Take my advice, Play a 1v1 with a hard opponent or expert.. If your Rig is on the lower end, don't even try 2v2. I never do.. The other AI's just get in the way.. The skins, however, are beautiful even on low settings, IMO I dont even notice , unless you zoom right on in.. I would say my rig is on the lower end, even with my 512 Geforce 98GT, I crash often toying with different settings, but now ive found "THE SWEET SPOT", and the mod is smooth and fun. Its everyone's tendency to "push it" a little, thinking the mod will look bad if you don't have the settings higher..
For the sake of an argument, there really is no possible way to make a " different version" of the mod, It would take away so much from the vision and concept to do this.. I would suggest playing our "Brother" mod- Blitzkrieg, it has great units, features and skins, all at signifigantly lower memory demands, for those with lower end rigs.. It even can play the campaigns as well..
The object would be a compromise, but not at the expense of chopping the mod to pieces so EVERYONE can play, because again youi cant please everyone all the time.. Not everyone can play Crysis either.
