The ports are better than the PS3/Xbox 360 originals - and very close to the Steam Deck experience.
The good news is that this changed spectacularly last week with the release of Portal: The Companion Collection.
Portal is essentially a series of basic puzzle rooms.
The game has an austere look with repetitive, straightforward artwork.
Areas were genuinely varied and were broken up by extended cinematic gameplay sequences through large environments.
Fine features resolve much more clearly and with more stability.
Dynamic resolution is a possibility but I didn’t notice it during my testing.
Outside of resolution, visual options seem identical between portable and docked play.
Returning to Switch specifically, performance is really where this port goes above and beyond.
It’s not a big deal though and rarely intrudes on the experience.
Portable mode mostly clears up these performance concerns.
Portals run just fine in handheld mode, while the slight stutter during traversal is rarer.
It runs very well indeed - essentially a locked 720p60 in typical play.
The combination of the higher performance target alongside boosted image quality really makes this port special.
It’s a very impressive effort.
For now though, the Portal Companion Collection is a truly excellent Switch port.
This is a superb translation of two great games that shows the Nintendo hybrid at its best.
