Since the disastrous launch of the RTX 50 series, NVIDIA has been unable to escape negative headlines: scalper bots are snatching GPUs away from consumers before official sales even begin, power connectors continue to melt, with no fix in sight, marketing is becoming increasingly deceptive, GPUs are missing processing units when they leave the factory, and the drivers, for which NVIDIA has always been praised, are currently falling apart. And to top it all off, NVIDIA is becoming increasingly insistent that media push a certain narrative when reporting on their hardware.
Yeah, so it doesn’t add latency. It takes like 1-2ms iirc in the pipeline, which like you said is less than/the same/negligibly more than it would take to render at the native resolution.
Which also means it’s not possible to use it to go to 1000 fps
