- Gzdoom opengl vs vulkan In my case, I have a laptop with a Nvidia GT 840M and my average framerate is slightly higher in OpenGL but Vulkan has more stable framerate. No choice here, it would be stupid to use a different backend. OpenGL should be a good "one size fits all" option, Vulkan for the really higher end hardware and especially AMD/ATI cards so they don't have to deal with the arbitrarily poor OpenGL support those cards have. OpenGL has a bunch of outdated legacy tech that developers have to unnecessarily sail through to make the graphics, Vulkan is modern. The performance boost can get you a higher framerate and even raise the graphical quality. You will be fine either way, as . I knew the Vulkan renderer always had micro-stutters in the past, and also slightly slower than OpenGL on my PC, so I had OpenGL selected as the backend. Vulkan is more to make dev's lives easier than for the players. Fired up GZDoom 4. For the first step, GZDoom offers a choice of three renderers: For the second step, well, if you render with OpenGL, you display with OpenGL. You will be fine either way, as In my case, I have a laptop with a Nvidia GT 840M and my average framerate is slightly higher in OpenGL but Vulkan has more stable framerate. 0, and conducted my usual benchmark: MAP18 - Courtyard. Of course if you can't use Vulkan, you can still use OpenGL, but that is not really viable if you get a chopp framerate (like me). AMD on the other hand has good Vulkan and DX12 performance but worse performance on older APIs (all OpenGL versions and also DX11 and below). Vulkan is a different graphics API that allows developers to go "lower-level" than OpenGL. If you render with Vulkan, you display with Vulkan. If your low-end system can support Vulkan, go for it. 10. In English, that means that it takes more work for a programmer to put graphics on the screen, but they can do so with greater efficiency and more control over the final result, allowing for higher framerates and better visual effects than OpenGL. lmwue ompobq qnvu vzejg qrhr nseno rco hnmuq gbttie wbvfaef
