FSX vs P3D

Major differences between Lockheed Martin’s Prepar3D and Microsoft’s FSX

These are the facts, live with it:

  • P3D uses the same soure code as FSX, but all the rest is completely rewritten to benefit max use of modern technology. For example:
  • FSX uses default DX9 and only has DX10 preview which is very buggy, and is only recommended to use with Steve’s dX10 Fixer
  • P3D uses the current DX11
  • P3D is alot more Stable than FSX, no sudden stop responding
  • P3D has better Memory usage than FSX, although both are still 32 bit, OOM’s are still possible
  • I encountered many when using fsx, and none so far with P3D
  • P3D uses volumetric clouds & fog
  • P3D has better shadows & lighting effects
  • P3D has constant updates , unlike FSX
  • P3D is CPU & GPU dependant, so if you got a very power cpu & graphics card you will get more FPS in P3D than in fsx
  • FSX runs 80% on CPU
  • P3D supports nvidia SLI , FSX doesn’t
  • FSX requires alot of tweaking
  • P3D requires only 1 tweak

So if you got a powerfull recent system or new to flightsimming and you dont know which one to choose, go for Prepar3D.
