Glitches and Tearing on EOS-nvidia-wayland

[Pepan]

Hi,
I use nvidia gt1030 and a non-free driver. It works, but the image jerks a lot, especially over xwayland. When I hover the mouse to the top left corner, cones with tearing appear many times. When I try the same with Cachyos, the conks only appear once without tearing. Lots of other things work much more smoothly. How to modify Eos with nvidia to make it work as smoothly as Nvidia/CachyOs?

Which driver is cachyos using for nvidia?

Also, are you using Wayland on both EOS and CachyOS?

[Pepan]

Yes Nvidia version 555.28.02 and Wayland are exactly the same on EOS and CachyOS

Have you read these tips? https://wiki.archlinux.org/title/NVIDIA/Troubleshooting

So I solved the problem. CachyOS was installed on a sata ssd and EndeavourOS on nvme-pci disk. I never thought he could behave any other way with graphics! I have an older Asus z270-p motherboard which has two m.2 slots. The tearing was the same in both and no settings in the bios helped. I bought the m.2 to pci 3.0x16 reducer (second slot for vga) and it works absolutely great and visibly faster
