P3D V5.2 HF1 VERY HIGH CPU USAGE

[cdv0007 21]

It seems that starting from version 5.2, P3D has become very CPU-intensive, and has reduced its dependence on GPU. Previously, the CPU usage was only about 65%. Now the CPU will continue to work at 100% under cloudy conditions.
I use FSlabs from WFSS product ZSPD——ZSNJ. The reason for consuming CPU may be too many ground buildings or too many volume clouds.
