well doa5 special edition then. also looking at the rate of musou games being released on switch i wouldnt be surprised if koei tecmo will port the dw9 engine down the line.
Dead or Alive 5 (Last Round) DX (Definitive Edition in the west) on Switch is such a super obvious thing. KT's PS3 ports to Switch have been frankly outstanding. DW8 and SW4 both run in 60fps on Switch and I think also run at 900p (Destructoid observes this for DW8).
It's their downports from PS4 that are very hit and miss. WO4 was horrid on Switch, but the Atelier games have gotten better (Atelier Lulua is surprisingly close to PS4 this time, unlike Lydie). Though the Roronoa trilogy seemed iffy, like Rorona DX in the beginning has low-res textures but they get better and become high-res after? Fucking weird from what footage/screens I saw. Totori and Meruru look more identical to the PS4 versions bar shadow quality (I think it's less filterd or lower-res, can't remember, but it wasn't bad like it sounds).
Some field to battle transitions were missing in Rorona and Meruru Switch but for all I know that could've been fixed in any of the four patches the Switch ports received.
