The cards and text are small, but there is a function to check the card and enlarge it for reading (hold left trigger on default).

In every proton setting after 6.3-8 (such as when using experimental, 7.0-6, or 8.0-2) when clicking the in-game menu to start a game (clicking versus) the game screen began to rapidly jitter left/right and continued until restarting the game. I notice it does not bring the port-forward yes/no prompt at all which normally there's a pop-up. The jittering is straining on the eyes and could be slowed by lowering the frame rate, but is still noticeable and annoying. I used proton 6.3-8 and was able to start a game without the jittering starting and the port forward yes/no pop-up occurred like normal.
