This patch script allows to boost the OpenGL anisotropic filtering performance optimization algorithm, which has been introduced in the Detonator 28.90. By default the OpenGL driver uses sophisticated polygon rejection algorithm and disables anisotropic filtering for certain textures, filtered by non-primary TMUs, when the driver detects that it has no major image quality impact.
Unfortunately, this algorithm is ignored in the applications, which can override default degree of anisotropy. The algorithm is also totally ignored on Quadros.
AnisoBoosterOGL patch removes all these limitations and allows to extend the range of applications and boards, which can gain boost from the performance optimization mode. The patch script also allows the OpenGL driver to use the polygon rejection algorithm for the primary texture mapping unit too and boost anisotropic filtering by up to 10% with no major image quality impact.
