Stutter spikes after SU3 - A330

[szymek231992]

Hey,

since SU3 spike stutters have started showing up – they begin right at the takeoff roll. Nothing happens while the aircraft is on the ground starting from cold and dark, but as soon as the takeoff rollout begins, stuttering appears. I’ve already tried:

- redownloading the streamed aircraft

- installing the aircraft on disk

- reinstalling MSFS 2024 (empty community folder)

- deleting WASM

Unfortunately, despite having strong hardware (64 GB RAM, 9800X3D, 4080), even though with FG I get around 120 FPS, right after rotation I start getting strange periodic drops down to around 20 FPS and then back up to normal (they last about a second but happen very frequently).

What could be the cause? It did not happen on SU2. I was describing this issue here: https://forums.flightsimulator.com/t/default-a330-stutters/730484 (screenshot from stutter spike moment - high mainthread load). It is not happening with other aircrafts - strangely it happens with A330 mainly.

Not using any 3rd parties - only beyondatc, navigraph charts. It is also not happening on A350 although it is known for its heavy performance.

The same for me. I followed the instructions but it doesn’t work.
