Penumbre Lag when turning WTF

[arvidnelson]

Same problem here -- game was working fine, up until level 6. I turned all the graphics to the lowest setting and restarted the game, but it did not make a difference.

Any help you could offer would be very much appreciated!

Running a 3.06 GHz Core 2 Duo iMac with an NVIDIA GeForce 8800 GS. OS 10.5.8.

Thanks!
