I started playing halo 1 story mode 1st with the first cutscene opening I tried pressing that back button to change it to classic look it didn’t work so I skipped the cut sense then when the game loaded to play I was able to change it no problem but I wanted to see if it would switch bad no problem if I restarted the level and it still didn’t work with the back button at all for the cutscenes so I wanted to see if it was the same thing as Halo 2 Halo 2 had no problem switching back and forth with the cutscenes when starting a new game.
You cant change the look of the game during cutscenes in Halo: CE. I dont know why, but you have to either select prefered graphics when selecting a mission or when already loaded in.
