Amnesia lighting, can't see much

[midflame222]

I just bought Amnesia: The Dark Descent from Steam, And when I play the game I see this




(This is Gamma on the highest setting, I'm playing on a low-end computer at the moment, so I play on the lowest settings)

And I'm sure from watching videos of this game that It's not supposed to look like this, anything that can help me? Here are my specs

Processor: AMD Athlon 64 X2 Dual-Core processor TK-55 1.80 GHz
Ram: 958MB
Graphic card: NVIDIA GeForce Go 6100
