This mod is for those who want to play with high grass settings and gain a few extra FPS. In a nutshell, it decreases textures resolution of procedurally generated grass in order to improve performance with grass quality set on high/very high/ultra. If this isnt low res enough, I will make another version with even lower resolution if it helps.

Installation:
For grass, replace the .ytd files in following directory: "x64i.rpf\levels\gta5\props\procedural\v_proc1.rpf"
For trees, replace the .ytd files in following directory:
"x64i.rpf\levels\gta5\props\vegetation\v_trees.rpf"

UPDATE: Now includes lower resolution trees (almost no visual difference) and lower resolution grass.
