so i have been looking everywhere for a discussion about this problem or at last a fix.
but i found nothing, so i thought i just ask the game developers for a reasoning behind this.
I have 

• a 75 Hertz Monitor.

• Intel® Pentium® Processor G3240 / 3M Cache, 3.10 GHz

• NVIDIA GeForce GT 710 Graphics Card
• 6 GB of RAM
• 64-Bit OS

Note : the problem occurs while playing on offline mode / single players servers

the game is not displayed as 60FPS as the debug menu says, it feels choppy and not running well
the characters seem like they jumping not moving
V-sync is turned off, Small Textures and NetBook Mode are also turned off


help would be really appreciated, i have been looking for a fix for around 5 days now.
tried everything but the problem still persists to occur
