I am involved with IL2/FB Testing. At present I am running a test IL2/FB SFS file that contains specific TrackIr fix routines in it.
Can you contact me via Email ref this subject.
I need a little more information to test this correctly.
My setup is TRKIR3Pro Vector. In Standard FB I have noticed a small issue that may be related.
At the 3 and 9 oclock positions I get a little view wander of around +- 2 degrees or so at about 10hz, with my head motionless. So far adjusting Smoothing/Light filtering has no effect
