Hi!
i just fixed my Cod issues, wich i was having since last official release.
my FPS just had a boost, london is now flyable on about 20 fps alone. and stutters are preaty much gone. I used to have stuters all the time and some 20 fps tops, in london i got 1/3 of fps.
the reason?
apparently on the last install from scratch

steam

wrote on my conf.ini:
[window]
DepthBits =24
StencilBits=8
And when replaced by
[window]
DepthBits =32
StencilBits=16
changed the whole game for me. Im up for flying jsut wanted to leave the tip to people having desaustrous performances.
cheers
