Here’s some issues I found with your log that might help.
CPU JIT should be enabled for the best performance. Please enable this option.
Lots of awesome advice here. Yeah, by looking at the whole driver finding page on AMD’s site (where you put in your GPU series and select your model and all of that), they should show you the latest version of the driver. I know your CPU is fine and should be a fairly good experience, so like others said, it’s probably just a driver issue.
So… Download the latest compatible driver. It seems to be 15.7.1 (WHQL) so should be stable.
