No mention of resolution, but nice nonetheless.
Or use of frame gen.
Yeah could be.
Given the point of this tweet is put put the Mac version of the game over and the specifics aren't mentioned, I'd guess this is at 1080p, no RT with MetalFX image reconstruction and framegen. If framegen is similar to the DLSS before MFG came along it's likely a ~50% uplift, meaning ~80 fps with framegen off. I'm presuming that the image quality is decent, if they're showing this to the press so it's likely at least a 540p internal render (i.e. balanced) and hopefully a 720p render (quality). If so, this could suggest a playable frame rate with RT enabled, but we'll have to see how well path tracing/ray reconstruction works.
Not looking forward to seeing the performance on base level M chips though...
