Skyrim bug. Water textures flickering, Screen stuttering black, and Animals flying into the sky
Solution 1:
I have had the same problem myself, exact same symptoms. For me it was because i turned off v-sync, i suspect one of your mods does that.
But if your mod turns off V-sync its important to also use the FPS limiter mod from nexus (simple download and drag 2 files into skyrim folder). I noticed that mod is not on the list. Most programs that limit FPS dont actually solve the problem, but the FPS limiter from nexusmods does.
