High dynamic range means that you’re using a larger range of possible values, for instance 10-bit (0 to 1023) versus 8-bit (0 to 255). HDR rendering performs lighting calculations in high dynamic range, hence the name of this rendering method. Thanks to that, you can use a low-polygon model and generate more triangles on the fly to produce a much smoother final mesh.

Tessellation makes it possible to repeatedly subdivide the geometry into a finer mesh.

The key point of tessellation is to generate smoother surfaces than would be produced directly by the original mesh. A crucial parameter is the TessFactor, which controls the degree of a fineness of the 3D mesh, i.e. For real-time rendering, an original dataset is tessellated into triangles, allowing for dynamic detail to be added and subtracted from a polygon mesh and its silhouette edges. Tessellation is a computer graphics technique used to manage vertex sets and divide them into structures suitable for rendering, enabling graphical primitives to be generated on the GPU. Today we’re going to show you how tessellation, high dynamic range (HDR) rendering and depth of field (DOF) affect both image quality and performance. In our previous articles on graphics options, we discussed and compared different anti-aliasing methods, anisotropic filtering, screen space ambient occlusion (SSAO) and hair simulation effects. Now it’s up to the gamer to decide whether to enable one for the visual difference it affords, even if it does drive down overall performance.

On the other hand, there is a range of other options that can notably alter in-game graphics. Some of them, like anti-aliasing and anisotropic filtering, are essential to achieve high quality image and should be disabled only as a last resort. To achieve a perfect balance between the two, it is usually necessary to adjust certain graphics options. Tweet Ever since the PC gaming era began, games have always aimed for the highest possible image quality and the fluid gameplay ensured by high framerate.
