The crashes in 32 bits disappeared in the last two updates of UDK. I guess it was a problem of UDK.
Chosker, I'm ussing bUseCompartment, but I haven't any problem with this in any machine. I have tested with a 240 GT, a 9800, 750 GT and 660 Ti. All from Nvidia, the problem is with AMD or Intel cards?
well I was doing a private round of testing of my game and only one guy (Neongho, actually) reported these strange crashes.
a few months later my nvidia GTX 560Ti died and I bought a new nvidia GTX 970 (and no other piece of hardware or software changed), and in there I got the same crashes so I'm 100% sure it's graphics-card related
