Ya but DOOM and Wolfenstein and Particle effects and light/shadows going off and that seems to be the issue games have on The Switch. Mario Xcom even has its moments where it dips under 30 slightly.
Now I could see them running the games unlocked so it can go up to 60FPS, But I personally don't see a locked 60fps happening. Hope they prove me wrong tho but ether way those games are cool to have on a portable system.
