New P3D tweak, OPTIMIZE PARTS

Recommended Posts

פורסם

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

Sound like instancing to me


I'm really surprised no one saw this until now though , it should help mainly in cases which you have many duplicated objects without loosing too many performance , and even more surprised that P3D developers didn't enabled this by default


From my experience , in Xplane though , this will help with creating a MUCH MORE denser scenery in terms of objects some cases even 2X more frames.

I was aware of this fix from day one. it wasn't brought in this forums as there are hardly if any P3D users here.

in addition I personally saw no difference in performance in FSX nor in P3D with this settings, but yet heard of increase cases reports of CTD

i think for powerful system this tweak will be less noticeable


most of you who commented on this not working or unnoticed changes (i know some) have high end desktop systems


i use a laptop many times to test where the tweak does show its colors, i think this is also NVidia related tweak
