I’ve noticed an increased number of people that find my blog by searching for the term ‘Splinter Cell Double Agent crashes’ and then end up at this post.
There are a few things you can do in that case if you’re on the 360 version:
1. If you have a crash and reboot the 360, leave it turned off for a few mins.
2. Clear the cache when booting the title. Do that by pressing and holding the A button down from the moment it loads until you reach the press START screen.
3. Don’t open your Guide or Friends List during a cutscene/loading screen or when a lot is happening on screen.
Hope that helps. Personally I found clearing my cache every time I booted it up did a huge difference in the amount of crashes.
