Powerblazing

Its amazing no one has ever solved this. Im new to gta mods, lspdfr and all that. I have a good rig, over medium specs (6700k, 2060rtx, 16gb ram) and i play gta v vanilla without any issues. Im tired of listening to people say "just put the main.preload all models to false"....i already did that, everyone here have done that. I also lower all 4k textures to 2k, it was better but the issue was still there, just takes longer to appear. Now my question is: if i dont even have a 2k monitor, wouldnt it be better instead of lowering 4k to 2k, lowering all the texturex to like 1980*1060 or something like that? i dont really know how textures work, but i can only watch videos in 1080p, so why would i have 2k textures if im not gonna see them? Issues with texture are killing my joy and will to play this beautiful and amazing mod.
