That was me two days ago using the dx11 beta. I couldn't even craft that day, they were so instantaneous.
Even after the patch yesterday, I am still experiencing crashes with dx11. I took off the beta, restarted the game and no more crashes. It's a shame, because I did see a lot of performance improvements with dx11 enabled that first day - almost no freezing and I was able to actually avoid Teq's attacks due to no lagging. I'm not sure how any of the other metas performed because they crashed. I was even able to tab over to my PC settings without the game having a seizure.
Due to all the crashing, the dx11 is basically unplayable for me in its current state.
