Strange behavior

[331BK]

Hey,

 

since i moved from orbx ftx .... to gep3d and utx i have a strange behavior.

 

sometimes when i start the sim i gave only 3 - 5 fps cpu and gpu are at nearly idling ( cpu 20 %fps gpu 3 - 17 %)

uaualy when i then change the cloud density to somerhing different  the frames go up to 30 and more ( monitor is at 30 hz). and everything is smooth.

i then moved to an outsight view and bamm again 3 fps.  Changed density and back to 30 fps.

strange thing is when the frames are back at 30 i can change the density slider back to max and nothing happens still 30 fps.

is it possible that something from orbx is left and causes this?

i use skyforce 3d, asca, as16 , envtex and envshade.

test was done at flytampa loww with qualitywings 787 at night.
