You should be glad you still have a computer. I'm using a Steamdeck handheld console. Yes, this thing can play MFS2020. Normally, when I fly PMDG737, A300, or A346, my average frame rate is stable at 30-28. However, when using the A220 plugin, my highest FPS is when the engine isn't running. I'm flying to AYPY airport, which isn't heavily loaded. On the ground, the FPS is around 20, but it drops to 2 frames after the engine starts. Also, the MCDU has problems. When manually inputting departure and arrival airport information, pressing any key is unreliable, as if it's not adapted for the controller at all. It can't import the route data I need like it does with the A300; it keeps showing "PENDING." Even when I connect the GPU, it still inexplicably shuts down.
