I recently overhauled my entire setup after some suggestions and how popular it is for people in Twitch to have a two PC setup.
I have purchased yet another M2 Ultra Mac Studio to record some gaming videos now, which includes video editing more 8+ hour videos I already do but more gaming ones now. You could certainly do this without an Ultra Mac Studio but the video editing is the reason I went with it. I got an Elgato unit and OBS setup. I have triple displays and have Elgato output to my middle monitor.
This unfortunately doesn’t help the Mac gaming scene, but it makes it less annoying where I’m now treating my Windows PC as a console and still have access to my Mac for research/other things while I game. This also helps my gaming PC as three monitors does have a slight impact to your FPS. Now the PC only has one. Luckily I already had a USB switcher with how many computers I have so I just hit a button to change my keyboard and mouse connection. I was also able to move my PC as far away as I could as it gets too hot while gaming and heats up the room.
This being said PC side needs to focus on heat, I can only use my PC for about 2 hours before my room gets too uncomfortable. I have fans going full blast too. This is the one area where I would like more games on Mac. I already play Minecraft, Tomb Raider, No Mans Sky and Factorio on Mac.
All in all, I’m now happier than ever with my setup. I have also limited my PC use more by now downgrading it to “console” type of system. So I’m not dealing with Windows more than necessary. And I still retain the use of my Mac while gaming and have no impact to gaming performance (watching something while gaming for example).
I know many people can’t afford multiple devices and multiple displays, but if you can this setup is quite nice. Everything is automatic, just change HDMI output from HDMI Switcher, and if I’m on PC change the keyboard and mouse. Literally press three buttons when I want to PC game now (third one is to turn the PC on).
