DXVK is generally not responsible for rendering the mouse cursor (certainly not in this game) and it most certainly doesn't interact with mouse trails in any way whatsoever.
This is just one of those things that are going to be broken on Windows and I'd pretty much expect all Vulkan apps to be broken in the same way, at least w/o DXGI interop.
Hardware Cursor vs Software Cursor.
Pointer Trails enforces software cursor which can't be used in exclusive fullscreen. Why are you using exclusive fullscreen instead of DXGI interop?
@vlad54rus Because i dont know how to do that,
@xDoge26 Download Nvidia Profile Inspector then run it and set these two settings:
