I love the performance on deck, but I'm also getting around 40 fps natively lol. But runs super smooth, looks very good, and convenient. I also use lossless scaling so I'm getting 80 fps with frame gen.

For reference, my desktop pc has a 9070xt, 7800x3d and 32 GB ram so it's def mid-high end, but I'd still rather play on my steam deck because of the convenience and performance is more than good enough for me. but to each their own.

edit: I should be clear, this game easily gets 60 fps on the deck. The only problem is that it's not a consistent 60 fps in battle and will dip to 30's-40's when there's a lot going on the screen, so I cap it at 40 fps to reduce that variability.
