Hi again
I made all of this updates and patches and tried first 100 fps and later I deactivated it . Game seems still have lag
http://www.asus.com/Notebooks/Versatile_Performance/K53SV/#specifications this is my pc
with
Intel® Core™ i5 2410M Processor
Genuine Windows® 7 Home Premium
Intel® HM65 Express Chipset
DDR3 1333 MHz SDRAM, 4 GB RAM
NVIDIA® GeForce® GT 540M with 1GB DDR3 VRAM
2.5" SATA 640GB 5400rpm
I think specs are enough

What is my problem ?
NOTE : I am running with EXTREME options
I fixed my lag problem .
Also I think graphics are weird

Not smooth like I watched videos like this
http://www.youtube.com/watch?v=rNO0SbW0HIM this is beautiful . My all drivers are up to date . Everything good

But I have problems with this game only .
Later I tried shadows are off , it seems a bit better but not equal quality like others . Later when closed HDR it seems better . Why it's happen ?
