Greatly reduced FPS after the SotV update

I’ve been having FPS issues ever since I’ve bought the new DLC. I have FPS issues even at the 1st level. I run on a modded version of the game most of the time but even vanilla works very poorly. I thought it may have been nvidia control panel running the game on my integrated card but that doesn’t seem to be the case since I’ve seen a marginal FPS improvement after switching the preference to an actual v-card. Here are my specs in case that may help:
i7-7700HQ
16GB RAM
GTX 1060 6GB
Game is on a newly purchased SSD.
