Will we see Nvidia FrameGen in old games that are engine locked to 30 fps? (self.pcgaming)

There are many games, mostly ported from older consoles, that are constrained to 30 FPS due to engine limitation and if the FPS unlocks, the engine goes bonkers. But what about frame gen? By basically generating additional frame, we could get 60 FPS without triggering the engine jank, since the way I understand it, the framegen completely bypasses the game rendering pipeline and happens only after the frame is rendered by the game.

Yes frame gen could theoretically bring a 30fps locked game up to generated 60fps. But most of these older games won't have the data required by frame gen (per pixel motion vectors), or even if they do have that data it can still be a lot of work for modders to add frame gen support.

AMD has a driver level version of frame generation that doesn't require the game engine to provide motion vectors, but it's much simpler and similar to TVs that have motion interpolation.

Based on FSR implementation and rumours AMD may ditch high end and enthusiast GPU market altogether, I would not put my money on the tech, Best we can hope for is nvidia upgrading the RTX remix to make the implementation even simpler for modders

remember RTX Remix only works for fixed function graphics, so games like Doom 3 with programmable shaders will not work in RTX Remix

Half-Life 2 was mainly programmable shaders, but it had an option for fixed function graphics for older computers, which is how it works in RTX Remix
