So, I decided finally to try Avernum 4 demo, and there's seems to be crashing problem. I start the game, play for few minutes, game crashes, computer goes to total lockdown, and maybe even to BSOD. It seemingly happens after few minutes of playing, and always during combat. I tried everything, switching off sounds, updating drivers, etc... But it stills crashes. I changed recently my graphics card and power, but all other games work perfectly. And the computer is:
Amd Athlon 64 3200+
Abit AV8
Radeon X1950 Pro
1,50GB DDR
Edit: And oh right, OS is Windows XP Pro.
