Comment # 17 on bug 71239 from Bernd Kosmahl

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)

I started the game, changed the "gfx settings slider" to MAX and loaded a
savegame. After that I quit the game.
