Not totally QC related, but I've seen this happen in QC plenty (well, caused it ;) Brief summary:
I make a GLSL shader which is particularly slow and complex. Say a mandelbox raymarcher. It works perfectly - over 1 fps! on a geforce 330m at 640x480. Next, I crank up the resolution to 4kx4k. It's within the spec of the GPU, and should run. Very slowly, but it should run. A quick calculation suggests it should run at ~100 seconds per frame. The window appears as expected, I wait.. and after 30 seconds I get a kernel panic. On my home mac (imac with radeon 2600) in a similar situation the computer freezes, with the mouse still working but the screen never updates. Only way out is a hard reboot. So, is there some kind of limit on the duration of a shader execution, after which the system just rolls over and dies? Any way around this? (On windows, it seems to work OK - the system totally locks up until the shader finishes, but at least it's possible to run it). Chris
