I got a crash too as it tried to load the cut scene for the second level ... after the cut scene at the end of the first level showing the plane going down.
I only have one tweak ... r_TexturesStreaming = 0 ... so I figured it must be that ...
As my in-game textures are set at Ethusiast that should be 2 ... I set it back to 2 and it didn't crash.

Once the cut scene at the start of the second level was over I saved the game and restarted it with ... r_TexturesStreaming = 0

I have tried it several times with ... r_TexturesStreaming = 0 ... it always crashes.
Set it to 1 or 2 and it doesn't crash.
