If you take advantage of the way the Skyrim Special Edition handles heavy mod loads to get the most of it – and especially if you use an ENB to overhaul the graphics – you’ve likely got a hit at yours Frame rate suffered. (I used Ominous ENB to give things a gritty, somber look, but it costs up to 20fps in some areas.) If that is you, the external FPS boost is here to help.
It works thanks to occlusion culling, which prevents geometry from being rendered that you cannot see. While Skyrim already offers occlusion culling, eFPS adds significantly more. Check the changelog in the description of the mod to see how many cells have occlusion windows added. That is much.
The existing project optimization mod does the same for interiors, and the two mods work together. However, eFPS is not compatible with mods that rearrange structures like Open Cities and JK’s Skyrim. The description also recommends starting a new game, as “We still haven’t fully figured out how eFPS behaves with existing game saves.” However, I didn’t notice any negative effects on my current memory level and recorded around 5 fps in Whiterun, even with Ominous ENB, which made everything dark and smoky.
This isn’t a huge improvement, but your mileage will vary. The description of the mod states: “The increase in performance is inversely proportional to the performance of your computer. If you have a very, very powerful PC, you might see only a small improvement in the FPS mod intended to improve performance especially for those who don’t have an ultra-powerful PC. “
