graphics fps cpu stutter

[LTcommander]

gtx960 ,i5 6600 unparked and high prio at 3,2 turbo 3,9 , 8 gb ddr5 ram, ssd, opentrack

 

whatever i change in nvidia ,ingamesettings etc. i sometimes get heavy stutters near ground when clouds or smoke involved (no difference between ultra or low !!!! ) fps dropping from synced 60 to around 40; unsnced fps tops at around 140

 

im lost here because experience says my rig could run it stable and more important fluid, (i dont really care for eyecandy but like said before it doesnt make a difference if ultra or minimum)

 

am i allowed to blame dx9 ? or is the i5 6600 that bad and causing the performance probs ? any guess ?

 

dont forget the stutter is the problem !
