Sorry for taking a bit to get back to you. So just tested it, my fans are sitting around 3200-4700 rpm but I forgot to mention its on a well ventilated stand.
dB(A) reading from my phone was about 35 away from my Mac, very quiet, and next to my Mac was reading 45 dB(A). This is according to the NIOSH (National Institute for Occupational Safety and Health) app for iOS. Unsure of how calibrated an iPhone is for dB(A) ratings but thats compared to a baseline.
I tried on my stand plugged to a 4K display with your settings and get similar results. The M2 Max 14 inch MBP needs to be well ventilated to stay quiet.
I found that activating Low Power Mode allows for a 45 to 60FPS in a much more silent fashion on my Mac as, it will cap to a compute usage and not a capacity usage. I'm almost continuously under 3000rpm on my stand, making the Mac fans completely silent.
That's a bit disappointing TBH, but I'm a silence maniac -
FYI: I also tested the game on my wife's M2 MBA, and only managed to get 720p@30 Low settings with TAA and FSR on Quality. That's not very good IMO.
I think we're pretty spoiled by the relative silence of these macbook pros. Try playing BG3 on pretty much any pc laptop, and you'll see. On my desktop with a RTX3080, I actually limit it to 60fps otherwise it'll sound like a jet engine. I have a Fractal Design North case with a beefy AIO also, and it's no slouch in the airflow department. The game just gets heavy, especially in certain areas with lots of NPCs.
Yep, this game has been long in the works with the mac port, so unfortunately they haven't had the chance to use metal 3 and metalFX. Hopefully they will add at least FSR 2.0 in the future, because 1.0 is pretty bad. I also go back and forth between that gaming pc and an m1 max mbp, and the dlss implementation is a lot better. Still, I do use FSR on the mbp, but I turn on antialiasing to smooth things out.
