I am looking into this with a set of 3 total experiments.
The first experiment is: comparison relative uz compression between both packages.
My theory is that they would end up the about same, which would pretty much kill the purpose of having that work of compressing (due to redirect services on servers, and a more effective zip when distributing it).
However, having made the experiment:
Original textures: 2.3Mb >> 1.2Mb
Optimized textures: 1.2Mb >> 800kb
So as far as the first experiment goes, it worths the trouble of compressing.
Now, the second experiment I will only be able to perform when I get home (10 hours from now D: ), and will consist with actual usage and tolerance to potential crashes and compatibility issues on a pure v436 install.
So, I invite everyone in first instance to test this mod in different machines, in different renderers, resolutions and texture quality settings.
If it gets corrupted in a single one of these, or if it crashes a single renderer, well, then... ):
The 3rd one would be trying these in a server, with redirect (but I guess that test was already made).
But if everything works and passes in your tests and the tests I am going to perform, then Dr. Flay made the discovery of the century
