The graphics kinda suck for charting. Except for the recently released Raspberry Pi 4B, which will handle two monitors at 1080p, or one 4k monitor. Also the 4B can be had with 1GB, 2GB, or 4GB onboard RAM. I jsut ordered the 4GB model. Unfortunately EVERYONE is sold out and backordered. But I do intend to see if TWS will run on it or not, when I get it. I will not even bother trying, with a 3B though I have several.
