Diablo Iv Offline Mode -

The Steam Deck can run Diablo IV at 60fps on Medium settings. It looks incredible on a train or an airplane. Unfortunately, trains go through tunnels (no signal), and airplanes have "Wi-Fi" that costs $30 for 15mbps of lag. The hardware is capable of offline play; the software is not.

You can start a Rogue on your PC at lunch, then pick up that exact same character on your PlayStation 5 on your couch, then switch to your Steam Deck in bed. This is a technical marvel, but it relies entirely on Blizzard’s cloud servers holding the "source of truth" for your inventory. An offline save file would immediately desync from that cloud truth.
