How do I fix the occasional UI lags?

So I installed Success' href='/2020/12/install-macos-catalina-on-supported-pc.html'>Catalina with OpenCore 0.5.9 yesterday and I am noticing a couple of things.

  1. There's this occasional general lag in the UI while typing things for example or while just browsing the web. The UI stutters.

  2. OpenCL and Metal Geekbench scores are low. In Windows, OpenCL score was around 44k whereas, in Success' href='/2020/12/install-macos-catalina-on-supported-pc.html'>Catalina, it's around 32k.

  3. Wired mouse sometimes freezes and wireless keyboard sometimes stops working. Also, PS/2 keyboard isn't recognised even though I did put Ps2KeyboardDxe.efi in the Drivers folder.

Hardware: R5 3600, RX 580, 3000 Mhz Corsair RAM, MX500 SATA SSD.

SMBIOS: iMac Pro 1,1
