DX11: Metro 2033
Metro 2033 is an action-oriented video game with a combination of survival horror, and first-person shooter elements. The game is based on the novel Metro 2033 by Russian author Dmitry Glukhovsky. It was developed by 4A Games in Ukraine and released in March 2010 for Microsoft Windows. Metro 2033 uses the 4A game engine, developed by 4A Games. The 4A Engine supports DirectX-9, 10, and 11, along with NVIDIA PhysX and GeForce 3D Vision.
The 4A engine is multi-threaded in such that only PhysX had a dedicated thread, and uses a task-model without any pre-conditioning or pre/post-synchronizing, allowing tasks to be done in parallel. The 4A game engine can utilize a deferred shading pipeline, and uses tessellation for greater performance, and also has HDR (complete with blue shift), real-time reflections, color correction, film grain and noise, and the engine also supports multi-core rendering.
Metro 2033 featured superior volumetric fog, double PhysX precision, object blur, sub-surface scattering for skin shaders, parallax mapping on all surfaces and greater geometric detail with a less aggressive LODs. Using PhysX, the engine uses many features such as destructible environments, and cloth and water simulations, and particles that can be fully affected by environmental factors.
NVIDIA has been diligently working to promote Metro 2033, and for good reason: it's one of the most demanding PC video games we've ever tested. When their flagship GeForce GTX 480 struggles to produce 27 FPS with DirectX-11 anti-aliasing turned to to its lowest setting, you know that only the strongest graphics processors will generate playable frame rates. All of our tests enable Advanced Depth of Field and Tessellation effects, but disable advanced PhysX options.
Cost Analysis: Metro 2033 (1680x1050)
Test Summary: Metro 2033 is a tough cookie for a single video card to crack, in our tests the single cards only just get some acceptable numbers. This is another game that really benefits from a CrossFire setup, thus enabling you to increase the visual settings without worrying about FPS. The HD6850 CrossFire configuration gives an average 45% performance increase over a single card which equates to 90% scaling at 1920x1080. The HD6950 CrossFire setup gives on average 49% extra performance over its single card contenders, this equates to 98% scaling at 1920x1080. In our cost analysis you will see that the cost per frame rating of the HD6850 CrossFire setup and the HD6950 CrossFire setup is very high compared with the single card results.
