I've got my settings working fine with what I want from my P3D, with LOD radius set to max I'm getting 34-35FPS, so I'm quite happy with what I get.

Only every couple of times I start up P3D, the LOD radius slider is set back to one step below max and every time I set it back to max, it sticks for a little while, but after starting the program a few times, it's changed to one step below max again.

 

What can I do to make sure the settings stay as I set them up?

Have you tried setting up a flight with those settings and saving it as default? Also, if you load another saved flight with different settings, that could change them.

When I've just put the slider back to max, I can open every saves flight and the slider is at max, but after restarting the sim a couple of times, those same saved flights come up with the slider set one step back.
