Simulation rate 2/4x not possible?

[Arjen Looijenstein]

Hi all,

Just started flying in the A350 for MSFS2020, latesr update. On my way from EHAM tot TNCC and I can't seem to increase the Sim Rate tot 4x. When I try to a short message on the EFB appears with 'simulation rate 2x' and than it disappears again and the Sim is in 1x again. Can do 0,5 though... 

In the EFB is set max compression to 4x. 

Any suggestions on what I do wrong or how I can fix this?

Kind regards,
Arjen

If the plane "detects" something that renders running at more than 1x impossible, e.g. too low FPS, steep turns, unable to hold AP paths etc., it automatically reduces the sim rate again to 1x (or whatever is suitable). 
Mine works flawlessly at 4x, sometimes it reduces it to 2x, but as soon as it is again just straight ahead flight, it switches back to 4x. 

My bet: your rig is not powerful enough to sustain 4x. What hardware do you use?

[Arjen Looijenstein]

Oh, ok. That would be a bummer...
The hardware I use is: 
AMD Ryzen 7 7700X 8-Core Processor
32,0 GB RAM
NVIDIA GeForce RTX 4060 Ti

Ok, with this, you should be perfectly fine to run 4x, at least over the ocean for example. Do you use any simrate tool or do you have assigend a key on the command to increase or decrease sim rate? And even more basic: do you use the automatic sim rate option in the EFB or do you try to increase sim rate manually? I always only use the EFB option in the A350. Only using manual sim rate increase in planes not supporting automatic increase...

That's what I thought as well.

No,. not that I'm aware of. I make use of the Flow Pro panel in stead of the standard menu.
Is just assigned 2 keys for in- and deceasing the sim rate. 
I don't know where the automatic sim rate option is in the EFB... Only see the option in de settings mene (2x/4x). So I try to increase manually.

Ok, then I am pretty sure it is because of this. The plane "thinks" that it should run at 1x because it was not changed via EFB. You find it in the same EFB page where you set max compression to 4x, if I am not mistaken, it is just one or two lines above and you can set it on "auto". The plane then increased the sim rate (if possible) to the amount you specified is max and automatically reduces it accordingly (as described above).

Ok. Thank you very much. I will give it a try.

And thank you again. That helped :-).
