Just today while fooling around a bit, I noticed that in P3D I have less or almost no FPS drop when mouse is over and off the sim.
I read on NGX support forums from Tabs, that FSX was coded like this and there is nothing they can change to make it better. It happens with any aircraft, even default, or so they say. The effect is most noticable with the heaviest aircraft, for example NGX or Turbine Duke, both which are pretty FPS heavy.
However, while comparing some performances in FSX and P3D, I had a situation loaded, which shown me 36-37fps in the unlocked state, in both sims.
HOWEVER, in FSX, these FPS dropped to 30-31fps while mouse was over and risen again when mouse was off the FSX to 37. Now, in P3D, they stayed at 36-37fps, with both mouse over and off!! This alone is for me, worth the usage. While currently the 1.4 doesn’t give much (if any) FPS boost, it DOES seemingly fix this. At least this is my preliminary test and fast conclusion.
I would like to know: did anyone experience anything similar?
