So basically most of them. I just go for the main mods - things like "Realistic paper" have too little impact on gameplay. Plus, the more mods installed, the greater the risk of instability and it takes much longer to track down the problem.
Currently downloading the Skyrim HD update.
Best shader mod is still ENB http://enbdev.com/download_en.htm
It doesn't just change the colours like the other shader mods do. Rather than simply adding or changing Skyrim's post effects, it completely replaces it. You now get better shaders (especially for skin), some sweet sky effects and a sort of fog that increases the sense of depth wherever you go (just like how artists use lighter colours and less contrast in the mid and far ground).
The most noticeable change though is colour. This one brings out the colours of all the textures. It's quite glaring at first because it makes the game much more colourful, but in reality it's more realistic and the game becomes more interesting to look at.
Texture mods won't cause instabilities. (like 99% of the time)
BTW, I've just realised Serious HD Retexture Landscape Skyrim looks terrible in game.
AAARGH, my EYES! GET THAT OUT!
I think it looks brilliant, i really notice a positive difference.
Just look at the screenshots comparison above, see how the distant textures look like.
I do see it looks terrible in your screenshots, but i do not see it in game, maybe i just don't notice it. Screenshots really do not do this game justice.
btw, that combat mod doesn't work for me, not too bothered as i only wanted it so that backstab had 100% chance of a finishing move.
Your textures look terrible, you must not be using SKYRIM HD Mod
It's still in alpha and, as you can see, The force is a teeny bit OP but he's going to tweak them and make them quest related / rewards which would be better.
Cheers Krugga!
HD Skyrim Textures is top notch, so doubtful i'll remove that but i'll add yours as a second option
