Fire and smoke artefacts bake and rendering

Hi,

I followed this tutorial : https://www.youtube.com/watch?v=eYol3CTmPgM
But i have artefacts in the bake and in the rendering ( cycle or evee).

Bake resolution division : 100 / 124 and 200 not changing the result
Render (CUDA) : 100 / 150 / 200 not changing the result

GPU : Geforce RTX 2070 ( 8 GB )
CPU : AMD Ryzen 7 2700 ( 8 cores )

I don’t know what i’m doing wrong, here my .blend.

One other thing : Blender is really slow and i can’t move properly in the timeline or the viewport.

I tried on blender 2.90.1, 2.91 and 2.83 LTS

Regards
