My "bandaid" fix for crashing, which never happened until I installed a few high res texture mods(faces, water, smoke, sky), was the LAA launcher. It seems to have 'fixed' the CTDs, but I still wouldnt call it a solution to the problem.

Try this mod out instead of using texture replacers, it helps to make textures look sharper and higher res

. I disable the Bloom effect myself though.
