roughly 50% FPS Decrease between Takeoff and Landing

Drastic FPS decrease at TouchDown without any recovery, starting with OAN zoom in and stays low after that

With the A350-900 the FPS gets a roughly 50% decreased  Approaching and Landing. Especially AFTER hitting the ground at landing my 58 FPS went down to 30 FPS and did NOT recover anymore. And this was with TLOD 75 during approach, landing and on ground taxiing!! 

I have already mentioned this in my previous other posts and not seen any reply. Maybe it hasn´t got an attention. I suspect some issues with the ND and navigraph integration, but this is not for sure of course.

Today I started at HAAB Addon scenery flying to OMAA (IniBuilds) with 65FPS in VR! TLOD set to 75. While taxing my FPS went a bit down to FPS 58. During takeoff and climb to 41000 Feet FPS increased from 58 to 68/72. During approach it got a bit decreased while nearing ground but it did stay above 58 FPS.

Immediately at TouchDown, exactly in that moment, the OANS got loaded in, my FPS went down to 32/35 and stayed there! It´s important to note, that I preloaded the arrival airport OAN at CRZ. So at touchdown the only thing happening at my ND was the Zoom. But even after zoom was done, automatecally, my FPS stayed at 32/35 and never recovered. 

I taxied to the gate and shut the aircraft down, with 35 FPS.

Went to the main menu, started a new flight with exact the same plane at OMAA, same gate, gate 610, and my FPS started with 65 to 68 FPS. Starting APU and turning on the batteries did not have any influence on my FPS, it stayed between 65-68 FPS.

Something must be wrong with the code. This is not only happening at these airports but at any airport and any landing after a minimum of 2 to 3 hour, or longer, flights. Competitors airplanes do not have these FPS decrease at touching down. 

Navigraph charts still having inpact on performance during cruise after roughly 1,5 Hour in flight

I use navigraph subscription and navigraph enroute charts. In this case, started at HAAB, I used after the climb out, the IFR High chart during climb and cruise. After roughly 1,5 hours I noticed some lagging while panning my VR HMD (Varjo Aero). I checked my FPS and saw it went down from 68-72 FPS to 55! 

When I clicked on the OIS Navigraph "Zoom Decrease" icon (minus=zoom out) exactly ONE time, FPS immediately recovered to 68-72. This is a phenomen wich occurs everytime after roughly 1,5 and 2 hours in flight.

People who cap their FPS may not notice it. But when you let your system push out maximum FPS, like I did in this flight, you can see how after a certain amout of time (as mentioned between 1,5 and 2 hours) FPS decreases quite dratsically and panning in VR gets a bit of a lag. Latency goes down the drain. 

Please consider

I am not sure if this also influences the above described touchdown issue with FPS decrease. But these 2 findings making cruise and especially landing having less fun. 

OAN loading in at touchdown is already causing stutters, as many people mentioned already. Landing is the most exciting part of a flight for most of us. It is also the performance heaviest part, because nearing an airport causes lots of materials to load....and OAN do have to much negative impact on TOP of this.

But a 50% FPS decrease wich does not recover, is not acceptable. The only ADDONS I used in this flight where HAAB (bought at IniManager and OMAA from your company developped). 

Please take a note of this and parse it to the team to have a serious look at this. My immersion and satsifaction would increase a lot if you are able to make this more usable! I have a top notch system build.....others will struggle much much more for sure.

And I do read this landing FPS decerease issues on many FORUMS and Posts. 

Thanks in Advance and THANKS you delivered this beautiful peace of "aviation". I hope you make it better and more robust.
