nvidia driver - stuttering / audio lag

Im using ubuntu 20.04 lts with nvidia 465.27. recently i realized that my gaming performance is awful. I mainly play OSU and audio delay with stuttering is insane. there is no problem on other parts of the laptop. i can't use nvidiXsettings app. it straight up shows me prime profiles. and i cant use nvidia-smi command. I tried fixing both of them via google but i just couldn't do it without another hand of help. i also tried removing-reinstalling the nvidia driver. still didn't work.

lspci | grep -i --color 'vga\|3d\|2d'
00:02.0 VGA compatible controller: Intel Corporation UHD Graphics 620 (rev 07)
01:00.0 3D controller: NVIDIA Corporation GM108M [GeForce MX130] (rev ff)

and

nvidia-smi
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

.

sudo nvidia-settings
ERROR: NVIDIA driver is not loaded

Maybe you should go back to the 460 driver. You can go to "software and updates" menu and select the option nvidia-driver-460.

I have the same gpu as you, and using this driver everything is working fine.
