Pro 3

Won’t work without gyro. You can fudge the cursor with the mouse but you’ll need a gyro controller for the tilt levels. Not sure how good steam gyro integration is, but my 8bitdo pro3 doesn’t work unless it’s on switch mode and that’s spotty

Same problem here but with the 8BitDo Pro 3. The game just sometimes doesn't detect it. I have to restart my PC for some reason.

I remember an old Pro 2 of mine had the thumbstick cap break in half for doing just that (clicking L3 while steering) - it doesn't help the situation that they don't use the most common size so it's not an easy replacement with any thumbstick found online, it sort of has to be an 8bitdo one... Edit:

I purchased the new 8bitdo pro 3 and seems like a great controller, but I just cannot get the software… I've tried plugging in to my phone, my iPad and my Mac and the software just won't recognize the controller… Is there something I'm doing wrong? I've tried putting in in all three settings.

I think the pro3 will work, I have a pro 2 and it worked with the software. I think yours didn't because you got a wired version with less features. I actually hated using the 8bitdo software, I got tons more mileage out of the $20 red switch/switch2 controller from walmart that let you just hold a
