2020 MacBook Pro twice as fast as RTX 3090 gpu bake

Unity Engine

I’m trying to figure out how this is possible? One thing I did notice is that cudu is usually only used to about 48%. I’ve seen it go up to as high as 58% briefly. I’ve tried updated the windows version to the latest gpu driver and unity 2021.2.16. The Mac is on 2021.2.14. I actually timed it since it seems that the bake time is off on both systems but it’s 5 minutes on the Mac and 10 minutes on the pc. This is the exact same project and seen.

RTX 3090 should easily outperform most discrete GPUs on the market. I don’t know why this is happening. Could you perhaps attach editor logs from both bakes? Perhaps total bake time reporting is off somehow.

I do believe the time is off because they report 40 seconds on the MacBook and 1.5 minutes on the PC but I timed them with a timer on my phone. How do I get the editor log?

Did some more test today after disabling a couple of programs that were starting automatically with the computer. The pc now completes the bake in 3-3.5 minutes. MacBook Pro completes in 4-5 minutes. I’m pretty impressed with my MacBook.
