What is the option 'detailed textures', what does it do and is it worth to even try to fix it? When I turn it off, everything works fine and looks fine I guess. Textures are already set to max detail anyway. I'm using an old laptop with Win 7.
Also, additional questions.
1. Is there any kind of STABLE HD texture pack / widescreen patch I should install for the single player?
2. Is there a no-cd patch? I just bought the original physical copy, but I'd like not to be forced to keep the disc always in my laptop.
