Upscaling tech (DLSS/FSR/etc) is nice as a way to help older/weaker hardware play newer games, and I’ve really appreciated it on the deck. I really don’t like it when games use it as a crutch to avoid having to optimize their game to an acceptable level.

Frame gen is in a worse spot because it usually only works well on hardware that can already hit 60fps. I’ve never found a built in framegen option that was actually usable on the deck without horrendous input lag and/or graphical issues.

Lossless Scaling’s Frame Gen is a sometimes exception, I’ve found a few Deck games that it works really well with. There are still occasional graphical issues/ghosting with it, but it can help out quite a bit. It’s weird to me that 3rd party software from a small dev would work better than integrated FG from the game devs/GPU makers, but it is what it is.
