MSFS and Process Lasso

Not sure if anybody has seen the same, but since updating to the latest verison of the Fenix Process Lasso is no longer holding affinity when switching windows. What I mean is that with any other aircraft loaded into the sim, if I change my window of focus away from MSFS and to another application (i.e. Chrome) MSFS remains on my X3D cache cores and performance doesn’t miss a beat.

If however I have the new Fenix loaded and I alt-tab to another window MSFS performance drops considerably - Looking at task manager it seems that with the Fenix loaded if I alt tab out of MSFS it stops using the X3D cores and falls back to the regular cores.

Odd behavior - 100% repeatable. Strange that it only happens on the Fenix. I’m guessing maybe something to do with the external apps that it runs…

Anybody got any ideas or seen similar?
