Splash sounds, Random swimming animation, flickering

[Snughs]

Hi everyone :)

 

When I'm playing Skyrim i get these weird water flickering and splash sounds, plus sometimes random swimming animation, I can say that the issue is something with FPS because its very obvious this only occurs when im running 140+ fps.

 

When i look into the nature i get maybe 140-150 fps and all the problems i mentioned occur.

 

When i look into a city i get around 110-120 fps and none of the problems occur

 

My PC Spec is:

CPU: Intel Core i7 4770k

GPU: Asus Geforce GTX 780

RAM: 2*8 gb corsair vengeance 1600mhz

MB: Asus Z87 Sabertooth
Soundcard: Soundblaster Zx

 

Any help is Appreciated Thank you :D
