I had the same problem. After disabling one mod at a time I found mod 342 "Indestructible Items - No More Weapon Degradation (Next-Gen Update Compatible)" was causing the error. Thankfully they already had an update available, going from version 4.00 to 4.03 fixed it for me.

Although Alex21xx's answer didn't directly apply to me (I don't have "Lucid Virtu") I had a similar enough situation that it led me to the answer. (Thanks Alex!) My laptop has 2 graphics processors and the system decides which one to use based off application profiles. "TESV.exe" was in NVIDIA's list of applications, but "TES_.exe" isn't. Anything that wasn't listed uses the default Intel graphics processor instead of NVIDIA's. For me, right clicking on "TES_.exe" and selecting "run with graphics processor->change default graphics processor..." let me see and edit the profiles. Once I set "TES_.exe" to match "TESV.exe" my framerate went from mid-teens to mid 30s.
