I do not know what you did, but returning to test the game, I entered the catacombs right on the beech beside where you land after the ship. I intentionally set of the bombs as they are a good way to test how the game manages to handle memory utilization and CPU loads as they are procedurally generated every few rounds, then they explode etc etc. On patch 8, i was getting around 90 FPS, on return to patch 9, the same place HARD LOCKED MY PC after 20 seconds, and i was at 3-15 fps [according to Radeon Software]. This is completely unacceptable. Before patch 10 comes out, you folks need to go back and fix these issues. Every single patch its gotten worse. Patch 7 i was at 140 fps doing the same identical test with identical settings.

At the point of crash my PC was only using 40% of my CPU.
Hopefully this feedback is useful.
