PoE2 steam deck players?

Anyone here is playing PoE2 mainly on the steam deck? I have just started playing. The controls work great, but the graphics do not look great. The default upscale mode "NES" looked atrocious. I changed it to "Intel XeSS" which gives you an "okay" quality. But I guess this can't be helped (or can it?!).

I also played the game on NVIDIA GeForce on the deck, and the graphics is much better with consistent 60 FPS there as you'd expect. How's the experience so far if you're playing this on the deck?
