I've encountered the same issue. Clean install of W10 on HP Envy 17 2080en (Intel HD 3000 + AMD Radeon HD 6850M), tried playing Rust, got stuck with 10-13 FPS. I checked in CCC and the game and Steam were both set on 'Maximize Performance', and yet. Thought it had to do something with my BIOS version (F1C) because there's no option to enable dynamic switchable graphics, but then I read that it's not important since new AMD graphics drivers change that and there's no need to use modded BIOS. I've tried every single combination of graphics drivers and nothing changed.
