I was experiencing frequent crashes like others have reported here. I headed into properties and changed compatability to Proton Experimental then went to general and changed game resolution to 1280 x 800. Have now played for an hour and a half crash free. Runs perfectly now.
It just works.

Occasional crashes while playing Metal Gear 2 make things frustrating meaning chunks of the game need to be played over if it's been a while since saving

Manuals would display errors

Después de hacer Alt+TAB y volver al juego, se queda en modo ventana
El juego necesita el comando para limitar los FPS a 60 o sino va demasiado deprisa. Al hacer Alt+TAB y volver, el juego se queda en modo ventana y no puedes ganar el control de nuevo hasta que pulses el botón START del mando de Xbox.

DXVK_FRAME_RATE=60 %command%
After alt+tabbing, cannot fullscreen or interact with game window.
Game runs too fast if framerate is uncapped. Limit framerate to 60 FPS by adding DXVK_FRAME_RATE=60 %command% to launch options.

10-20 seconds between going fullscreen and windowed.
For the record, this is the MSX version.
