The game performance is very slow. There is a topik on GitHub where you can read all NVIDIA users have low peroformance ~15-25 FPS no matter the video settings.
In the mean time the game runs perfectly well on AMD and users are reporting 100+ FPS.
I’m with 1080 Ti and I experience the same problem with low FPS. I tried the latest vulkan drivers 440.66.03 and the stable one 440.64. Tried Flipping on/off, different OpenGL performance settings, different powermizer settings, compositor on/off, different resolutions, spoofing AMD card, enable/disable nvapi to no avail.
