Couple things I notice on this...... whatever program you used to "upscale" the texture seems to have removed some detail in a few places. Just increasing in size in PS or using waifu 2x will do that. It also doesnt look like you upscaled the alpha layer of the normal map separately (as alpha wont get touched at all in upscale software). You also failed to upscale the multi as well.
Yeah it's a pure algorithmic upscale, I'm considering using it to upscale all armor textures, but I'm trying to find out what the multi texture does before working on it. If you have any information about it I would be thankful.
There are many functions that the multi does. I cant remember it all this link has a reference sheet of what is what https://goo.gl/XGxx2s. And I also see in your screenshots you use my scales lol. Just know that you CANT upgrade all gears. Gear as a whole has a 50/50 chance of working. Ive spent better part of 2 years perfecting HD assets. If it works neat but when it doesnt it looks horrible.
