SU12 reduces the graphics performance of the aircraft when the on the ground

Since updating the SU12, whether it is the default Kingair or PMDG, the FPS stability of the aircraft on the ground has a big problem. During the period of taxi and turning, accidental, slight, unpredictable, although the frame rate can be maintained, accidental stuttering will make people very uncomfortable.
I use the old version of the graphics card driver and the latest graphics card driver. The problems still exist. I use 3070Ti and 12700K PC
