Same issue here...I've got more then enough power and only getting about 30-40 FPS. Should be well over that. Specs: i7 9700RTX 2070 8GB16GB RAMGame is installed on an SSD...
Should've named this update "Bound by Bugs" I refuse to play the game and let it ruin my experience till these are fixed. The patch did nothing for me, still continues to crash. I'll be back in a few days!
