Campain BUGS

HI !Here is a list of bug still present in the campaign of the game.
Bug No1 halo CE impossible to start with classic version
In the start screen of halo CE and halo 2, there is an option to start the game with the classic graphics and music and each time, after having accepted the changes , the game always starts with the remastered version, when I save and quit, its back to the default settings (remastered for both).

Bug No2 halo ce remastered Not 60fps
The Halo Ce remastered graphics seems to be in a constant stutter, the cutscenes and the game itself, when you switch back to classic, everething went back to normal,its as if the FPS fell to 50 constantly, the best exemple of this is in the truth and reconciliation the cutscenes stutters and the gameplay seems not to be in 60 FPS.

Bug No3 halo 2 anniversary laggy cutscenes
Some of the brand new CGI cutscene of halo 2 anniversary are not stable, there is some minor and major sudden cutoff, the worst of all is the end of the cairo station cutscene , when the ship passes behind the glass,it stutters like hell and always to the same places no matters how many times I reaload the mission.

I know that your focus is set on the multiplayer but those bugs are present from the beginning and I hoped a correction to finally enjoy the first two episodes. thank you !
