Hello. I'm reaching out for help with a frustrating issue. I've searched the entire internet for answers and assistance, but nothing has worked. Here's the problem I'm facing and I hope anyone had the same problem and somehow managed to solve it

: during every dialogue, textures reload. Let's say I start a conversation with one of my companions. At the beginning of the conversation, the textures are fine, sharp and hi res (I have textures set to ultra, I'm playing on an RTX 4070 S card, I'm reading the readings from Riva statistics server, and I'm not running out of VRAM). However, after a few seconds, the textures of faces, armor textures, and even textures appearing behind the character (like rocks, stones, a brick wall) simply reload themselves, just like that. The quality drops from high resolution to low resolution, and from that point they improve every few seconds to reach the highest resolution again. And that wouldn't be a problem because eventually the textures would load. But no! Unfortunately, after a few seconds, the whole process is repeated. I don't need to do anything. I just stare at the close up of my companion and textures just change constantly in cycles. Every time they change, I notice a small spike in my frame rate graph.
It's strange but I didn't notice it earlier - I'm still in act I. There are only goblin camp and underdark for me to explore and I noticed the problem when I entered the goblin camp. I'm very picky, so I can assume that I would notice it earlier but I'm not 100% sure. Now I only want to repair it somehow

That's so annoying. I tried to change every setting in the graphic options, I changed D11 to Vulkan and vice versa, I changed the locations of game files (from one SSD to another), all my drivers are up-to-date, I reinstalled the game - didn't help, I tried that HDD mode. I'm playing with over 100 mods but none of them change original textures. Ok, I know that this is where I should start checking but it would be impossible in few cases because I've got few mods that when You start playing with, You need to continue with them, or the game gets broken.
I just want to know if there is any1 that have a similar issue and somehow managed to deal with it and would be a good man and share the solution

Thanks in advance.
