Damnnn those look way sharper than mine. They look really nice. Are you using the default Lumasharpen settings or do you have a custom set up? I think I might have lumasharpen on but I'll try the adaptive one too. Thanks!
Yep TXAA is definitely better for aliasing but noticeably softer.

Here are my Lumasharpen settings:
#define USE_LUMASHARPEN 1 //[LumaSharpen] //-LumaSharpen : Sharpens the image.
//>LumaSharpen settings<\\
#define sharp_strength 0.85 //[0.10:3.00] //-Strength of the sharpening
#define sharp_clamp 0.025 //[0.000:1.000] //-Limits maximum amount of sharpening a pixel recieves - Default is 0.035
//>Advanced sharpening settings<\\
#define pattern 2 //[1|2|3|4] //-Choose a sample pattern. 1 = Fast, 2 = Normal, 3 = Wider, 4 = Pyramid shaped.
#define offset_bias 1.3 //[0.0:6.0] //-Offset bias adjusts the radius of the sampling pattern. I designed the pattern for offset_bias 1.0, but feel free to experiment.
//>Debug sharpening settings<\\
#define show_sharpen 0 //[0:1] //-Visualize the strength of the sharpen (multiplied by 4 to see it better)
#define LumaSharpen_ToggleKey RFX_ToggleKey //[undef] //-
If you're not using FastStone (you should) or if there's something hazy going on with FastStone image converting/downsampling this is a perfect way of getting those crisp shots come out the way they're supposed to be;
Set Lanczos 2 as the filter when resizing
When saving the image as JPEG set Color Subsampling - disabled, Optimize Huffman - off, enable Progressive and use a quality of 98%-100%.
Those are the settings I use (if I don't convert to PNG) and the images come out clean everytime.
