So WB Support got back to me re: my latest video and ticket update. They want me to try creating a new Profile in Windows, download the game again, and test.
@Immortal , you really seem to know your stuff, so can I ask your opinion? For me, the game played flawlessly until Patch 5, that Patch seems to have been what introduced the frame rate issues I'm now experiencing. The Performance Hotfix improved my overall performance post-Patch 5, lending credit to this theory, though it's not back to post-Patch performance.
On Jun. 8th, I formatted my system and clean installed everything. I'm running the latest version of Windows 10 Home, the latest nVidia Drivers, etc. The problems persisted after my format; there was no difference.
My question for you is, in your opinion, do you agree that creating a new profile in Windows 10 and installing and running the game from there will likely
not produce a difference? Seeing as how a full format did not, that's my own thinking.
