I'm having similar issues and it's been driving me crazy since last night. I did submit a bug report. I tried every single recommendation on this page (yes, every single thing...) and nothing worked:
https://larian.com/support/faqs/graphical-issues_83Was working fine up until around 1am EST on Sep 7. Tried playing again around 9pm EST Sep 7 and suddenly half the graphics just would not load at all (just black areas/voids) or textures wouldn't complete. See image links. I waited ten minutes and they never loaded. I didn't wait longer than that.

I typically play at lower settings, but have had no issues at all prior to this (it's been playing great at medium settings). I feel this must be related to Patch #2.
Right now I'm reinstalling the game and if that doesn't work, I'll try rolling back the patch.
