E-Jets V3 FPS Drop/Stutter in P3D V4.5


Recommended Posts

I previously owned the Feelthere E-Jets V2 for FS9 and FSX so was pleased to see that V3 was a big upgrade to the interior and exterior. Unforunately, I have yet to get it to run smoothly. The FPS drop roughly every second to around 13 FPS and will otherwise reach around 80 without FPS lock on. I've read just about every thread on here and other forums and the majority point to the Windows Defender fix which I have tried to no avail. I have also tried:

  • Running EmbSetup.exe as administrator, with and without compatability mode for Windows 7 and 8 (was a fix for V2 from memory)
  • Various combinations of settings with regard to VSync, FPS lock, texture, triple buffering, AA, etc in P3D settings
  • Various combinations of settings within Nvidia control panel and Nvidia Inspector (eventually left Inspector to default except 30 FPS lock and Prefer Maximum Performance)

P3D runs at 80+ FPS and is smooth as silk with default aircraft. I'd be happy to run the E-Jet at 30 FPS, even if it means running on low settings. I am running a clean install of P3D V4.5 with no other addons. My only change to the P3D config is FIBER_FRAME_TIME_FRACTION=0.10. I previously ran addons such as PMDG 737NGX smoothly on FSX using VSync at 1/2 refresh rate (60 Hz monitor), although I understand that won't be possible on P3D. I am running on a relatively low-end system (laptop) but have been able to run FSX among other games in the past without any major problems at reasonable settings. Windows is up to date, as are all drivers including Nvidia (466.27). Specs are as follows:



Intel i7-4720HQ @ 2.60 GHz


Windows 10 Home 64-bit


Any advice would be greatly appreciated.
