Black Screen after intro

[Urkle]

have you tried newer nvidia drivers??? I have a 6200 card on an amd 2100+ w/ an SBlive and pulse audio IS configured (no clue if the game is going through that or direct) and do not encounter those issues. (using the packaged libCg). The difference is I'm running Fedora 10/11 and the latest nvidia drivers (180 and now 185). Try upgrading to the 185 series drivers and see if that fixes issues.

Also look at your /proc/interrupts file and see if the two devices (sound and video) are sharing an interrupt.
