No change on the 11/15 Catalyst release. It's the exact same spots every time which makes me wonder if it's a texture caching problem. I have attempted to disable AMD specific driver 'tweaks' that are on by default such as "AMD Optimized" tesselation and "Enable Surface Format Optimization" under Catalyst A.I. with no change.
Would a video of the problem be helpful in any way since it runs into the drops at the same places?
