I am trying to benchmark an Intel HD Graphics 520 (integrated) and a AMD Radeon R5 M330 (dedicated), but I am not able to specify for Unigine Superposition which GPU to use. Here is the result window from a benchmark I ran: As you can notice both GPUs are listed, but since the listed driver is i915, I can say the GPU that was benchmarked is the Intel, and another clue is that in the main window for changing the benchmark settings (resolution, shader quality, textures quality, etc...) It says there are 3GBs of VRAM, and in this result window it says that the Intel GPU has 3GBs, so I am sure it is benchmarking the Intel GPU.
Now the question is:
How can I benchmark the AMD GPU? I tried using
DRI_PRIME=1 which always works with other software of all kinds, but it didn't work with this benchmark. When I use
DRI_PRIME=1 I got almost the same result (753 to be exact), and the same details under Configuration. Also 3GBs of Graphics RAM in the main window, which confirms it is still using the Intel GPU.
