------- Additional Comments From ekohlwey@gmail.com 2007-23-02 22:48 ------- after doing some research on Google I've found this may be a problem with the source engine itself. Unfortunately I'm not familiar enough with D3d or wine to provide more feedback.
No system changes (this is on a laptop), and the problem doesn't affect hl2, just hl2:episode one.
