Should I update to Big Sur?
@marko_mitranic, boot camp? Which windows version?
A) 2020 MacBook Pro, i7-1068NG7, 32GB RAM, 1TB, EGPU Razer Core X, Nitro+ RX5700 xt 8Gb, Samsung 49 1440p UltraWide C49RG
Mac OS Catalina 10.15.7, Internal Bootcamp Windows 10 2004 pci.sys swap.
B) 2.7 GHz I7 4 Cores, 16Gb, 1TB MBP 13 2018 TB3 , EGPU Razer Core X, Nitro+ RX5700 xt 8Gb, LG 32UK550
Mac OS Catalina 10.15.2, Ext SSD Windows 10 1903 V1 .295
Bootcamp only works (for me) using the 1903 v1 build stated on this site. No other procedures worked for me.
Ok with Big Sur I ran into some trouble with a game or two on Steam using the eGPU on macOS. Corrupt screen on XCOM 2 for example. Everything else is running so buttery smooth and well worth it. I noticed the screen is more solid and does not appear to be using temporal dithering any more as of Big Sur. My external 4K monitor is noticeably sharper and colors seem more restricted to the native palette of the monitor vs interlacing. Big win for me. I prefer clarity vs interlacing colors as I can see them.
Setup prior to upgrade:
MBP 15" + eGPu + LG 32UL950 via Display Port.
I didn't have boot graphics, so always had to boot with the laptop open and then the external monitor would come up. No news here. Just a bit inconvenient.
Everything else worked fine.
After the Big Sur update I noticed that the monitor wouldn't shut off (Energy settings on my Mac sets the monitor to "sleep" after 10 minutes idling) but thought nothing of it.
Then a few days later I got a new Mac mini (Intel).
Had some issues during the Big Sur upgrade (screen wouldn't come on after mid-upgrade restart). Connected the monitor to the mini directly via HDMI and upgraded.
Now it is all ok. Computer boots up correctly with the monitor connected to the eGPU via Display Port.
The only issue I have is: on the Mac mini too, the monitor won't "sleep".
If I manually set the computer to sleep, it all works ok.
Not sure if it is an eGPU issue or not...
In my experience Big Sur breaks 16" MBP eGPU support in bootcamp above 1903. I had it running on 2004 for a while, but installing Big Sur has broken support. I haven't gotten it running on 1903 yet, but other 16" MBP users have said reverting to 1903 fixed issues (and shared my experience of failures above 1903 after updating to to Big Sur).
For me - it's been great.
I upgraded from Catalina 10.15.6 directly to Big Sur 11.1.
I ran the installer from software update. It took less time than the Catalina updates.
I re-set my Mac Mini's PRAM/NVRAM after the installer finished, holding down Command+Option+P+R at startup.
Big Sur performance is noticeably better all around on my 2018 Mini.
Accessing files on a remote file server is way faster using SonicWall Mobile Connect VPN client than it was before on Catalina. That alone is reason enough to upgrade.
Maya 3D and AutoCAD run better on Big Sur as well.
Good times. 😎
