Crash to desktop after leaving first area.

[jens]

It is probably a setting that is used by some texture, which is not present in the first level, but in the second level and possibly later levels. So when running high and having this setting active, the integrated chip can't handle it and crashes. Running medium settings probably have this particular setting disabled. If you want to experiment, you can run on high, but turn of things like reflection, refraction and what not and then turn things on to see which one it is that makes it crash.
