Severe lag spikes when moving the mouse in Studio

This is continuously going on so I would suggest fixing it quickly since it would get lots of downtime for Roblox studio users.

This has been happening for a while now.

I’m now experiencing this as well. I first noticed it happening while in Test mode and doing firstperson/shiftlock and then quickly looking around, but it doesn’t happen in thirdperson. It seems like it lags whenever the mouse is moving over the viewport as long as you aren’t clicking on anything. Very strange, and very aggravating.

Just experienced this today. From some research, it looks like this is related to the mouse input polling rate. Though, when I adjusted the polling rate switch on my gaming mouse, it didn’t seem to make a difference.

I also noticed that the camera controls were acting strange and erratic when panning in testing mode.

I was able to apply a temporary fix by switching to a different mouse, but this is not a long-term solution. The mouse worked just fine yesterday, and I did not install any new drivers.

Hopefully a fix will come out for this soon!

I’ve started to encounter this issue in studio test mode. It doesn’t seem to occur in solo mode though.

Something I neglected to mention is that this only happens in testing mode exclusively for me, as well.

This has also been happening to me recently after installing a new graphics card. Only happens in one game, and doesn’t lag if i hold down a mouse button or keep the mouse still. Only lags when i dont click any mouse buttons while moving.

In this video, i stop lagging whenever i hold down a mouse button, but when i release it my frames drop significantly.

Same thing happening here and it’s pretty annoying. I can’t find any good solutions for it. From an older forum post lowering mouse polling rate below 500Hz helped to the extent of moving the mouse around in studio with losing a lot of FPS, but when playtesting my game in Studio the lag persists and moving my mouse makes FPS go as low as 10…

Roblox please fix this

Hey, I actually experienced this “weird” camera effect as well! (Hopefully the same thing we’re both thinking about), for me personally it sometimes felt like either getting stuck or becoming higher sens… Just not moving where it should have.
I tried switching mouse too, but no luck. It seems on a laptop with a trackpad this issue doesn’t persist-

Sorry to necro but this issue still persists, any update on this matter? @thirdtakeonit

This issue is likely different to the one I reported.

The behaviour I reported happens consistently at an interval of about once per second and goes away if you click or right click whereas yours happens strictly when you are left clicking and it happens constantly instead of once per second. Your game is also probably doing some raycasts with the mouse so that’s likely related to the lag spikes you’re encountering.

This is how the workspace runs when all scripts are disabled:

Not sure if our issues are related but my code isn’t the cause. My issue only occurs in studio, and gets worse as more players are added to the local testing. Also the lag stops when i hold any key on my mouse, not just left click.

This has been happening to me for a while as well.

I’ve deleted all my plugins and disabled all plugins I’ve installed, and it doesnt help fix the issue. It goes away on its own sometimes.

Can confirm this is happening to me lately as well, for some weird reason its only specific to Team test and Local Server instances.

Particularly nasty case here:

I tried shutting off my pc as well, didnt make a difference.

I’ve noticed I’m getting framerate drops in studio when moving the mouse as well

Can confirm this issue is happening to me. On my M1 Max, FPS drops consistently while moving the mouse. It seems to improve when closing any docked windows in Studio. On my Windows desktop, there is no issue. I’ve been trying to debug my game for the past hour looking for performance issues - it turns out this is on Roblox’s end.

Interesting to note: Holding down left or right click makes this issue not happen while moving the mouse:

Running into a variation of this bug as well, any action that I do is delayed randomly. Even transfers to moving simple windows across my desktop. Only started today.
