I prefer to have a free of pixels version.
Therefore I have batch-processed all textures with xBRZ 6x and run them through PngOptimizer (saving 200 mb uncompressed).

This now includes all later patches:
- Removed some artifacts of a Doom texture and Doom 2 menu.
Recalculated and reset the offsets.
Fixed issue with Plutonia texture and Arch-vile
