I also use Kurasoberina Primer HD Default Skin and with HD Specular Default Replacement. I'll try the HD skins and see how it goes Thanks! I use navetsea model default and the barbie you are real by Buhudain and I'm not satisfied with how it looks. If you like the No Glow mod, there is a link to have that separate and you could probably combine it with the HQ mod by aWT (first link) that allows you to turn it off and on. The second link (the mod that I currently use HQ+No Glow) overrides your GraphicsRules so you will need to edit it again in order to keep your card recognized. The first link gives you the option to turn it off and on. But it will add extra stress to the game.
You can use it for constant game play if the PC can handle it (yours would) and if the texture resolution isn't set too high.
HQ mods are used for sim picture taking and you won't see too much of a change unless you're using HD create a sim content (example: skin). I have now switched over to this HQ mod and it's paired with a 'no glow' mod.
