Not sure if this is the right place … but right now setting the Water Detail to anything higher than “Fair” absolutely tanks the frame rate.
If the current water shader can’t be made performant on Mac’s GPUs perhaps they can create a replacement that’s better suited to the Mac - even if it looks different as long as it looks better than the “Fair” setting.
What are the specs of your Mac?
Im on Mac Studio, M2 Ultra, 64GB purchased 2024 and the water for me looks amazing on High, and I usually keep it at Good for general playing (which looks great too) to keep the strain low.
M4 iMac 10 CPU / 10 GPU cores, aka baseline, 24GiB RAM, purchased end of 2024.
Wish we had a choice of water shader. I rather use an old fashion “static” shader if it means better performance and better looking water at the expense of it being less interactive.
