Almost 8ms on 1080p resolution seems extremely expensive, does the original also eat into the rendering budget as much?

Yes, see the numbers below. In most games, it's basically unusable if you want to play on 60 FPS or above unless you have a 5090.

The current implementation is more of a tech demo than a practical way to play games (+ officially it's available in 1 game). It's _fast enough_ to make some impressive YouTube videos but you most likely won't want to play anything with it yet.

Nvidia has stated that they're still working on improving the performance. No doubt future hardware generations will also include further hardware optimisations.

The potential for this kind of technology is pretty awesome, especially given that people have also found ways to add this to emulators.

Worth remembering it is running a single-step diffusion model working in pixel space to generate each frame, it's a technical feat in itself that people are even using the words "frames per second"

Yes the original is very expensive. It depends on the resolution and the GPU used:

RTX 5060: 9.9 ms at 1080p

RTX 5070: 10.2 ms at 1440p

RTX 5080: 13.7 ms at 2160p

RTX 5090: 8.2 ms at 2160p

The original does tend to reduce the FPS by half or more

probably, going by the reported massive performance hits
