myT	8c32b986f6	added r_mapGreyscale and r_mapGreyscaleCTF	2022-04-23 23:38:06 +02:00
myT	7412c4b373	added r_alphaToCoverageMipBoost and did some other changes to A2C ... - r_alphaToCoverageMipBoost scales the alpha value based on the current texture LoD this prevents the "fading with distance" effect - mip 0 dimensions are tested to decide whether contrast boosting around 0.5 is enabled this is to deal with high r_picmip configs - improved algorithm for excellent sharpness and minimized temporal artefacts - GLSL 4.00 is required for the GL3 backend to use A2C (for textureQueryLod)	2020-07-07 03:49:52 +02:00
