AMD details its Nvidia DLSS 3 Frame Generation-fighting tech

pcgamer.com:

For once we were right(opens in new tab). AMD has indeed revealed the first details of its upcoming answer to Nvidia's DLSS 3 Frame Generation technology(opens in new tab). Known as frame interpolation, the technology will arrive with AMD's FSR 3 upscaling platform. AMD hasn't put a date on the release of FSR 3 or frame interpolation beyond a classically vague «later in 2023».

The details came in a presentation made for GDC or the Game Developer Conference(opens in new tab). AMD says frame interpolation can increase frame rates by as much as two times.

As with Nvidia's Frame Generation, the idea is to generate whole new frames in between fully 3D rendered frames to increase the overall frame rate and therefore perceived rendering smoothness.

AMD's slide deck for the event shows how frame interpolation fits into the rendering pipeline, dramatically increasing the overall frame rate. But it also demonstrates how it introduces latency.

AMD's answer to that problem is combining frame interpolation with upscaling. Long story short, upscaling reduces the latency over native rendering much more than the increase in latency due to frame interpolation.

So, combining upscaling with frame interpolation delivers both much better frame rates and much lower latency than native rendering. It's not clear whether AMD will enable frame interpolation to run separately from upscaling, as Nvidia does with Frame Generation in DLSS 3.

But the slide deck seems to imply that frame interpolation is something intended to run with upscaling rather than as a stand alone technology. «FSR 3 combines resolution upscaling with frame interpolation,» the slide deck explicitly says.

AMD emphasises that latency reduction is a focus area for FSR 3,
