FAQ:

Q: My GPU does not support Ray Tracing, but my PC meets all the requirements (Windows 10 64, DX12). Should I install this branch?

A: If you have DX12, this branch also includes awesome high fidelity shaders that improve overall graphics quality and visuals.
You will notice better reflections, lightning, and detail, with 3 levels of graphics quality.
If your GPU is not on the list, you can still run this version but should not enable Ray Tracing in settings.
Enabling Ray Tracing with unsupported GPUs is liable to result in graphical errors and subpar performance.

Q: Is the DX11 version going to be abandoned?

A: No, this update also improves performance and unlocks Vsync. It was able to run 144fps on a midrange GPU (Nvidia Geforce 1660 / 144hz display Vsync/ 1920x1080 ).
