Yep; the patch is out and it fixed the non-saving issue of the user setting, it also allowed for the screen brightness setting to carry over to MP. Awesome!
And while it made MP more enjoyable for those of use who have CRT HDTV's (the game is not too dark anymore), the MP still blows imo. The SP is top notch, though. SP is just more polished then the MP, and more fun. I do love the better melee (animation and functionality), and rag-doll physics when you melee or gernade the enemy in CoD3.
Also comparing it to CoD2's graphics, it is very apparent that the game is running in a 3rd less of the resolution then CoD2's true 720p. The textures are very good and all in CoD3, but the resolution is noticeably less textures. Everything is just comparatively more 'dull'.
