I have found a very good d3d8 to vulkan patch that works well with Sub Command and Dangerous Waters on windows 8,10,11
This d3d8 patch allows proper detection of most modern graphics cards and enables all 3D Features.
I have used this patch myself with the NVIDIA series cards, haven’t had a chance to test on AMD graphics cards yet but should work well with any card that supports the Vulkan API.
This greatly improves the framerate to the order of 290 to 509 fps on a laptop with windows 10 and a Nvidia Geforce GTX card, even better on the RTX series.
