Shadow Quaility killed my FPS

[Tensu_Makadi]

All right got a new desktop been spending the last couple of months touching it up and working on my old laptop testing mods and deciding what I want to use for a play through on this new machine since it can handle more but I don't feel like trying to figure out mod conflicts during this playthrough... All my mods have had no conflict and no real performance losses on my laptop with the exception of the two I didn't test on my laptop SMIM and SkyrimHD 2k textures my laptop couldn't handle those but this new desktop could, I did test them and got some fps drops in places but nothing noticeable, but after installing Climates of Tamriel and ELFX now certain place most noticeably bleakfall burrows I get mind numbing fps drops from what was 60-45 fps down to 5. After some testing I have found the cause and it is in shadow quality it will run fine at high quality no drop other then the same as I saw when I ran with just SMIM and SkyrimHD but bump it up to ultra high and bam fps drops to 30-45 in most dungeons 5 or lower in places with a lot of shadows and in outdoor areas even if I see no shadows random spots will occasionally drop to 15-30 fps. I would like to run everything on ultra if possible and can even live with 25-30 fps but especially the areas with fps of 10 or below well it just becomes literally unplayable. I really like ELFX and Climates of Tamriel not sure how they run fine at ultra on my laptop but not my desktop and I could even live with out ultra shadows if someone could tell me how to remove those bizarre lines from characters when standing in certain shadowed areas.

Side note those 4 graphics mods are the only mods I have installed right now. I was expecting some hit with them and wanted to find out if it was something I could live with.
