i am looking for good graphic mod without huge fps drop any recommendation?

Have a look here: http://wiki.step-project.com/STEP:2.2.8#2.F._Conflicting_Graphics

Also, some ENB configs are supposed to be quite performance friendly.

Edit: Also check out this: http://www.nexusmods.com/skyrim/mods/20801/?

And a fairly new one: http://www.nexusmods.com/skyrim/mods/51467/?

actually enb my last priority but thank you ill look at it

I actually just finished getting all the needed files for this and compiling them. The process is much easier than Skyrim Texture Combiner which I have used in the past and STC is also no longer supported from my understanding while SMC is. I have not actually booted up the game yet to see the results. I'll be doing that tonight though.
