Foldit is memory-intensive. I get that. Puzzle 1948 is larger than most. I get that, too. But I have never seen a puzzle use more than about 300 MB of memory.

Puzzle 1948 is currently using over a GB in memory, which explains why I can't stop the current mutate script from running and why I can't even minimize the window in which it operates.

Is anyone else seeing this? Is this just my machine, or is there a more serious issue?

Hmm, that is a bit surprising... Is this soon after you start Foldit and load the puzzle? Or is this a client that has been running for a few hours already? Have you switched puzzles since starting Foldit, or did you go straight into Puzzle 1948?

You might also double check your settings in the Undo Menu -> Graph Properties. By default the Max Graph Length is set to 25; increasing this value will definitely increase the memory usage of your client. We did have a recent bug where this setting failed to save when closing the client. That bug is fixed now, but if you played with the Max Graph Length setting in the last few months, your changes might not have been saved.

When I checked, it was after hours of running. I was only running one client, and only puzzle 1948. My graph length has always been set to 25 steps.

Memory usage seems to increase with the number of residues in the protein. My design for 1948 has 287 residues. This is the largest puzzle I've seen since I returned to the game last April.

Chats with other players who use different operating systems and versions reported the same high memory usage.

Hi Boots!

I'm curious if you can compare your memory usage between 1948 to the new ED puzzle: 1952.

Thanks!

I'm currently running a rebuild script on 1952, and it looks like it's consuming about 945 MB of memory.

Thank you Boots, that is a helpful reference.

As an FYI, 1952 with no scripts running uses 808 KB of memory.

Thanks!
How does that compare with 1948 without scripts?

I pulled 1948 out of the archive. Using 590 MB doing nothing but sitting there.

Sorry... 808 MB of memory. 808,000 KB.

1952 uses 808 MB of memory.
