Compresses the 6K textures of the Humvee in White House and probably make the game playable.
So, long story short. The humvees you see in the White House heist were directly ported from that one The Walking Dead game. As with every Unreal 4 asset, it has ultra poly model (23k polys) and several 2k-1k textures making up each individual component of the humvee. Which is one of the reasons why White House runs so poorly besides the map itself being an incomplete unoptimized rushed mess.
This mod cuts down the size of the large textures (2-5K kb) by half, bringing them down to 500-1K kb without totally compromising the looks. Smaller texture means less memory usage and a relief for your burning hard drive. Despite this, I still recommend setting your textures to Medium before playing the heist.
Update: Added optimized model edition.
This version also includes an optimized model of the humvee, reducing poly count from 23k to 16k while also adding Level of Distance (LOD) models which further reduces poly count when far away from the humvee.
