Yawn, another thread started because 1 YouTube Expert says something that is gospel.

Everyone will have different performance results based on differing hardware.

I wouldn't waste any time watching the video. Just come here and TELL us what the supposed major change is!

 

 

 

No, this is a video by developers talking technical reasons performance improved.

But you stick with your everything on youtube is garbage and anyone who posts it is spreading garbage animosity...

Everytime someone posts you aren't interested in...

The major change is moving significant parts of the computation that used to be done on the main thread onto separate threads. Sebastian Wloch talked about this in the recent Dev Q&A, and the video at the top of this thread references those statements.

Paul I think this one will be major in Flightsim history and SU4 (despite some bugs) is a huge performance upgrade and finally multi threaded... (the aircraft runs on multiple CPU) as for my system
(9800X3D and 64 GB DDR5) the difference is night and day ymmv...
(I'm not talking about the gains in FPS (I'm at the point I locked the frames at 100 FPS (don't need anymore, go figure) anyways with Ultra) but smooth stutter free :-))
Still with AutoFPS 🙂 Brilliant tool....
As with Flightsim software unfortunately the difference can be huge on the different hardware and systems...
Just sharing my experience and for the first time I'm enthusiast about the performance gains.
So looking forward to the finale release for SU4 with the obvious Asobo breaking something else stuff 🧐
I don't care for those clickbait youtube videos as a system/software engineer I make up my own mind with testing stuff. I think the same holds for you 🙂

Completely agree!  This is right there with P3D going from 32 bit to 64 bit architecture.  

I've also said that all other things being equal something like THIS is exactly why I would move from 2020 to 2024.  Completely eliminate the Main Thread Limitation and MSFS can finally test my 5090!  

I actually said when MSFS was released last year it would probably after the summer before it was where I wanted it to be and it is pretty darn close albeit a few months after I expected.  I would think by 1 yr post release most of us 2020 stragglers will be over to 2024.  Personally I just need ChasePlane to be ready allowing me to copy all my views over and I would probably move right after SU4 drops but we will see.

No argument on anything you said, completely agree.

Couldn't agree more with you Paul indeed the GPU is now far more used 😜

I hope my 5900x get utilized in SU4.  In SU3 it putters around at 30% or less.  Worse in 2020.

You are aware that with nowadays thread shuffling, no CPU usage readout will ever tell you anything relevant? What is your GPU usage? Only this tells you if you are in a CPU limited scenario or not. Illustrated by many feedback that with SU4, the GPU is used more, directly implicating reduced CPU limitation.

I've said it before but this is completely game changing for MSFS24.  I love my 2020 setup and it runs near perfectly delivering almost everything I need but my GPU is forced to run with one hand tied behind its back.  

I've equated it to the significance of when P3D went from 32 to 64 bit.   

Once SU4 drops and it's confirmed all of this made it into the final build I will have to dust off my other M.2 and get serious about 2024...   

Hopefully Chaseplane is there when I arrive LOL 

Still an absolute stutterfest on the ground with me in 2024, even with inferior settings to 2020.  Got to wait until I upgrade my rig..

Even on the latest SU4 Beta?  I am not but it sounds as though people are seeing significant improvements.  

What are your system specs?

Worth to look at, did you check you're installed airports and disabled the double installed ones from Asobo, caught me by surprise after installing SU4 they where enabled again, they where disabled prior to SU4 had to redo those)
In case you're on not on SU4, worth a look anyways

I have a 3090ti and it makes a fine old racket unless I remember to run the rather wonderful Fan Control utility. (https://getfancontrol.com/)

Not just FPS but the video producer's microstutterswere much improved with those frame time numbers...  Very positive and optimistic that this will finally make use of all our HW resources CPU and GPU!!

@Fielder One thing I'll point out though.... look at the difference in this picture which comes directly from that video. Look at the ground textures in SU4 vs SU3. The SU4 textures are blurry and look like complete junk until they load in where as the textures in SU3 look fine all the way in. Runway markings, cracks, they're almost all missing in the SU4 image here compared to SU3.
