Native Frame Generation

Nvidia has DLSS 3, AMD has Fluid Motion. Unreal currently has TSR but can we expect some engine-native frame generation technology in the near future? What do you guys think?

We’re getting FSR3 frame gen to UE5 soon.

Personally not excited. I think this will tank optimization even more.

If Nvidia frame gen doesn’t want to work on Unreal viewport, will the AMD frame gen work in viewport ? From the AMD page is not very clear.
I’ve read a page that says the frame generation works even on the older Nvidia cards.
