NVIDIA's purported GeForce RTX 3090 (or RTX 3080 Ti) is reportedly 50% faster than the GeForce RTX 2080 Ti in TimeSpy Extreme.

3090 is the super expensive one though i think, curious how a 3070 will fare against a 2080ti
i think i read that DLSS 3.0 may only work with 3xxx cards and it can provide a 50% FPS boost while also delivering better visuals, DLSS 2.0 already does pretty good on a 2060
(DLSS basically uses nvidia cloud servers to pre-compute highly optimized render paths for specific games and scenes so games can shortcut a lot of work while rendering)
