The setting "Texture filtering - Negative LOD bias" - "Clamp" is completely removed from the driver, but still exists in the control panel as a placebo. The setting "Texture filtering - Quality" - "High quality" should apply AF to textures with negative LOD, but this option is partially broken, so it does not do this. Of these the the following are now ignored in newer drivers:Īnisotropic filtering doesn't apply to some textures.Īnisotropic filtering doesn't apply to textures that uses negative LOD. PS_TEXFILTER_NO_NEG_LODBIAS (Texture filtering - Negative LOD bias) PS_TEXFILTER_ANISO_OPTS2 (Texture filtering - Anisotropic sample optimization) PS_TEXFILTER_BILINEAR_IN_ANISO (Texture filtering - Anisotropic filter optimization) PS_TEXFILTER_DISABLE_TRILIN_SLOPE (Texture filtering - Trilinear optimization) QUALITY_ENHANCEMENTS (Texture filtering - Quality) The changes were (paraphrasing from info kindly provided via PM on nvidia forum):Īs of 400 series Geforce Cards and associated nvidia drivers there arose excessive pixelation on some textures when scene is in motion in old DirectX 9 games.įor card lower than Fermi based (pre 400 series), driver reads following options: Several things changed in drivers with the advent of 400 series nvidia cards (maybe amd though I've not confirmed) that otherwise made older games look worse by default. So i'd like to make an old game look better on newer video drivers using modified d3d9.dll which will be in main games parent directory.
