Hi there.
My advice would be, ofcourse if u have few bucks to spend, get a facetrack or freetrack setup. It cost is just around 30$ with cam and stuff and as i read u are an engineer so u should have some manual skills aswell
Build a clip/cap get a PS3eye Cam and u wouldnt have to worry about head movements
Also:
My rig is
Phenom x2 965 be almost @ 3.8
Sapphire hd 7850 2gb a bit OCed
8gb ram
7200rpm hdd
and i get a lot of stuttering and micropause. No matter what ANGELS am i. I just dont get this game.
I tried to fix this but without any success it happens with low medium and high settings with and without AA. Only difference i see is when i lower buildings details and forest.
My Vram is rarely exceeding 1.5gb
Also i noticed that from time to time VRAM is just going "empty" and this is where the micropause comes in... Most annoying during dogfights..
Remember to increase ur "contacts" draw distance
Have a good one
