--- Comment #17 from Bernd Kosmahl beko@maxr.org --- I made an api trace as well. Perhaps it's helpful. The game works just fine for me:
OpenGL renderer string: GeForce GTX 470/PCIe/SSE2 OpenGL version string: 4.2.0 NVIDIA 304.88
http://beko.maxr.org/MetroLL.trace.tar.gz (674M) http://beko.maxr.org/MetroLL.trace.tar.gz.sha1
I started the game, changed the "gfx settings slider" to MAX and loaded a savegame. After that I quit the game.
