#10 Skyrim Enhanced Shaders
Download it here.
First and foremost is the Skyrim Enhanced Shaders by tapioks. Built on Boris Vorontsov's fantastic ENBseries shaders, Skyrim Enhanced Shaders adds new visual effects into Skyrim. It makes the whole game look a lot less dull and lifeless by adding more vibrant shades, high dynamic range lighting (HDR), adaptive bloom, sharpening, and a framerate limiter.
In particular, the FPS limiter helps players with lower-end configurations by providing a consistent framerate. Everything else just makes the game look nicer.
For the best results, grab the FX Beta version of Skyrim Enhanced Shaders—and don't forget to remove the custom sunglare that comes with it, which detracts from the overall visuals.
