Any news on W10 21H1 May update? How does it cooperate with eGPUs? Safe to upgrade from 20H2? Safe to RX 5xxx ?

@susurs, I'm about to give it a go.  Update is downloaded and all I need to do is restart.  This is one of the top google search results so I'll let you know how things go soon after I've had a day or so to use the thing like I normally do.

 PS - I'm new to this site and I did a little cut and paste job with your signature to list my specs.  I looked for some kind of feature in the profile to list my build and didn't see it, so I used your nice looking format.

@susurs, no initial issues after completing the installation of the optional 21h1 update.   I'm running Big Sur on a 2019 MBPro in case my specs aren't showing on my signature and the 2019 version was the last of the Intel  MBP 's.

@jack_bonar, Thank you for sharing your experience with the update and good to hear it’s working fine.

 

P.S. Sure, no problem with copy / pasting the signature at all : )

@susurs, Hey, wanted to give you a heads up that I AM experiencing some issues right now that I do not remember happening before the optional update.  I've read so far that it is a known Windows 10 issue, but for the first time I've noticed that no matter what I seem to be doing while I'm using my MBP, something in the background is continually writing to the hard drive taking up space, to the point that I eventually have to restart and after restarting, the missing space is returned and once again available.  So far this has eaten up as much as 34 GB in one session.   I stream a lot of movies and shows on a wide variety of sites and I play a lot of games on Steam and use apps to idle Steam and farm for trading cards when I'm not playing a game.  I've tried the process of elimination and it doesn't seem to matter where I'm streaming my movies or what I'm doing with Steam and/or Steam Idle or Archi Steam Farm.   I've read that this might be an issue with Windows 10 and the computer using HDD/SSD space when memory is full.   Right now I'm monitoring the issue with a program called TreeSize as well as using Task Manager with all of the optional I/O columns enabled.    As soon as I can be sure that this is NOT an issue from 21H1 I will let you know,  and I plan to report back either way once I discover what is causing this. 

 

Edit:  This is on the details tab in task manager.  All you have to do if you haven't used it before is right click the header tabs below the main tabs and hit select columns, and then you just check off all the I/O boxes.  I've never had a reason to use this feature before and the same goes for TreeSize, although I have found it to be a neat little app that fills a unique niche and I'm glad I learned about it during this whole mess.

@jack_bonar,

Interesting. I updated my Mac Mini to 21H1. I'm not seeing my available disk space disappear.

I just now simultaneously rendered (2) different 3D files in Blender - while playing a couple of YouTube 4K videos. Windows 21H1 didn't do any writing to the Mini's SSD. 

(Installed RAM is 32GB)

I haven't encountered any eGPU issues running the May 21H1 feature update, along with installing AMD driver 21.4.1, and Apple's latest Bootcamp software update.

The resulting Superposition benchmark score remains the same on 20H2/21H1 for my RX 5500 XT - as you would expect with that card.

Windows Blender 2.93 shows some nice Open CL rendering speed up under 21H1 + driver 21.4.1 as the result of AMD's ongoing support for Blender Cycles.

(Side note - Geekbench 5.4.1 Open CL compute scores are broken again under the 21H1 feature update. Just ignore the results)

I could only get my eGPU working because i installed 20H2 looks like recent windows versions are very good for razer core x 2018 mac mini and nvidia 20 series cards.

@mini-i5, it's been several months and I still have a memory leak.   Installing 21H1 is still my primary suspect but I have yet to determine the definite cause, I haven't had the time and plan to run several different tests and try several different fixes this week.   I will still come back to give my solution for the sake of posterity if nothing else.

I suspected the 21H1 update because I installed it soon after I had recreated my Bootcamp installation of Windows.  When I first got my MBP I only put 275 GB in Windows and left the rest for the Mac OS.   But overtime I finally bit the bullet and realized my gaming set up just could not work with 275 so I remade it with 700 of the 1 TB, reinstalled my updates, games, and necessary apps, and then not long after installed 21H1 as an optional update. 

And here's the thing, when my Windows partition was only 275 it was constantly full and I used the same apps and the same games and same streaming sites and so on and if there was a memory leak then I would have noticed it immediately.    But it never happened then.    And now, even if I have a free 50gb, if I play a game or even just watch movie files with VLC, eventually the game crashes or my video playing app crashes and I have to do a hard reset because there is zero HDD space left and therefore no usable memory.   

Off to start some steps and I will report back

@jack_bonar, Wow, what a gigantic pain.

Other members here might have some better suggestions, but the linked article below sounds reasonable.
