CemU Outpaces Nintendo, Runs Mario Kart 8 In 8k

The latest CemU update has smooth 8k, 60fps gameplay that even looks impressive sampled down.


Despite our qualms with the CemU Wii U emulator, the efforts to bring a perfect version of the latest Zelda entry to PC were honorable and quite successful. The 1.8.1b update had Breath of the Wild running in 4k from open to close and now, as reported by Kotaku, CemU has upped the ante by having Mario Kart running in 8k after it barely ran at all in an earlier version of the emulator.

Will, who uploaded the clip, is running CemU on a PC equipped with i7 6700k and a GTX 1080 Ti. He hasn’t uploaded the raw 8k footage yet and there’s no guarantee he will considering how few would be able to actually run it in all its glory, but the version he put on YouTube is a supersampled 4k clip that is still quite impressive if you don’t have the right screen to view it. The clip is of gameplay footage made while playing in 8k, and that’s the key. It’s incredibly smooth and has come a long way since roughly running the game in 2015.

This a technical feat for sure but will CemU be able to keep pace as Nintendo undoubtedly tries to find a way to shut the emulator down?

      Requiring nearly 0 CPU power and being designed to be able to run at 30fps will do that, apparently.

        Mario Kart 8 runs at 60fps though

          In single and two player, yes, it was built to also be able to run at 30fps. Didn't see that it was at 60fps at 8k the first time through the article so I made an assumption. Quite impressive regardless.

      Eh, Nintendo hasn't gone after emulators in a while; Dolphin's development is pretty public and gets similar show off videos from time to time.

      As long as they don't touch the Switch and don't start doing stupid stuff like distributing or linking to games directly I doubt they'll get any friction.

          I doubt these emulator scenes, even at their most accessible, will ever come close to making a dent in Nintendo's margins. It's simply too niche of a scene. And even if it's 4k, 60FPS on PC, you don't have the killer Switch gimmick of portability. Don't think they have anything to worry about.

            I mean, everything else being close I'll prioritize buying the same game on Switch over PC. The portable hybrid nature of the system is a competitive moat that nothing else has.

              If Switch carts continue to be available, I would still go that route, even if I planned on playing via whatver switch emulator comes to prominence. I'm still a sucker for physical media. Please god someone take these CDs and records and blurays off my hands.

              And the Switch version doesn't have that dropped-frame "hitch" once every 1 or 2 seconds. From the video I can see it is still present on Cemu

        The difference with Cemu is it's closed source and potentially based on leaked SDK info rather than reverse engineering. The latter is legal, the former not so much.

          I haven't followed Cemu at all - is there reason to think that other than it just being closed source?

            They’re making insanely fast progress compared to most 3D console emulators, so they almost have to be using some kinda shortcut to working all that shit out.

      Went through that video with MY NEW 4K SCREEN and it looked very impressive. Had some more polygons been thrown into the character models, it would look like movie CG. The CemU guys are doing impressive work.
