This appears to be an overheating issue, but I don't understand why.

Playing Diablo 3 -and I've only seen it happen with that game- after a relatively short time (~15 mins) my rMBP will suddenly log me out.

Shutting down due to thermal limits being reached would make more sense, but this just logs me out.

I've ramped the resolution down to minimum and capped frame rate at 60 fps but it makes no difference: ~15 mins into playing I get logged out.

I'm especially surprised as I don't have these problems on a similarly specced (i7 Haswell) MS Surface Pro 3: sure it gets warm but it keeps going. And the SP3 only has integrated graphics whereas my rMBP has a dedicated gpu.

Any idea why this happens?

Is it perhaps due to difference in Windows versus OS X graphics drivers?

Your post is not really clear - Do you actually get logged out (and you see your OS X login screen) - or does the game simply quit (dropping you out of a game server)?

Maybe it's the game kicking you off, embarrassed because of your poor game play :D

You can certainly find out easily if you are having any kind of overheating issues, by using a utility that will display the temps reported by your hardware sensors.

You can also find out the reason (or at least a reason code) for OS X logouts in your console, then the system.log
Events will be listed in the log by time and date, so you can quickly look at what is recorded at about the time that you were logged out.

If you have the NVIDIA GPU, have you tried updating your drivers through GeForce Experience? NVIDIA are great for drivers (AMD, not so much). Could be that the game is crashing.

As the poster above said, please could you provide a little more information? If it overheats then the laptop will just cut out rather than closing the game.

Not sure why a windows program would help me.

Nope just logs me out -close all open programs, takes me back to the login screen.

I've had my Mac Pro shutdown due to overheating it's graphics card but that was different; literally just shut down with no warning, but this isn't what's happening.

Weird huh?

OS X Login screen.

Hey!

You can also find out the reason (or at least a reason code) for OS X logouts in your console, then the system.log
Events will be listed in the log by time and date, so you can quickly look at what is recorded at about the time that you were logged out.

I checked there. Got a bunch whines about permissions on a file (ran disk utility and repaired everything) but didn't help. Nothing obvious like "Kernel panic: forced log out blah blah blah".
