Anyhow: you were right. I just put the gui monitor onto the M2000 and one projector on the 770 instead. Now Spout works.

I have used mac since 91 when I got a mac LC, that is 30 uninterrupted years of use now so its hard to let go. I have some PC's now as well for visual applications. There is no way around it anymore. But I hang on to my trashcan and macbook for every day use. Big sur almost tipped me over the point with all the ios vibes. I only upgraded because the recently released Octane X renderer demands it and maybe it would wake up the eternally slumbering AMD firepro's in the trashcan. (Its not bad, but its a 2013 gpu, so it is what it is)

For studio work, I am trying out Parsec. It is a free screen sharing solution targeted at the game community, who are notoriously latency intolerant.
It took me 2 min to install and now I have the power of my GPU workhorse running in a window on my mac.

So this is how I will deal with it for now. I can stay on my trashcan and have all my GPU intensive stuff crunch away on the PC without leaving the couch. And a bit of windows drudgery actually kind of balances out the noveltyfication of big sur. 

So I think its time to swap out the trashcan for a M1(X) mcMini with Parsec. And maybe after that kick the apple habit completely. At the moment I am trying to figure out which miracle is more likely: apple to be more pro and less iphone again, or windows to reinvent themselves with a soul? What do you think?

Further research about Alienware M15 R3:

This thread implies that the machine does G-Sync: https://www.dell.com/community...

EDIT: it appears to do G-Sync with the specific 144hz screen that offers it. No info about the other screens offered. I've asked and await an answer.

Brilliant!

Jacques, Fred and Bonemap, I have finally determined a workaround for being unable to save the large Isadora patch while editing. It is not related to having media on two different disks, as I thought, it happens when a background video is playing while I attempt a save or during an auto-save. This was an intermittent problem accompanied with one of  two error messages(see attached). If I turn off the movie player and projector associated with the background video, I can save the patch. This is very strange because I have been saving a patch while a video plays to stage since I began using Isadora 12 years ago. This problem occurred on a 2017 Mac Book Pro, 2013 Mac Pro, and 3 different PCs.
