There are some early previews where people ran some actual games at it[0].
Here are some of their results:
> In Cyberpunk 2077, running at 4K, it’s a surprisingly stable 60fps, albeit with the caveat of that using FSR 3 upscaling on Performance mode with Medium quality settings. But, also: basic ray tracing, something the Deck can’t even think about enabling outside of very specific games.
> The next game I tested, Black Myth: Wukong, is best run with its own RT effects switched off. Still, it also averaged around 60fps on otherwise similar settings: Performance-level FSR 3 upscaling to 4K, plus the Medium quality preset. And, in an almost unnerving repeat performance, Silent Hill f ran close enough to a solid 60fps (with most drops owed to Unreal Engine 5’s signature stuttering) on the Performance-level graphics settings and, once again, FSR 3 running on Performance mode.
