For me I uninstalled P3D a few months ago because I found Steve's DX10 Fixer - no OOMs (but I shut-down  and restart FSX for every flight), higher lod_radius, higher autogen, better fps, smoother, more compatibility etc etc

(i2600k overclocked to 4.8 - Matrox TH2Go - Saitek panels * 3 - 8gb ram - gtx580 with 1gb also overclocked)

 

 

Now I am really enjoying FSX like never before!

 

So if you could make this work in FSX that would be great because FSX has far better performance on my system so I will stay with it for many years more.

 

thats the answer. also watch part 2 and 3
