Having a similar problem as well, although my entire studio lags, like camera movement and stuff. Any script I open lags, despite the number of lines.
Running a beefy 1080 Ti with lots of system RAM so I highly doubt it’s an issue on my end. Odd.

I have the same exact issue, but my script is only 5k lines long.
Found any fixes?

Nope its an internal bug, I don’t think there is much we can do. The only real “solution” is to split it up into multiple scripts and try to follow the D.R.Y rule to minimize the amount of code.
Aww…
What if I used Rojo? Would another script editor fix this issue?
Yea, 3rd party script editors can handle 10s of thousands of lines of code.
Still having this issue, and many of the previous fixes mentioned (like disabling G-Sync) didn’t work. Only thing I tried that worked was the idea of popping the script out of the main window. Is there a more permanent fix than that yet?

I have the same issue.
The way I dealt with it was pulling it out of the window.
But now for me studio its self is lagging and it’s getting worse. I can not build now.
This all keeps worsening after updates.

I’m just now experiencing this issue, but disabling G-sync seemed to work for me. Why does G-sync not cooperate with script editor??
Not sure why but this only happened to me after I added “.Parent”
(Update: turned out it also start lagging no matter what I typed after the dot, also replacing the second line with a comment stop the editor from lagging
I know its been a while but this still works.
I am having this issue with my 27K line script… roblox studio takes about 20-30 seconds to type anything making it almost impossible to work on at this point I am going to have to use note pad to edit it… and recent updates have only made it worse. If this could be fixed that would be nice.
This has been a problem for a while now. Definitely on FreeSync at least.
i think it’s lagging just because its so many lines… very bad practise to have so many liens in one script… consider using modules 
yes I have considered it, and might have too at this point I just need to learn more on how they work before I can try and use them.
This is still an issue. The script editor will lag even on brand new scripts with as few as 100 lines unless I move the editor until it becomes a subwindow.
My system:
Windows 10 Pro
Ryzen 7 2700X
Radeon 580X
64 GB Ram
Hate to bump this but I have the same issue. I have seen a thread with issues with Team Create but I doubt that is it, I’ve just recently had this issue. Popping out the window doesn’t work, neither does disabling G-Sync.
Specs:
Windows 10 Pro
Intel i5-9400F
GeForce GTX 1060 6GB
16GB RAM
I hope this issue gets fixed soon. I’ve tried setting up Rojo but never figured out how. I’ve had scripts with 20 lines lag, CPU usage doesn’t move either.
Script editor is still lagging. Only working solution is to move the editor window into its own sub window. Please fix this.

Just encountered this issue, when I open any script (empty or not) my FPS instantly drops to around 3 FPS.
I have just changed out my GPU from an RX 590 to the RTX 3080 and this is when the issues started to occur.
I’m running on the 64 bit version of Studio and I have Nvidia G-Sync enabled.
System Specs:
CPU: Ryzen 9 3900X
GPU: RTX 3080
RAM: 16 GB 3200MHz CL 16
Note: Managed to solve the issue. I uninstalled the most recent Nvidia drivers and installed the previous one (at the time 457.51) and I also disabled G-Sync if a window wasn’t fullscreen.
Okay, I seem to have found a solution that works for myself.
1] Uninstall Roblox
2] Remove the roblox folder from appdata/local
3] Purge all roblox entries from your registry. (If you don’t know how to edit the registry safely, do not even try.)
End result: I gotta redo all my settings but it seems to have worked.
I’ma be experimenting to see what was causing the severe lag, but I believe it may have to do with me keeping my save folder stored on a second hard drive, rather than filling up my NVME drive with files.
Theory about multiple drives interacting didn’t change anything, studio still runs like a charm now. My best guess is something in the registry got corrupted, but exactly how I’m not sure.
Either way, doing a full reinstall including the registry entries has completely solved everything for me.
