Quick Resume making Modern Warfare crash, have to quit game fully every time to start it...

Games that support quick resume automatically add when you start them. There’s no way to disable quick resume

I just delete it after I manually quit the game every time.

if you're using quick resume, this often breaks achievements, I suggest you make sure that you press the start button to go down to quit every time you finish playing the game

I'm afraid you'll have to resume from an earlier save or start over if they don't pop on their own. I've had achievements pop years later

Quick resume is not something that can be disabled at this time. You need to go out to the dashboard, hit the start button on the game, and go to quit to ensure it does not enter quick resume

Quick resume works by either keeping the ram energized while the rest of the system is off, or by dumping the ramp to the hard drive and then retrieving it later. Many games, especially older ones, have issues with restoring network connections if you quick resume. I personally do not recommend using the feature and making sure you with every game when you're finished playing by pressing the start button on it's icon on the homepage and choosing quit

Quick resume is temperamental with many games. Make sure to exit to the title screen, press start and choose quit before shutting down
