A YouTube channel called Mamiyoshi has uploaded a verification video of gaming with the M1 MacBook Pro.
It is a good reference for those who want to play games on their Macbook.
First, we play Fortnite with an external monitor connected.
The screen was quite choppy when playing the game at the highest setting. It seems that the highest setting was too much of a quirky load for the Macbook to handle.
Even when the quality setting was lowered, the screen sometimes froze, making stable play unrealistic.
Next, we tried playing Minecraft and found no problems. Also, there is no fan operation noise at all.
Overall, the system was unstable when playing games that are not compatible with the M1 chip, such as Steam.
Games available on the App Store would work fine.
