I Managed to Clean install Catalina and then update to Big Sur. My last standing issue with my install is that when I try and plug in my second monitor, it stays black screen, also my first main monitor (which is a 144hz monitor) Switches to 60hz when I plug in my second monitor. Any help in resolving this issue is much appreciated.
[MONITOR ISSUE SOLVED]
I just switched which port the gpu was plugged into
[System sluggishness and mouse cursor issues]
I found out this is a Big Sur issue with high performance mouses. Just go into the software for the mouse (Razer synapse, Logitech G hub etc) and change your polling rate to 125hz and it should fix it. This will probably be fixed in a later macOS 11 update.
