Apart from this… not a lot. AMD and Intel customers will need to instantly set Vulkan as their backend and by no means look again whereas Nvidia customers have the luxurious of alternative. Whereas usually Vulkan will seemingly be the higher choose due to its decrease shader stutter, there could also be some video games that render/carry out higher in a single or the opposite, so the world really is your oyster. Shaders constructed for one backend will rebuild into the complimentary set for the opposite once you swap, so nothing is misplaced by attempting each. A very good technique could also be to endure the preliminary stutter with Vulkan after which swap to OpenGL if it performs a little higher. Your alternative.
