The guys over at FiringSquad have posted up part one of a series they are calling [b]3D Performance with S.T.A.L.K.E.R. [/b]. As you may have guessed, they are going to see how S.T.A.L.K.E.R. runs on different hardware. Part 1 is on "MainStream Cards". [quote]Graphically S.T.A.L.K.E.R.’s X-Ray game engine is quite impressive. According to the developer, up to a million polygons can be on-screen at any one time, and the game sports the latest eye candy effects, including HDR lighting, parallax and normal maps, 3.0 pixel/vertex shaders, per-pixel lighting and soft dynamic shadows. In fact, the game is so demanding that many card owners with DX9 cards like the GeForce 6800 and Radeon X800 have been forced to play the game in DirectX 8 mode. This is because the game’s dynamic lighting model performs so many calculations it can bring many DX9 cards to their knees: get to aggressive with the graphics settings, and you can bring a modern GPU like the GeForce 7900 or Radeon X1900 to a sluggish crawl.[/quote] Check out the full article [url="http://www.firingsquad.com/hardware/stalker_mainstream_3d_performance/"]here[/url], and see if your card can really stand up to X-Ray.
