Is frame generation fake fps?

The frames are real images on screen, but they're AI guesses rather than frames the game rendered, and they don't respond to your input. Motion looks smoother; responsiveness doesn't improve.

Does DLSS add input lag?

Upscaling lowers the rendering work to raise fps. Frame generation adds input latency, because it has to wait for the next real frame before filling the gap.

What is the difference between DLSS and XeSS?

Both are AI upscaling and frame generation technologies: DLSS is Nvidia's, XeSS is Intel's. Which one a game offers depends on the game and your graphics hardware.

What is frame generation, and are those frames real?

SHORT ANSWER

Upscaling (like Nvidia's DLSS or Intel's XeSS) renders a game at a lower resolution and uses AI to fill in a sharper image. Frame generation goes further: AI invents extra frames between the ones the game really draws, so the fps counter jumps. It looks smoother, but generated frames don't respond to your input and add some lag, so "92 fps with frame generation" isn't the same as 92 real frames.

EXPLAIN IT LIKE I'M 5

Frame generation is like a flipbook where a helper draws extra pages between yours. The animation looks smoother, but the helper is guessing — and you have to wait for your next page before they can draw the one in between.

How frame generation fills the gap

Real frame ARendered by the game
Real frame BRendered, then held back briefly
AI frame in betweenGuessed from A and B
You see A → AI → BHigher fps, a little more lag

Smoother motion, but only the real frames respond to your controls.

Upscaling

Nvidia's DLSS and Intel's XeSS let the graphics card render most of each frame at a lower resolution, then use a trained AI model to produce a higher-resolution image that approximates full detail. The result is more frames per second or higher settings for the same hardware. It's now common enough that consoles like the Nintendo Switch 2 rely on DLSS.

Frame generation

Frame generation creates new frames by interpolating between two frames the game actually rendered. Newer "multi" frame generation invents several frames for each real one. Because the game must render the next real frame before it can fill the gap, frame generation adds input latency, and the guessed frames can show visual artifacts.

Reading fps claims

When a chip or console is advertised with a big fps number, check whether upscaling or frame generation was switched on, and compare native performance too. Frame generation makes motion look smoother, but because it adds latency it can't make a game respond faster.
