Suddenly the speed of RPCS3 get low on Win10

[NewSongZ]

Suddenly the speed got lower and could not beyond 10fps When I was playing the 2nd SRW OG with Vulkan. I tried other games, OMG! All of them run on low speed on RPCS3 with 35% CPU usage!!! What happened??
I couldn't find any trouble in steam games. What's wrong??!!!

Yes!! That's it!! I reinstalled my Windows 10, games playable are ok. But after the fucking Windows update auto, the RPCS3 got sick. Maybe the suspect is KB4034674. I tried the Older RPCS3 version the problem is still there.
Jesus! I thought there was something wrong with hardware.
