Hi All! Long time reader, first time poster. I found a mod from Fallout 3 that, when paired with SkyBoost made a huge impact on my framerate everywhere. My system isn't the best, but it is not bad. When I play Skyrim on High settings (what the setup sets for me), I am lucky to get 25 fps. I also get lots of slowdowns in caves, near waterfalls, etc. In any event, I found Fallout Stutter Remover, which, when paired with Skyboost brings my game up to roughly 38-41 fps on average. I have started adding mods without a major fps hit. I get periodic lags, but nothing like before. I have even gotten it above 60 fps in places. That was unheard of until now. I have dialed back on a few settings and am not on Ultra, but I am in a spot between High and Ultra based on some of my ini settings and the setup sliders. The mods I have right now are: Skyrim HD Female muscle mod Quality World map Better Gold Categorized Favorites Enhanced Night Realistic Lighting without Post-Processing Realistic Water Textures SkyUI Xenius Character Enhancement. I plan on adding more, but so far, I am really impressed. I don't know if this will be helpful for anyone else, and it is a try at your own risk, but it may be worth it to get some playability back. Good Luck!!
