MSFS2024 gone from very GPU heavy to very CPU heavy in SU3 beta

We all noticed the outrageous GPU usage when the game first arrived. Well the VRAM bug is mostly fixed but atm, when cruising, the CPU usage has gone up very much which makes for a very stuttery cruise.



I had many VRAM problems in cruise before but now, as you can see in the pictures, the VRAM is chilling at around 6gb 180 TLOD.

The CPU however is struggling. You can see the spikes and every now and then the purple spike of doom.

It varies very much. In the first two pics the CPU is struggling but in the third the performance came back. This happens multiple times throughout the flight and its pretty annoying.

Will this be fixed?

Yes I’m seeing the same thing.

Yep mainthread and rdrthread are getting unreasonably hammered for me too (VR).

What do you mean by “outrageous GPU usage”?

You actually want your GPU to be utilized close to 100% at least if you are not actively limiting your FPS - the GPU running at 100% means it’s running at peak generating as many FPS as it can (another reason to limit FPS to something your display can still show - if your display is 60, 100 or 120Hz you won’t benefit from anything higher. All you do would driving your electric bill).

Maybe I should’ve been more clear. I meant the outrageous VRAM usage. I don’t know what GPU you have but most people don’t have GPU’s with 24gb VRAM. When the VRAM is almost 100% utilized it causes unbearable stutters.

Now, in SU3 beta, it doesn’t use the VRAM as much but you can still see that the GPU is causing low fps and a bit of stuttering.

I’m seeing between 17 and 25% CPU-Load by MSFS 2024 on my CPU, but the main thread is limiting and taking 57 ms to complete during climb in an A330-200 RR flying from the US West coast to the east.
FPS therefore are abysmal 16 to 17 FPS despite MSFS 2024 running on a Ryzen 7 9800X.

I noticed, however, that in LibreHardwareMonitor all CPU-Cores were shown as running at 429 MHz, while Task Manager was claiming the CPU to be clocked at 5.17 GHz.
Temperatures are OK and as soon as MSFS is closed, LHM shows the CPU clocks jumping around like usual (hitting Max-Values of almost 8.5 GHz - Don’t know if those are correct values, but there’s definitely a difference between MSFS running and not running).
Temperatures are okay, so the CPU is not thermal throttling.

Seems to me like there’s some issue with the CPU scheduler, despite the Power Plan being “Max Performance” and all AMD drivers up to date.
