looks like v7 isn’t for me at its current state. was curious if my AMD GPUs are finally better supported by cycles but the performance is still bad, so no improvement here jet. it really is a shame that AMD GPUs don’t perform nearly as good as they should.

WIP has still same Cycles codebase as v6. I am working on a rebase on latest Cycles though, so hopefully this or next month you should see improvements over v6.
