    Why doesn't AMD support for OpenGL??

      Why doesn't AMD support for OpenGL, it's so important for so many things, most importantly videogames and emulation which is probably the reason you would buy an GPU..

          AMD supports OpenGL & Vulcan.

           

          This from an old article in 12/2017 that indicates that OpenGL and  Vulcan are supported in the AMD Drivers: AMD Adrenalin 17.12.1 Released (OpenGL 4.5/4.6 + Vulkan 1.0.65) – Geeks3D

              The OpenGL Drivers are so primitive though they're so bad, When running an OpenGL based emulator I get better preformance using a weak Intel GPU rather than my powerful AMD GPU.

              I also heard that they're capable of fixing them but they just don't want to, why?? we need them!

                  AMD's OpenGL drivers aren't bad exactly it's just that Nvidia's spend more money on it and of course Nvidia fully support all their own OpenGL extentions which a lot of OpenGL games and apps use. AMD have equivalents for many but they're not always supported well by apps.

                   

                  Then of course you have the problem that AMD's GPU market share means that many small software companies and indie devs don't even bother to test their software on AMD hardware (same goes for Intel's CPU dominance meaning their IGP's get reasonable support, although that's changing) Plus Nvidia do stick their oar in A LOT with smaller devs going so far as to send teams to them to help "optimize" their software for Nvidia GPUs, AMD just don't have the budget for this.

                   

                  Where emulators are concerned, most are open source projects run by one or two people, as such they use OpenGL because DirectX isn't free and again they often just don't bother testing with AMD hardware since they simply don't own any. Thankfully most of the better emulators are moving to Vulkan for the same reasons they used to use OpenGL and AMD's GPUs are much better at Vulkan (in part because of Async compute which Nvidia's current GPUs have no real hardware support for and in part because AMD's mainstream GPUs have much more raw compute shader power for example the 1060 has 4.375 Tflops but the 580 has 6.175)

                    Since you mentioned that you are running a OpenGL emulator maybe try posting here at AMD OpenGL/Vulcan Forum. Someone may be able to help you get better performance from your OpenGl emulator: OpenGL & Vulkan

                  AMD DOES support OpenGL. Actually, this is what I'm working on.

                  We would try our best to help.

                  Please post your specific problem in OpenGL & Vulkan .

                      How do i post there? i couldn't..
                      Anyway the problem is present in all OpenGL based emulators, Most notebly Citra emulator for the 3DS, where when you run it using an Intel GPU it runs fairly good depending on the GPU but when you ran an AMD GPU even though Way more powerful than the iGPU, the emulator lags horribly and gives nearly 2-5 fps and 15-20% run speed.. knowing that the 3DS games are not graphicly demanding at all..

                       

                      If you could check out why and fix it that would be great, because it's really saying something about your GPUs and Drivers at the community..

                       

                      the issue is a bit better when it comes to the other recent Wii U  Emulator "CemU" but it's quite the same problem as well the graphics are very weak compared to Nvidia GPUs..

                       

                      Best of luck.
