INSANE sudden lag when scaling, adding/deleting, or duplicating parts

Hello,

I was trying to scale a new part to do a quick measurement on the distance between the floor and the bottom of a window when all of a sudden I began to lag like CRAZY (frozen for a good 4 seconds) when doing so and even some slight scaling can still cause this lag. I also figured out that when you try to choose a plugin, duplicate a part, delete a part, or add a new part, the same issue happens. However, it doesn’t act this way when using the other tools that manipulate parts. Despite the pretty large size of my game, I have never experienced something like this in the past year and half of development. I’m so stressed out as I can’t really do anything like this and it’s holding me back so much. I was wondering if anyone has any type of a solution for this problem as it would be GREATLY appreciated!

BEFORE YOU DO THIS, PLEASE READ UP ON THE NEGATIVE EFFECTS IT CAN CAUSE. I’d suggest that you enable StreamingEnabled. This usually helps with a lot of lag issues. It can cause quite a lot of physics issues.

Alternatively, if you’re using terrain then get rid of some of the excess that will lurk under the map - where players cannot see. If its a RAM issue then change the priority of ROBLOX Studio. However, if you’re using Free Models then I’d suggest you remove them and replace them with your personal models. There are a lot of variables, plugins etc etc.

If you would like a guide on changing priority please reply accordingly.

Already have StreamingEnabled on.

I do use terrain but no insane amount of is lurking in the parts where players wouldn’t be able to get to.

I feel like it could have something to do with this as my computer has been pretty slow for a while now and also isn’t the greatest, once again though this issue was something sudden while working on my game like normal as I do everyday.

I’m pretty sure free models/meshes have nothing to do with this. I’ve used props and such in my game and have never ran into any issues, I tend to be pretty cautious too when I do need to use something from the toolbox, so it’s unlikely that this is the result of simply “using a free model”.

I have quite a few plugins but all of them are the essentials.

I wouldn’t mind hearing more on this.

Again though, all of this happened suddenly. Things were performing perfectly fine seconds prior to when this issue came up. All of a sudden got crazy lag when I scaled again.

This sounds like other posts that had similar issues, and it was usually caused by a humanoid or its parts left behind unknowingly somewhere in the workspace.

Try to click on the rigging plugin, or search your workspace for unintended dummies. Also, try to exit studio and log back in obviously too.

If all this doesnt work, try to disable all plugins, and re-enable them one at a time to find the culprit.

Yeah I read about that too but there’s no Humanoid in Workspace for me, only in dummies and models and such.

Done this, restarting computer, AND uninstalling/reinstalling Roblox Studio and nothing has changed or been fixed unfortunately.

I don’t think it would really make a difference as there’s also other things which mentioned mysteriously causing this sudden lag as well.

Does this happen in an empty baseplate?

Nope, the issues obviously disappeared in a much smaller game but am still not so sure why my larger one all of a sudden began acting like this if it’s never lagged to this extent, especially when manipulating parts like scaling them.

So the lag is narrowed down to new parts and elements, not existing ones? If so, have you maybe accidentally switched your tool mode to Physical (from Geometric)?

Hello,

Have you tried putting your current game into a fresh baseplate server?

Nope, I don’t think moving the game to a different one would make any difference either. I have terrain in the game also which you can’t import to other games from what I’ve seen and don’t feel like remaking it.

No like it lags with everything except rotating and moving parts. When you scale, add/remove parts, select a Camera Light plugin I got, it freezes for a good 4 seconds before you notice the part scaling up slowly with the lag. I thought it was my computer at first but things work fine when scaling in other games. I’m not sure what my bigger game might have or what are common causes of this insane lag since it’s never happened before in the game.

Yeah I’m running into the exact same lag issue except no Humanoid in Workspace.

Sometimes a scaling issue means the part you are scaling has another part far away from it that it is including with it, and so only the scaling is affected because it tries to scale the two (or more) parts across a large distance.

I once used a camera plugin i wont name it… that would create a part to be used as the camera. Even after reverting the cutscene, the part was left behind. The plugin didnt handle reverting all that well. The new part caused issues and lag for me until i found it and deleted it. My point being that plugins help but can also cause issues like that sometimes. I would disable the plugin that shows lag for you just to test it.

It is not an easy thing to solve and is very frustrating so i sympathize with you.

Just an fyi, there is a plugin (i havent used, but heard of) that does copy and move all your terrain with one click, in case you need to move to a fresh baseplate but that is a last resort.

So I tried deleting the entire little house I’ve been making a detailed interior for lately to see if that was the problem and yup, there’s too many assets in a relatively small area and I’ll have to optimize it a bit. Thank you so much for the help though!

Depending on whether this is still relevant - if you right click ROBLOX Studio on Task Manager, go to details, right click it again, set priority = high. I wouldn’t advise going over high.

I had the same trouble, the issue is because you have an humanoid inside workspace, as soon as I removed it, everything stopped lagging.

Yeah it wasn’t a humanoid when I was experiencing this, turned out a 3d model I had in my game was absolutely KILLING performance. Deleted it and everything all good now.

What’re your PC specs? And what’s the age of the PC? Are all your drivers updated? Could be hardware/software issues, Roblox Studio bug, or a combination of them all.

Hope things work out for ya!

How can u leave a humanoid in the workspace? Do you mean a dummy? I’m curious?

I solved this a long time ago lol, someone just bumped my thread.
