  • I get how this could be interpreted as offensive, but I think it is just poorly worded.

    This option is for if you are using a legacy version of Linux such as 2.6.x (eg, on an old RedHat distro that your business systems are designed to be run on).

    This enables a compatibility mode so the old kernels don’t complain.




  • Kind of. Think of the RAM allowance as a “maximum” limit, not a reserved allocation. The VM host might have 64 GB RAM, and perhaps allows 20 VMS running in it at once. Each VM can allocate up to a max of 8GB from that host. Not everyone is running their VM at the same time, even if they are, not everyone would be running at their limit of 8GB of memory. If it does happen that 20 users are trying to use 8GB at the same time on one host, then it’s the same as anytime an OS runs low on RAM, it would start paging out to disk, everything would slow down for everyone. If that happens too many times, they could shuffle some users’ VMs around to balance the loads across hosts.


  • Can someone explain to me why it always seems like everyone on lemmy are in one of these two categories:

    1: “I remember my first computer used ferro-magnetic beads that we glued to lengths of string. We could store nearly 10 bytes in one string”.

    2: “My first computer was an old iPad that only had 64GB storage, couldn’t even store my photo album.”

    It’s like everyone is aged either 89 or 19, nobody in between.





  • This particular bug (from the OP) only affects games that use a lot of rapid mouse and keyboard inputs over the period of an hour or two.

    And it only happens (weirdly) when you launch from steam, but have Steam Overlay turned off.

    When launching from Steam, there is a layer that captures all keyboard and mouse inputs before they get to the game (for example, for capturing hotkeys to show the steam overlay). A separate layer called vulkan-steam-overlay (that is responsible for rendering the overlay over the game) periodically clears the input buffer so it doesn’t get too big. If steam overlay is disabled in settings, the input-capture layer is still used, but the vulkan-steam-overlay layer is not used. So the input buffer captures all inputs and never gets cleared, it gets so big it needs to start paging to disk. That is what introduces the lag spikes after an hour or two.

    Launching from Lutris doesn’t use that input-capture layer, so that’s why it’s not affected.
