    A speedup of 10%, or less, is more likely (if such an OpenGL/Vulkan driver existed). An iGPU is accessing DDR4 memory (20-40 GB/s) while GPU is accessing GDDR5/6 (200-400 GB/s).

      I am a bit confused by this: I have been using DRI_PRIME to force the use of the integrated graphics over the discrete AMD one... would I experience much of a difference by using MESA_VK_DEVICE_SELECT=

      Is there any kind of flexibility to take advantage of? that wold be really cool.
