a350-900 Performance loss while Landing

[aadi_sim]

Hi Ini team, 

I have been flying the A350 on a long haul route HKG-SFO ( Inibuilfs VHHH & Flightbeam KSFO) and I have found a weird issue of the FPS dropping to like 10-20fps on final approach. I dug around and found that the “Fauna” option off seems to making a bit better( I realise this is an MSFS option) giving around 15-20 fps on touchdown but the aircraft in general becomes a stuttery mess. General performance on the flight has been quite good with consistently 60+ fps but during final approach ( below 200 feet) it seems to all disappear. Interestingly, on the couple of flights I have done, I noticed that switching to the external view seems to be fine and the performance remains at around 60fps. The moment I switch to the cockpit view for approach the FPS drops by around 15/20 frames and stutters a lot without any recovery until I have fully stopped the aircraft at the gate. This seems like a weird issue with the cockpit view causing this ? Let me know if you need any more info from me 🙂

Just a quick follow up, I completed a short flight from NRT to HKG and I increased the rolling cache to around 128GB. It seem to improve a little bit inside the cockpit but a noticeble drop in FPS was still present with a fair bit of stutters. However, once I landed, I turned off the flight director, and the "LS" button. This helped me recover some more frames. Finally, once I turned off the engines, I was able to recover some more frames but never got back upto the level of frames in cruise or in the beginning of the flight (60fps quite easily)
