    chimpy I'm not sure. That depends on my personal situation in the future and the state of the code of the AMD vulkan driver when it is open sourced.

    jrch2k8 We have a new NIR->LLVM pass that does a direct translation.

        another big fail by amd non free driver, put your ppl working with opensource driver and fogert the catalyst/amdpro for once

          not really. radv won on cpu-bound tests because it does less work on cpu. on gpu-bound tests radv lost because less work on cpu means less optimal gpu setup

            it's not just legal review. somebody has to turn windows vuklan driver to opensourceable form. they have no resources for that, so do not expect they will magically find resources to maintain another driver

              btw, it was neither full nor from scratch

                  BNieuwenhuizen Well hopefully AMD and their people (Bridgman) will reach out to you and David and lend their resources. If Radv is this far along, AMD should might as well use it.

                    irrelevant, intel does not use llvm

                    lol, that compiler will generate code for intel gpus

                      RADV is a very interesting project, maybe even better than the Intel Vulkan implementation already. I hope there will be much more Vulkan games in the near future. Btw. an article about the state of HEVC Main 10 decode would be interesting as vdpauinfo/vainfo show support for it with Polaris GPUs. A working implementation would be very cool. Kaby Lake based laptops/NUCs should be available soon too, so this could be compared then. Kaby Lake desktop CPUs take a bit more time.
