Extreme and Horrifying Issues with running Darktide/Performancee

I had horrible performance issues on my 5070ti system, texture pop in, textures not loading at all, lag spikes when a horde spawns. I probably read every single thread about performance at least a few times and in the end they were all at best leading in the right direction, but none could really fix my issues. The only thing that did anything noticeable was this thread:

So I linked the post and both config files to deepseek and asked for an explanation to what each value does and what I should change and why. Changed some values, tried it, gave feedback, changed some again. End result is, issue is literally gone. I don’t have mesh streamer disabled and I am using all high settings (including textures), 1440p ultrawide, dlss performance. I get like 120+ fps without fg during horde events or whatever. 1% lows are like 90.
