I have found out, that playing on disc can cause overheating, I played war thunder(discless game) for 8 hours straight not a problem, the next day after an hour of DMC5 it overheats. What’s happening is when u start playing on a disc game the disc spins around and all that $@$* and it just takes more power to run disc rather than discless games. That’s for me anyway. But I did see a guy on here say he was playing warzone good then the last of us is what did it, I bet he was playing the last of us on disc, or maybe this is just a solution that works for me I dunno. Oh and my PS4 has been used a lot I got it day 1 the release day and the PS4 still worlds amazing downloads take 10-20 minutes longer maybe even an hour because of the dust and stuff but an xtra 10 minutes ain’t too bad. And my internet is really good so that’s why I don’t care only took me like maybe 16 hours to download war zone which back on my old wifi would have easily taken 2 weeks but now I’m free of that sh*t. Yes 16 hours is still quite a bit of time but the game is like 100GB’s. Anyway in conclusion PLAY DISCLESS ITS BETTER and u don’t have to change disc each time u wanna switch game.
