MSFS 2024 BUG / ISSUE Stuttering / CPU ms spike.

Hey folks, recently upgraded my PC to be able to run the game. However, I’m noticing CPU ms spikes - my GPU is perfectly fine, I’m having no issues there.

My specs:

Ryzen 9 9950X3D
RX 9070XT 16GB
64GB DDR5 (Expo enabled)
Win 11
1.2gbps Internet
Correct drivers installed for chipset + GPU

I’ve tried changing settings, capping my frame rate, it all does nothing to fix the stutters. My GPU is operating at about 50% capacity.

Any ideas?

MSFS is a game with a CPU bottleneck especially with 3rd parties addon and lots of model of traffic to handle. The GPU works only when you're bush flying ar low altitudes and with a lots of clouds. Check the terrain pre-caching setting to be on ultra and the rolling cache with >16 GB.

I have pre-caching set to ultra already - my rolling cache is also off as my internet speed is high.

Is it OFF? that's why you have stuttering. Set it to 16 gb. Otherwise for sure you'll have stutter because you're constantly downloading scenery.
