can anyone help me with changing the mat_picmip from 2 to 4 on the very low preset?

so i was trying to change the picmip scale in mastercomfig (not in the custom.cfg, but in the actual vpk that you download) it said that the mat_picmip was 2, but i wanted 4. i changed it to 4, but tf2 didn't load, please tell me how to fix it, my pc is trash, and i just want better fps. :) <3
