This lag also occurs under different circumstances but this is the most intrusive one.
When I open Roblox Studio everything behaves as expected until I open a script.
When I open a script, Studio’s frame rate drops to something like 2-5 fps making it impossible to code.
The only workaround I have found has been to undock the script window so the game view is no longer covered. I often elect to place it on my second monitor (though I would much prefer it remain docked over the game view). Once I do this, performance returns to normal.
This happens in existing places, and brand new, unmodified place files.
As for the other times this lag occurs as I mentioned above, sometimes after clicking ‘Play Solo’ and then stopping the test, Studio will lag until I focus the Toolbox by clicking its title or somewhere inside of it.
This lag doesn’t affect the rest of my system, just Roblox. It’s also worth noting that while Studio is lagging for either of these reasons and I click another window like Spotify or my desktop, Studio will return to normal performance, even with a script docked over the game view.
This lag makes using Studio very difficult and I’ve noticed a few similar (but not the same) topics around the forums about people experiencing this lag but from different causes (like someone wasn’t having the script open version but would lag constantly if he interacted with the Toolbox or Terrain Editor).
Here is a video of it happening:
I am more than happy to give any debug files needed.
What I’ve done to try and troubleshoot the problem:
I have uninstalled Roblox Studio, deleted its AppData folder (AppData\Local\Roblox), deleted rbxcsettings.rbx in AppData\LocalLow, reinstalled Studio, and watched the lag continue.
I’ve opened blank project files and still seen them lagging when I follow the repro steps above.
I’ve ensured I had no plugins running and still lagged.
I’ve tested on my laptop but didn’t get the same problems.
My system specs are:
Processor: AMD Ryzen 7 2700X 8 core
Graphics: EVGA 1070ti TFW
Ram: 16 GB
Storage: Roblox is installed on a Samsung SSD
I will send log files to the place you send log files and link back here.
I am open to helping in any way. I need Studio to be working smoothly again.
Edit: I also talked a bit about this problem here:
After disabling G-Sync in the Nvidia control panel and then restarting Studio the lag entirely disappeared which is amazing! I tried re-enabling G-Sync and restarting Studio again to show my brother how bad the lag was and it returned so this solution is repeatable! Thank you so much!
I would like to have G-Sync enabled so it would be nice if this could be sorted out but I’m more than happy with this workaround as it means I can go back to using Studio normally.
I was worried no one would answer and my question would be ignored so thank you for responding and helping.
I’m going to go use Studio for an extended session and I’ll come back here if the lag comes back but if you don’t hear from me again that means it’s gone for good, so thank you!
If it’s not already selected, select the tab on the left titled ‘Set up G-SYNC’
Then uncheck the property ‘Enable G-SYNC, G-SYNC Compatible’
A ‘Apply’ button should then appear in the bottom right of the window. Click it.
Restart Roblox Studio for changes to take effect.
If you don’t see a G-Sync related tab on the left as I do then you probably don’t have a monitor that supports it so you don’t have to worry about it being enabled, and the lag is probably coming from something else.
If you have an AMD graphics card or are using integrated graphics on an AMD CPU then you won’t have the Nvidia control panel and will need to look up how to disable FreeSync.
Can vouch on the problem, but there’s far more than that.
This is surely not a device performance issue as even bigger games outside of the platform work absolutely flawless.
This is a cricital issue; whether they’re scripts, rotating the camera, interacting with Explorer, publishing the game, etc. Many people are experiencing this, this needs a fix ASAP.
G-Sync or Free-Sync depending on if you have an Nvidia graphics card or an AMD one.
I described how to disable G-Sync in my post above. You might have to Google how to disable Free-Sync if you’re using an AMD graphics card or integrated graphics.
