------- Additional Comments From l_bratch@yahoo.co.uk 2007-14-05 17:16 ------- I found something out by accident that could be potentially useful.
The game crashes as per this bug in every resolution except one - 1280x1024 fullscreen mode.
Normally I play/test the game in windowed mode at 1600x1200, however when I switched to 1280x1024 fullscreen mode it was fine (I tested long range headshots on de_dust several times with no crashing).
1600x1200 fullscreen still crashes and so does 1280x1024 windowed.
If it helps, my normal desktop resolution is 2880x1200 with Nvidia's xinerama extension.
