Can the DLC be bought with the GMG copy, that is, with a game that isn't on Steam? :) Disgusting practice by the way.

I am using the Combined Operations from GMG. He does NOT own the DLC for a fact. What I see: What he sees:

So without the DLC, all skins are THAT blurry? My friend doesn't own the DLC and he sees my skin in high resolution :l

Hello! Since 1 or 2 days, the textures on my character have become really low resolution, as if the game was on 'low'. But it isn't and my friend sees the textures as they should be. We play on the same server but this issue is persistent on all servers. Is there a fix? AMD 7970 Intel i5 2500k 8GB RAM
