I couldn't see it being 100 lines, but i suppose its a point that perhaps there should be a built-in method of determining (sp?) what you want, although saying that, doubt it would be a 'flag' for such a thing, and similiarily i wouldnt have thought it would be a new identifier just for that purpose, suppose its upto Khaled as you said.
Also, 3D games + any other program = yuck - although i suppose it depends on your system, though saying that this is a 1.6Ghz, 512mb machine and i still even kill Explorer before playing games.
