Random lag spikes and FPS drops for no apparent reason

[robloxamanwill (AmanLovesCats)]

For the past month I have been suffering from frame drops in roblox only, even basic and simple games get frame drops which shouldn’t be possible for my computer:
Specs:
Win 11
ryzen 5 5600H
16gb ram
512GB SSD+1TB HDD
GTX 1650 4GB graphics card

I run very graphic intense games on my setup outside of roblox and they work very well. I tried updating the drivers and lowering graphics but nothing works. It doesn’t matter if I cap fps to 60 or uncap it to 240 the results are same.

Is anyone else experiencing this issue, or is it just me? if anyone has any possible fixes, I would greatly appreciate it if you could comment them.

Edit: It seems the roblox studio acts the same, with constant frame drops and lags while editing which seems weird. I also used it for like 10 minutes or so before it started getting spikes.

Edit 2(8/10/25): It seems that anytime I open a roblox application the CPU temperature sky-rockets to 99 degrees C from average 50 in less than a second of the application opening. This does not occur with any other big applications.

How long do you keep a singular instance of the roblox client open? (NOT STUDIO)

If you use a singular instance for a long time (3 hours+), your best bet is to close and reopen roblox.

They are freshly opened instances. I don’t play a game longer than an hour at a go so this shouldn’t really be a concern for me.
