Hmm...I play halo every day but single player I havent played in months. I'll have to replay few halo's single player levels...and specifically look for frame rate issues. I assume when you fight 2 of those giant spider things is when they will most likely happen.
I don't know why but I've never had issues with frame rate in 360 games...my TV does have the 120 HZ auto smothing thinggy...so that may help.
Like some games have noticable dips...Ninja Gaiden 2, Too human...even Sonic Unleashed. But I dont mind it...
