PC Games Hardware has graphics card benchmarks of Metro 2033. They also tested the performance with GPU Physx and DirectX 11.
According to their results the Radeon HD 5870 is the best card for the game, but there are no benchmarks with Nvidia's forthcoming GTX 480/470 yet.
A look back at 4A Games' admirably consistent post-apocalyptic shooter franchise.
Metro 2033 mechanics that would adapt perfectly to VR, and the upcoming Metro Awakening by Vertigo Games this year.
The Metro video game series started with a humble b-list title, before building a strong fanbase and becoming a pioneer in the industry.
Those number are not very encouraging. I know the game looks good, but not nearly good enough to justify those insanely low scores, especially considering that it's a linear game.
PhysX + DX11 = GPU rape.
I think the game hasnt been well optimised, wait for a patch, driver update it should be fine.
