Better
Firstly, you'll want to check what AA settings you're using. By default the RePack will use AA settings based on what graphics mode you're using (DHH
OR GraphicsMod), but will also have a Plugin called
Better AA running as well. Disabling
Better AA is usually your best bet for improving the look of hairs and textures like the fur on her coat and the weave on pantyhose.
You might also want to check which Hair Rendering type is active on the card itself - Find this at the bottom of the Hair tab in the character creator - save to update the card. Personally I tend to find that
Type 02 is better-looking and less diffused than
Type 01.
Bear in mind
some of the hairs don't render all that great at the best of times, but disabling Better AA, then adjusting the overall AA settings for whichever graphics mode you're running will get the best results. Or at the very least improve the overall look for you.
