Since the patch, my game has been crashing to desktop approx every 60 minutes. No discernible pattern to it, sound stops and about 2 seconds later, back to desktop. No error messages, no warning noises, nothing.
I don't think so. I haven't experienced this issue with any other cpu intensive game. The issue seems to have abated for now though.
Heavy use of the PD may cause this - there's a not insignificant memory leak of around 16MB on each visit. Couple that with multiple dungeon levels still loaded, and your computer might just be killing the process to free up RAM. ...This may also have nothing to do with it whatsoever, too.
