Check your bios settings. If you have an option to set the PCIe Generation to 3 (from 4/Auto) it solves a lot of problems.

Damn, sorry to hear that. Mouse on a different port? When I run your plist through Sanity checker it says you need to add an alcid=layout boot argument, since you are using AppleALC.kext? Maybe look into that (here's a list of layout-codes) I don't use that kext so don't have a lot of advice to give.

Similar problem.

10.14/10.15 RX580 Mouse LAG with 3 monitors.

Hi guys. With 3 monitor when I do Drag'n'Drop, a terrible mouse lag occurs. With 1 monitor lag almost invisible, but exists. Does everyone have this? Ryzen 9 3900X | MSI B450M MORTAR MAX | RX580 | Mojave 10.1.4.6 or Catalina 10.15.4 | OC 0.5.8 | 3 Monitors.

I added it directly to the Device Properties section.
