I honestly believe this is something we have all been wondering, especially myself. FSR 2.0 can be a huge help to getting some very intensive games running and looking GORGEOUS on the Steam Deck. Luckily, AMD, in their blog post announcing FSR 2.1, also showcased the 45 games that either currently or will have FSR 2.0 integration.
The most exciting part for myself was seeing the lineup of games coming out or will have FSR 2.0 support, like the breakout Gamescom star, Lies of P, and a personal favorite of mine that I can't wait to play, The Callisto Protocol:
