isn’t a hardware issue
Specs –
Ryzen 5 5600x
Radeon RX 6600 8GB
8GB RAM

Windows 11 - installed onto an M.2 SSD, Studio and the Roblox Client are installed there as well.

Expected Behavior

To have consistent FPS between Play and Edit.

Actual Behavior

FPS gets really bad when hitting stop, making working on an experience a chore.

I’m also experiencing this pretty much every time I either playtest the game or toggle the animation editor, amongst other things I haven’t caught an eye on yet. It’s making developing really difficult on my end.

It has gotten so bad where my FPS will drop to 1 at some points, hopefully Roblox can look into it.

I had this issue before, but I solved it by changing my G-Sync mode to Fullscreen instead of Windowed. I’m not sure how you would do this on a Radeon, but I’m sure they have their own setting for this.

Just started running into this issue after the recent update.

It seems based on what a few of my friends have said that changing the rendering helps, which is odd. I also want to note this stopped happening after upgrading from Windows 10, and seems fine, will keep updates on what might be the case.

Ive been told it mostly happens on the Vulkan rendering option

The update…

That recent update fixed meshes being a descendant of a humanoid model, but also broke the FPS system I was making. I also believe the update contained many fixes for BillboardGui and an issue with lighting technology, which I believe to be the only related issue.

I didn’t encounter this at all on my desktop PC, but I haven’t tested it on my laptop. All I know is that the mesh issue was fixed and that the FPS system broke because of it, and I wouldn’t say either are related.

This was probably because one of your GPU drivers didn’t update on your previous version, and one of those updates applied a fix to this.

i switched to d3d11, it doesnt happen anymore ty

#9

Meant from 10 to 11, any difference between that?

#10

No, actually. I guess when you upgraded something changed that I’m not aware of, probably one of the configurations for Roblox.

#11

This happens to me as well, although the fix on my end was to completely disable any G-Sync related settings.

#12

Weird. I thought there might be a feature to blacklist certain apps from G-Sync, since I think it’s required for higher monitor refresh rates (for certain apps).

#13

Thanks for the report. I filed a ticket to our internal database.

Closing this one out as we don’t have a reliable way to reproduce. If there’s still someone experiencing this and you have a repro, please update this thread and we can investigate.
