Ok. Some like the mother and others like the daughter. I have tried P3D ver.3.4 for about a month, and I found that P3D have some strange drawbacks.
Somtimes very blurry textures (slow update) and the same with autogen. I like P3D , but I might return to FSX
I have FSX and P3D installed and for the moment I'm testing out different tweeks.
Most of the FSX cfg setting can be used on P3D and visa versa.
Under nearly the same setting and conditions (Aircraft, weather, scenery, Nvidia setting and so on), I found that they both have almost the same impact on my CPU/GPU.
P3D gives abit more stutters and FSX loads textures and autogen faster.
