I spent over 100 hours playing Enderal, and noticed one thing: There is much more high res textures, vegetation, cool lightning and other fancy stuff here then in Skyrim, but FPS in Enderal is very stable compared to my modded Skyrim. In Enderal FPS is about 40 (sometimes goes to 60), but when I try to achieve same looks in Skyrim (with same settings), it falls to 20, and game becomes "ugly". Is there any way to bring Skyrim close to Enderal (without ENBs), but with same performance? And yes, I read "Credits.txt" and used that mods.
