by now this has been established and confirmed as a valid new tweak that improves performance significantly on P3D platform
since no one brought it up here; i thought I’d bring it to everyone's attention
This attempts to optimize multiple parts of a model by combining them into fewer meshes if possible
If you have a complex model that is not already optimized to reduce draw calls etc, this will attempt to do that for you
open your Prepar3D.cfg, find [sIM] section and add the following lines
[sIM]
OPTIMIZE_PARTS=1
[Weather]
OPTIMIZE_DENSE_CLOUDS=1
above tweak were tested on my machine (Win7) with an avrage of 10FPS gain
go test
