P3DV% and NVIDIA Wave Motion
Don Muskopf had a tip some time ago about AcuFeel messing up the waves in P3D. Accufeel used to be fine in this regard in FSX but I completely overlooked this and have been struggling for some time with the on water behaviour of all the flying boats and amphibians. It seemed to me that once you used real time weather injection there was a scalar magnifying the wave motion and its impact forces not to mention water drag on the hull.
So this is a DUH moment. I finally went over my notes and checked AcuFeel, because having it installed in the sim as an addon it was automatically setting wave motion etc without me being aware of it. So now it is turned off for all amphibians, floaters and flying boats and the change is remarkable, no more pounding through maginfied swells and seas!
So the fix or switch in the contact points section of the aircraft config of using either:
//always_use_avg_surface=1
or
//ignore_waves=1
is no longer required and I can safely edit them out and let P3D do its stuff. AS is a bonus here because you can get a quick real time wind report where you are (or what it is injecting into the sim) so you can easily see now if your going to go flying or not and the wave conditions now seem to mirror that better. I have still yet to see a perfectly calm see but it is ok!.
Oh another little thing about P3DV5 I discovered by chance. If you have a common or effects in an addon when the sim loads it reads these effects files into memory before it goes to the main effects folder and use the effects it has not already loaded. This turned up when I spent a day chasing a dodgy wake effect (you know the vertical to the sky syndrome) to find out that the only thing I had changed was a new addon and buried in that addons effects folder were a couple of fx wake files, corrupted it would seem. I deleted them and the sim and the effects have returned to normal. A useful tip if your looking for something amiss in this area.
