Amnesia The Dark Descent Demo problem

[Vince]

On linux I gave: "Segmentation Fault" (I'm using newest open Radeon drivers)
On windows this same problem like others...

I think it's a problem with Frame Buffer, and Resolution. Why? On linux "Segmentation Fault" mean "undefinied memory at this address", or "out of table" (i don't know how to explain it in english, trying to get value that pointer points to, but memory at this address were not reserved).

Those segfaults sound mostly like using GL extensions that are not supported by the card/driver (thus returning NULL) - because you have to fetch their address first.

I noticed that the textures for example startup_fg_logo.jpg haven't 2-power sizes. This file has 1024x768. When I resized it to 1024x1024 there were no tilling. I will check on linux, if that resolve "Segmentation Fault" problem. If it will, this can be the reason of crash. Older cards (or drivers) can have problem with unsquared textures. I had similar problem with my game.

ATI cards have SERIOUS problems with non-power-of-two textures, I had problems with that myself at my university (half of the PCs in the pool had ATI cards, half had NVidia, we were programming GL). It can bring the machine down to a crawl. Maybe that's the problem under win?
