Fix #1- What I did was push the soft reset button on the Prime (using a small paperclip), then waited for the Prime to reboot. Once it rebooted, DO NOT let the Prime load up anything, just immediately go into settings, developer options, select the kill all activities option, then for background processes, select "at most 1 process only" Delete all of your running task managers/task widgets an that's it. Now all of my games run, no crashes, and the framerates for Nova 3 and Sonic is MUCH better.
Fix# 2 - For those still having issues with Mass Effect, this alternate setting will definitely fix the problem. After soft rebooting, go into development settings, and then for background processes, select "at most 1 process only" and DO NOT select kill all processes after leaving them. This setting has been confirmed to fix the Mass Effect issue, as well as all other games while still keeping the Prime running a lot smoother.
Please try using the exact instructions that I have posted, and let me know if this works for you guys. If so, then it proves that the os21 has a memory management issue which is causing all the current issues we are having.
Also, I would like to share this post from Jaycustom, whom has also been using this method for a few days now and enjoying it more than myself lol. He ran a CPU test to test the differences before and after my fix. See his results below:
Default settings said I had about 19 user/ 29 system processes running.
Dev settings gave me 14 user/ 11 system processes running.
Default settings for system memory 600+mb used/300+ free
Dev settings for system memory 300+ used/600+ free
The memory usage was pretty much exactly reversed! So I assume this is where most, but not all, of the performance boost comes from. CPU usage was also lower, not by much though.
See the video that I made (link below)showing me using the default browser, which is now really fast and stable using this method. I also ran Mass Effect 3 and Nova 3 to show that I have no issues playing these games anymore. I used a Samsung Galaxy tab to record, so please re-frame from laughing at the quality of the vid lol! If you guys would like me to try more games/apps, please let me know.
