I was previously using Freetrack with SimConnect interface to do headtracking in FSX. I saw a couple videos on YouTube with head shaking effects and nice camera views from EZDok, so I figured I'd do the switch and give a try to this nice add-on. I installed EZDok and noticed I did not need to use SimConnect interface anymore, but I can simply use the trackIR interface from Freetrack to do head tracking through EZDok. So far so good. During a quick test flight, The headtracking stopped working. When I alt-tabbed, there was tons of windows with error message concerning an access violation in npClient.dll. I searched on forums and figure it was something buggy between Freetrack and EZdok and multiple persons suggested to switch to FaceTracknoIR. Someone made a module that uses the 3 IR LEDS to do the tracking instead of the facial features to do the tracking, which is much more precise, just like TrackIr and Freetrack do. It is also much more stable and works better in my opinion. Switching to FacetrackNoIR was a good thing to do. Freetrack was riddled with bug and hasn't been developped since 2008, so it's a good thing I put this one behind. But even when using FacetrackNoIR, I still get frequent headtracking stop. After about 5-10 minutes in game, the tracking stops and resets to the center position. I can't use any of the EZDok features (middle mouse button and drag does not work to look around). If I alt-tab, kill EZDok and restart it, it still does not work. If I kill and restart the TrackIR.exe dummy from FaceTrackNoIR, it does not fix the issue. I need to kill both EZDok and and TrackIR.exe dummy, then restart them both, then I can use EZDok again and head tracking resumes. I found dozens of thread with people having issues with FreeTrack and EZDok. I haven't seen much threads where people have issues with EZDok and FacetrackNoIR. I tried killing my antivirus and killing any other windows processes I do not use. Nothing solves my issue. Anyone has a clue about what is going on here / suggestion about how to fix? Any help will be greatly appreciated.

Thanks to all of you for your answers! Yesterday I worked on improving my frame rate and it believe I got everything running smoothly now.Previously, locking my FPS to 30 in FSX, or with an external limiter, I was getting 30 FPS, but constantly stuttering and oscillating between 20-30 fps. What I finally did is follow these tips: http://forum.avsim.net/topic/369500-adaptive-vsync-30fps-new-levels-of-smoothness-in-fs9x/ The title of the article says "Adaptive Vsync", but really, this is not what they are doing exactly, In summary, I use NVidia Inspector to set the vsync rate to 1/2 the refresh rate, and set the vsync method to "Standard" (not "Adaptive"), Then I lock the frame rate to 30 in FSX. This made the sim run at 30 fps smoothly 99% of the time. It sometimes stutters to 25 momentarily when I initially load an area, after starting the sim, but it ramps up to 30 fps stable quickly. I did not have to lower the detail of the Realair Lancair Legacy to achieve this. This is really a gorgeous plane and I can't wait to do another flight with it. Unfortunately, I encountered some other graphical issues, but I believe this is another matter and I will start a new thread for this. Cheers!

Thanks for the detailed response! I will try a lower quality settings of the Lancair Legacy and will post my results here. I did not try, as the Realair user manual says this reduces de functionalities of the cockpit. Right, this is what most people say. Unfortunately, this is not what I am seeing. I've checked you PC setup and it looks a bit lower-end than mine. I wonder why I get such a drop here! Do you have your frames locked, if so, at what fps? How is your simulator setup for the autogen/traffic sliders? While I agree that flight simulator is not very optimized to use the newest PC ressources efficiently, I do find it surprising to get such an important FPS drop by just switching to a higher polygon aircraft. With the default aircraft, I can max out autogen, traffic density, view distance and more, and still get a good smooth 60fps when I cap the frame rate using an external limiter. I simply find it shocking that by just switch to this aircraft, even if I turn off autogen/traffic/VSync, my computer struggles to maintain 25-30 FPS, even if I lock frame rates to 30. This is an important drop, while most people mention they barely see an FPS drop with this plane! I will try other addon planes, any suggestions of high quality general aviation planes that are easy on the frame rates? I'd like to compare with what I am getting with the Lancair Legacy. Thanks.

Hello fellow simmers, I just overclocked my PC to a stable 4.1Ghz. I also uninstalled FSX and every addons I have, then reinstalled from scratch. I then proceeded to tweaked my graphic settings, went through Bojote's fsx.cfg tweaker as well. Step by step, one by one, I reinstalled my add-on, making sure to run my test flight each time and monitor the FPS to see if any addon cause an FPS drop. Before reinstalling any addon plane or AI traffic, I'm runnning a steady 60 fps, locked by an external frame limiter. I bought the Relair Lancair Legacy, as this seems to be an extremely polished payware plane, and most people says they have close to no FPS drop after installing it (some reports a 3-5 fps drop... I could live with this, especially since when I unlock the frame rate, I get about 75 FPS.). I was shocked to see my FPS drops to about 25-30 when I switched to this aircraft! Even with no AI traffic, no VSync, in an uneventful airport (CYQB), same setup I used to test any other steps of my installation. Switching back to a default FSX plane give me back my FPS. Any suggestion on how to fix this? Anyone ever experienced something similar with this plane?
