Good evening @Bo Jensen, This can happen when the graphics card drivers are not up to date, or when you have a non-Vulkan compatible graphics card (this remains rare these days). try starting the game in a lower resolution, playing with graphics settings, try a clean reinstall of RWE 2, carefully following the installation procedure. However, we must keep in mind that, despite the excellent quality of the software, it remains an overlay on top of the existing game, and that, on certain machines, with more modest configurations, we can see an impact on the Overall FPS. .
