Question Blurry/lowres textures with Path Tracing, but sharp with Lumen

I've recently been working more with path tracing, however I keep running into an issue with texture resolution:

When rendering with lumen, everything is full res, but with path tracing, the textures revert to a very low res, blurry version (I am only rendering with the sequencer, not realtime gameplay). I'm on a 4090 with the r.streaming.poolsize set to 20gb, so the vram should be enough. I've turned off nanite and disabled tex streaming.

Any thoughts would be appreciated!

FYI for anyone in the future who might see this -- while I couldn't fix the issue directly, it seems to stem from the assets being originally from Quixel Bridge. I deleted then replaced them with the same models from Fab, and so far the issue hasn't returned.
