Your system information

• Nvidia 1660ti (6GB VRAM) + Ryzen 7 3700x Running x11
• Have you checked for system updates?: Yes

These usually last 10 seconds then it works normally, but that 10 seconds the game is completely unplayable. It doesn't behave like vulkan shaders induced stuttering.

When it happens its the CPU that is doing something. GPU usage falls down a lot. It also seems to affect movement, it slows you down.
