P3DV5.3 vs P3Dv5.4 what is the difference?

[B38058]

I've read some posts that V5.4 has some xml coding issues 

https://www.fsdeveloper.com/forum/threads/xmltools64-c-simvars-problem-in-p3dv5-4.457499/

What would have to be done if one wanted to revert from 5.4  to 5.3?

I found this video interesting.

I use v5.4 with no problems whatsoever. My question would be why bother reverting backwards? Adam is a solid guy that puts in tons of free time to help the community on his discord but I don't use a lot of his tweaks and don't bother reading too much into many of the videos even if all he is trying to do is help....If it ain't broke....???

I'm a new p3d user starting with fresh install of 5.4 no previous p3d on pc only fsx and msfs. It has stunned me with stability so far. Only one ctd on first flight 60 fps ultra settings mostly. Only poorly coded airports like ybbn orbx slow it down to 30. I haven't used the other sims since I seem to have picked the right version to start with.

use the lossless scaling app you can get on steam and you will be able to use everything and get 60fps....obviously you have to play with settings a bit but either way you will be impressed.

 

as example, I am currently flying into new york area (KLGA to be exact) and am getting 60 fps with full AI aircraft and KJFK and KEWR addons enabled....never could get even 20 before....

Uninstall the 5.4 client only, and then install the 5.3 client. However, the last time I did so I got a stutterfest. I cured it by returning to v5.4.

I have read up on that app. Don't need it yet as I get 60 locked except for one addon but if I squeeze more ai out of sim I might do so! 

Still testing default right now before I make changes

ahhh default....well, the more you add for eye candy (ie true earth etc) the more the fps will drop...not sure what regions you typically fly in and out of but if you are located in London, you will be able to use either UK2000 EGLL or Simwings version full ai with no trouble...without lossless scaling...not a chance.

What is that logo all about? Cheap fllights? 50% off?

For me v5.4 was a real pain. Random freezes around the planet that only started with v5.4.

I suspect it was some AIG BGL files as the problem disappeared once Ai was set to zero.

Looking at the changes in v5.4 many changes were made to flight plans. Impossible to find the files responsible. Easier to revert to v5.3HF2 which has remained rock solid.

I'm actually running the entire OrbX catalog for P3d/FSX and 2 PMDG planes/Q400 right now.

So default-ish :D

That's my virtual airline SLOPAIR. See below for our resident captains cavalier attitude to passenger safety!

There were 3 factors that made me decide not to update to v5.4 from v5.3 HF2. They were:-

 

a) someone reported black textures using FlyTampa's EHAM scenery and I never did see any follow up or resolution to this

b) the Job Scheduler functions were locked down more in v5.4

c) the v5.4 update didnt really offer anything substantially new for me.

If I can plug for 5.4 the greatest improvement for me (and it’s a big one) is the elevation fix in several addon airports such as FSDT KMEM. In previous versions of V5 the aircraft wheels would float about two inches above the pavement in a few FSDT airports.

I can corroborate that! I noticed the same issue in that same airport. When I saw that the wheels were now touching the ground, I wondered if FSDT fixed it or P3DV5.4 🙂

Isn't it the opposite in 5.4, you have more control over core assignments for the three main threads? With previous versions, you have the process affinity mask and that's it.

No, I dont think so Luke. I have a Job Scheduler that can assign the P3D main thread, the terrain (Renderthreadscheduler) threads and Frameworkerthreadscheduler to different cores in P3Dv5.3.

If i am not mistaken, in v5.3 you could assign the P3D main thread to any core (whatever is your fastest core for your CPU) but in P3Dv5.4 I thought it was locked to core 0 (so I read), but I stand to be corrected as I never did install v5.4

If that's not the case, that would be one less obstacle in moving to v5.4.
