ground lag stuttering(beta patch)

[pupo162]

So, m havign this huge issue with my current installation of alpha/beta patch.

i have 70+ fps over England (60 with vsync) yet, dispite my fps i see the ground lagging and stuttering. which is strange because my bullets and pother plaens move fluidly over this stutering land.

so picture a stable fps and the game moving at 60+fps, but the ground only moving itself at 15-20 fps?

to reproduce this issue, fly over england at 500 meters max, and look down to the ground, the easiest view is looking at the trailing edge near the cockpit (low5/7 o clock) zoomed in, and watch stuff passing below you stutering.

settings:
maxed out graphics.
7870 i5 2500k 8gb ddr3

tried to play around with settings, specially vsinc ssao and AA. no joy.
