Perfomance issues

I'm having a problem with the game. I've searched all over the internet and haven't found anyone else with the same issue.

The problem is mainly with Vulkan, where the game runs smoothly for 5 minutes, and then suddenly the game's texture completely breaks. I'll leave the videos and photos here in this post.

With DirectX 12, another problem occurs. Sometimes my GPU just gets tired of rendering the map, and the FPS drops (and so does GPU usage, around 50%). And when it does work, it only works until I have to switch maps. As soon as I switch, the FPS doesn't go above 10. Another thing that also happens is that my CPU's MS remains at 300 when the map change happens.

With DirectX 11 it becomes quite unplayable, because the FPS hardly goes above 30.


I checked the temperatures; nothing goes above 70 degrees.
I reinstalled the game and Windows.
I tried an older video card driver.
I tried to update Vulkan.
I tried using the optiscaller.

Nothing helped

This is the only game where this happens, if you're going to accuse the GPU of imminent death.

SETUP: GTX 1060 3GB, AMD 5500, 16GB RAM
