Yeah, I was excited to play it since it's the only Halo I haven't, but it's too laggy for me to be able to enjoy. It is playable. But not at an enjoyable framerate. I heard Gears Of War on BC sucked too, but was fixed. Hopefully it's the same with Reach.
M$ said they would fix it. Really it's an absolute fucking shame that one of my favorite games of all time has been reduced to a literal eyesore that I dont even want to touch at this point.
lolreach is major utter shit
