Roblox studio/player taking 100 percent CPU usage?

Does anyone have the issue where roblox uses 100 percent cpu usage? Everytime I open studio or Roblox player, it lags, and in task manager it shows 100 percent.

I’m currently having this problem and unable to play ROBLOX on my Gaming Laptop with fine internet – I’ve tried reinstalling, restarting, looking for CPU eating viruses, and nothing has worked to solve this problem. I cannot play on any graphics setting the lag is equal. This happens on all games and it started overnight.

Also, my roblox sice 10/28/2022 is now crashing every time, I play a game.

I think Roblox is using your processor’s integrated graphics.


This never happened before.

Do you have a discrete graphics card? If your processor is quite old, its normal for even Roblox to take whole.

My computer is 2 year old and no changes at all…

And my processor is Intel i5

Can you send your PC specs here?
