Game stuck in potato mode

After updating to the newest expansion, most textures appear to be forced into the lowest possible quality. It looks similar to when one edits the files to force the game quality far lower than is possible, but my settings have not been altered. Changing texture quality and dynamic resolution settings did not improve the appearance.

I'm having the exact same issue. Akin to OP, I toyed with the settings to no avail. I also double checked that my NVIDIA display drivers are up to date.

Also using directX.

I'm having the same problem, my graphics are completely whacked. Not much useful info here i know, but i'm not sure how else to explain it. It's like the graphics never finished loading, but the game is playable.

Exact same issue for me too
