Hello!
Thanks for this guide 
I’ve gotten everything up and running successfully.
The only issue I have is with games that require a mouse interface e.g World of Warcraft.
Once you “click into” the game, the cursor is locked into the game/disappears and I can’t click menu items or anything of the sort.
No issues with controller only games such as Fall Guys, which worked flawlessly.
Any ideas on what could be causing this? I’m stumped
edit:
Upon further testing/troubleshooting, I’ve noticed this issue is related only to Parsec.
If I utilize Rainway, I do not have the issue.
However, when using Rainway, the mouse’s scroll wheel does not work, at all. It won’t function in Windows as a scroll wheel for a window, nor in games like WoW for camera adjustment or Minecraft for your bar selection.
