I’ve thought about throwing more ram at the problem, but until we get more 3rd party planes into 24 I am holding off. 

Probably a good idea. Although it seems that 2024 will swallow a lot of RAM, and that the sim *might* be smoother with RAM over 32GB, the sim is far from mature. 

I'll do some more performance tests later today and try to troubleshoot the frequent stutters that occur despite having very good FPS. I'll run most things default with as few addons as possible. I'll probably keep the Fenix though. I think. Hmmm. 

On second thought, just in case the stutters are related to the Fenix A32X (which after all are in an experimental stage), I should probably go for one of the default airliners.

I admit to a personality flaw that will continue to see me attempt to work in FS24, but yeah, waiting for all my planes to come over and then move to 24 is a better idea.

If you really feel up to it, running the ini A320 in each sim but have value. But, I think the Fenix is actually a good test sample.

With my system (Ryzen 5800X3d, RTX 4080 Super, 32 Gigs RAM, 4K monitor), I find the FPS quite acceptable, usually holding at 75 - 80 FPS with DLSS and native FG on. But with complex 3rd party aircraft (Fenix, C414) near complex airports, the momentary stutters are prominent. While monitoring memory, I find RAM usage at about 23 Gigs of 32 available.  GPU usage maxes out at 98 or 99%.  Hopefully, with updates to the sim and addons, the stuttering will be addressed.

With GA airplanes and the default liners I'm getting better fps than FS20, but with Fenix the problem is the RAM leak, close to 90% of 32GB, and the stutters at the airports and landings.

I will not deny that I have a similar flaw 🙂 I'll do a 2020 vs 2024 comparison with no addons. Just need to find a suitable aircraft. Isn't the ini Neo in both sims?

Yeah it is. I don't know how much has changed between sims. But it's as good a control sample as any.

Also, I don't have any sort of benchmarking tools but I am tempted to just go with 24-only for a week and document (at least for me) how it went. That complete lack of headroom I have is a blocker to that. I am curious if the sim just grabs as much as it can to try and reduce issues later on.

Performance for me is similar, and I don’t even have many of the addons installed yet, frame times are better however.

Allright here we go... drumrolll... MSFS2024 vs MSFS2020 performance comparison!

Situation: iniBuilds A320 Neo flying at 3000ft and 250kts from EGLL to EGLC. 

Settings: 4K DLSS+DLAA, FG on, TLOD 100, OLOD 200, ultra settings. Empty community folder. 

MSFS2024:

MSFS2020:

Summary: 

• Average FPS 28% better in MSFS2020
• 1% low average 42% better in MSFS2020
• 0.1% low average 102% better in MSFS2020
• Average CPU load 18% in MSFS2024 vs 15% in MSFS2020
• Average sim RAM use 15GB in MSFS2024 vs 8GB in MSFS2020
• Average GPU load is about the same
• I didn't include the average VRAM use - sorry!

I guess the numbers speak for themselves. I must have been deluded thinking that performance is much better in 2024 as it handles situations with FSHud better (higher FPS, can load more traffic). Overall, performance in 2024 without any addons seems significantly worse than 2020. 

Note: the Y-axis is not the same in the two graphs, as 2024 had much higher frame time spikes - which is not a good thing. Also - even though FTV <2ms is a bit better in 2024, the subjective experience was much worse as the stutters were much more severe - which correlates well with higher frame time spikes and lower 1% and 0.1% low average.

Thanks for taking one for the team on this one. Fantastic methodology.

Yep...
Some say 2024 is better but many times with almost vanilla 2024 compared to full loaded 2020

Thanks Captain Piett for this comparison. We now have objective findings based on data not subjective impressions. Safe to say that 2024 needs some work before it will be the equal or better to 2020 for performance. 

Was this done with X3D Game Mode enabled in the BIOS?

As of the last patch way better performance in 2024, better than I ever saw in 2020.  I hope it keeps up.

You see, that's the strange thing. After the 1.2.7.0 and 1.2.8.0 i have really bad stutters in the fenix at heathrow that weren't there before.

I run ultra settings with native FG on a 4090, 12700K hyperthreading on @ 4.8GHz and 64GB DDR 3600 RAM with an XMP profile.

The sim itself recommends ultra settings for my hardware but although I can maintain 60FPS the stutters are crippling, like stop, start big stutters. Impossible to control an aircraft type stutters.

Anyone with similar hardware to mine who own the Fenix, try spawning into EGLL 09R and just taxi around, I'd love to know your results.

It doesn't matter whether I have low settings or ultra, the stutters are ever present.

I have cleared all cache and use the hotfix driver 566.45.

Have to say I'm really disappointed at the moment with it.

Just tried that on my MSI board (which just disables SMT, if anyone's curious) and tried it at EGLL 09R, just to test if what Bunchy was saying was present on my machine. Toggling game mode on dropped FPS by about 10-15FPS and significantly increased stutters, like to a point where I'd call it unusuable. Toggling it back off, it's smooth but still not maintaining a perfect 90FPS (FG) at EGLL and occasional stutter when looking around quick but taxiing and general usage is very smooth. So at least on a 9800X3D, I wouldn't suggest enabling Game Mode.
