So, since the last time I played Metro2033 I got a widescreen monitor (acer G235H), and a new graphics card (GTX 550), and I've discovered Metro2033 won't render widescreen properly. Everything looks stretched. Obviously after a bit of googling I discovered this was a problem when Metro2033 was released that was promptly patched; steam assures me my copy is up to date, but there's still obviously a problem.
