From a quick search suggesting somewhat relevant results:

- Using AMD FSR 2 to upscale a 1280x720 render target to 1080p, and all graphic presets set to low they benchmarked ~42 FPS on M1 Pro and 47 FPS on M1 Max.

Around the same ish ballpark as with a GTX 700 series dedicated GPU, released 10 years ago. And around twice the performance of other integrated graphics of other modern CPUs.

At those settings I'm getting about 40 fps. If I bump it up to ultra I get about 32 fps. If I go for retina (2304x1490 upscaled to 3456x2234) I'm down to 25fps, and when I step inside a building I get around 33fps.

The graphics settings to ultra, and retina, you manage 25fps? With FSR perhaps? That's still very impressive if that's the case. I assumed the performance penalty would be severe

Edit: I saw your comment in parent thread.

The game has motion blur, so it doesn't feel too choppy. I'm enjoying it.

There are multiple translation layers in between the game and the GPU. I don’t think this is a fair comparison.

Indeed. I think I only mentioned it because of the original reference to it not being a RTX 4090, with a somewhat adjusted perspective of what performance it is closer to.

I'm getting around 25-30fps at ultra with AMD FSR 2 set to quality. Not great, but perfectly playable for me. In Whisky I enabled "Retina mode", otherwise it runs at 1/4 resolution.
