DX11: Gugila GroundWiz RTSGugila's GroundWiz RTS application showcases real-time shader technology. In DirectX 11 tests, terrain rendering uses displacement, tessellation and higher detail ground surfaces. GroundWiz RTS is optimized for parallel computing using multiple CPUs and GPU shaders to achieve real-time performance. Procedural displacement tessellation is supported on DirectX11 compatible graphics cards. This feature adds a great amount of terrain detail, which will be extra noticeable on rocks and mountainous terrains. The amount of tessellation is user controllable and should be adjusted to the speed of graphics card. Another important aspect is procedural terrain roughness - controllable per ground layer. Terrain roughness affects lighting via normal mapping and also layer distribution. Optimized routines of GroundWiz RTS Terrain Map make it possible to render a big layer tree in real-time (16 layers and more). The current version is optimized to use graphics cards that support Shader Model 3.0 and above.
Gugila GroundWiz Alpine Benchmark Test ResultsEDITOR'S NOTE 22 March 2012: AMD representatives and their PR firm were both contacted nearly one week prior to publication of this article, alerting them to the failure of their Radeon HD 7900 series with the Gugila GroundWiz benchmark using DirectX 11 rendering. To date, no response has been received and no driver update has been posted. It remains unclear why the R7900 series functions with the DX9 version of this test, but fails in DX11 mode.
