Multisampled SDF for text rendering (4x AA with single texture lookup, 16x with four lookups)
View multisampled_font_sdf.glsl
// Multisampled SDF for text rendering (4x AA with single texture lookup, 16x with four lookups)
// It is for SDF text rendering with 16x antialiasing with only four texture lookups, where an
// SDF texture texel in turn also has four individual SDF values in the RGBA color channels in
// a 4-Rook/RGSS sampling pattern.

So here's a pretty neat thing, I use VHD's to organize the space on my computer. You can too!

BeRo1985 / compute shader NVIDIA driver 347.09 WHQL slowdown bug

SDSM compute shader NVIDIA driver 347.09 WHQL slowdown bug
View compute shader NVIDIA driver 347.09 WHQL slowdown bug
With version 347.09 WHQL tooks my SDSM tighting compute shader whole 70 ms per frame instead with the old verson 344.75 under 1ms (circa 0.7ms) on my GTX970.
See sdsm_reduce_tighting.glsl here, the $-stuff is my own preprocessor.
I'ver tracked to the "((lLinearZ >= reduceDataPartitions[lPartitionIndex].x) && (lLinearZ <= reduceDataPartitions[lPartitionIndex].w))" (in sdsm_reduce_tighting.glsl) comparsion down, but really just the comparsion itself, because:
70ms per frame:
if((lLinearZ >= reduceDataPartitions[lPartitionIndex].x) && (lLinearZ <= reduceDataPartitions[lPartitionIndex].w)){
minBoundsSun[lPartitionIndex] = min(minBoundsSun[lPartitionIndex], lSunLightSpaceCoord.xyz);
