MSFS2024 is causing my GPU fan to screem nost of the time, getting so hot, it is crashing and restarting my PC fairly regularly even when the sim is paused.  I can run 2020 on ultra settings at 60 FPS with a TLOD of 300 whilst I can only run 2024 at medium to high settings with a TLOD of 150.  Furthermore, framerates are up and down like yoyos and stutters (framerates often drop down to single figures) are a constant problem.  What on earth have MS sold us with this terrible application?

Oddly, it seems that performance is a lot worse sometimes compared to other times with the same settings in the same areas (I wonder if this is server related?).

Whilst not current generation, my system is no slouch with a 5800X3D, RTX3080, 2TB NVME and 150MB connection running at 1440 using FRG and AutoFPS (min 50, max 150).

I also keep my system clean and update drivers and software regularly.

How many of you are experiencing similar issues and do MS/ASOBO really have the ability to resolve and stabilise the issues?

 

You may try to set a maximum FPS of ~35 and see if that helps. It did for me. Also lowering your graphic settings can have a positive impact, don't use Ultra settings.

Additional info

If your PC is restarting your PSU is dying. Apart from that, to decrease the heat you have to limit the framerate, since FS24 keeps the GPU at 100% even in the menus (another regression with respect to an issue that in MSFS was fixed years ago...)

Not necessarily. I recently had the same problem, and actually had to reinstall Windows 10 when the restart problem also became a "failed to boot to the desktop" problem. However, I gave my PC a serious clean out (which is something that I had not done in a long time), and now it is running fine again.

1) ups and downs are symptoms of GPU throttling down to keep temps within specs.  sounds like overheating and inadequate cooling.

2) this "terrible" application has run for 4 years with not a single crash and restart of my pc (a lot more powerful than yours). but with good cooling.

the NVidia 3000 GPU series is known for overload power "spikes" which combined with underpowered power supply can easily crash the pc. a 1.000 watt psu and a RTX 4000 GPU can fix that.

 

Igor's lab has identified and described the problem and solutions already back in 2018:

It's possible your GPU cooling fins, along with the CPU cooling fins, have collected a lot of dust. You might open up your computer (with power and other cables outside disconnected) and blow out all of the dust that has accumulated. The dust on the cooling fins can lead to heat build up.

MSFS 2020 runs fine at 60 FPS with hardly a stutter and no cooling issues.  The 'terrible' allplication is the MSFS2024 which should still be in beta testing in my view.

Clean as a whistle and runs 2020 without missing a beat. I have a decent cooler on the CPU which keeps temps below 60C.  The GPU temp is almost permanently around 80C

Framerate is limited to 30 and running at 60 with FRG.  PSU is a Corsair less than 1 year old.  2020 runs absolutely fine using ultra settings

"The 'terrible' allplication is the MSFS2024"

has not crashed my pc once in four years. I suspect some of your hardware is inadequate since our software is the same.

you did read the Igor's lab articles?

2020 is a whole different game (sic). MSFS 2024 makes much more use of GPU programming like no other simulator before (unprecedented 99% GPU load even on the latest RTX 4090).

the age of the PSU is not the issue, but it's rated constant power output (which you did not specify) which combined with an RTX 3000 series has shown to cause problems if below 1.000 W, as mentioned in detail above.

"AMD’s Vega 56/64 graphics card has a very high transient power consumption. The oscilloscope screenshot below shows the transient current when using the two Vega 56 CrossFire for FurMark test, up to 102A / 10ms, which means the power supply must withstand 1200W peak wattage. Even a single Vega 56 graphics card may have nearly 600W of transient power consumption"

"PCGH colleagues recently reported in an article that Seasonic had found unusual load peaks on an AMD RX Vega56 that could lead to the shutdown of a particular type of power supply. The conclusion is that up to 600 watts would be present in a 10ms interval, which would correspond to a current of over 50 amps on the 12V line for a card. The fact that a 550 watt power supply would then switch off after such loads have accumulated would actually only be logical."

Thanks Turbomax.  That is indeed a possibility.  My son, who is an IT specialist and gamer himself told me that a 750W PSU would be more than sufficient when I said I wanted to buy a 1000W one.  Perhaps I need to reconsider this decision.

likewise. just read the Igor's lab article. he has explained the issues of load spikes when those problems arose 6 years ago. or show your son, he might be impressed with Igor lab's test equipment which costs a multitude of my pc.

 

unprecedented 99% GPU load even on the RTX 4090 with MSFS 2024. not because 'terrible' allplication is the MSFS2024" but because of latest, advanced programming, most efficient use of the available hardware incl. the GPU to offload as many instructions as possible from the CPU to the GPU.

this GPU programming was the only way they could increase FPS while at the same time adding much enhanced graphics and non-graphics, non visible features like computational fluid dynamics, particle effects, enhanced ground handling, animated vegetation, soft raytraced cockpit shadows etc. etc.

in-adequate hardware makes this most advanced simulator "terrible"?  😃

like others have said: either reduce your settings or increase your hardware. and you will enjoy the most advanced, most beautiful simulator (yes, they said there will be more bugfixes)

I think you need to up your gaming hardware, I'm running a 2000 series card with no performance issues or overheating.

Not sure my hardware is particularly poor, though not top end.  An RTX3080, 5800X3D, 32 GB RAM and 2 TB NVME drive should really be able to run MSFS2024 better (especially using the autoFPS and FRG mods).

One thing I found out today is that using the MS game bar to check my RAM and VRAM usage is causing a serious hit on performance that does not recover when the game bar (Windows + G) is closed - interested to know if others are experiencing this.

you could also use the windows built-in "task manager/performance" that can show these values as well.

"Not sure my hardware is particularly poor"

nobody said that. it is medium range. it all depends on your game settings and video resolution. MSFS2024 is a lot more complex and can be set to fully exhaust even the latest RTX 4090.  3080 has half the CUDA cores, half the VRAM, 50% lower clock rates than the RTX 4090.
