Game "pauses" for about half a second every 1.5 seconds like clockwork

Hi Pembroke

I have read through your pain and the one thing that I would try is.

Take your rig to a friends or family members home and use their internet connection especially if its another service provider.

and try across their net connection, I am in the UK and play mmo games for many years we lost a group of German friends for a short period as they all used the same service provider who started making changes and they could not play stable enough to enjoy, when they moved service providers all was well.

You may be looking at your system and its outside of that were the issue lies.

OMG switching one core on and off fixed even the loading time for the galaxy map for me. And I got some more FPS.
We are really not alone: https://www.reddit.com/r/dyinglight/com ... core_cpus/

I/O peripherial wait and inefficient use of the system interconnect can destroy performance, causing seemingly brief "hangs." The early days of transparent memory and load balancing is over, tuning has now reached the desktop gamer.

That's why affinity, both memory and even I/O, is now starting to impact desktops, not just servers (and don't get me started on virtualization). Memory mapped I/O can really be impacted if a different core is handling the I/O from the process that is doing the transfer, especially if they don't share the same caches. E.g., many CPU designs have shared L3/TLB, while they still have their own L1/L2. It's one of the reasons most of us system designers (and I don't mean PC, but board-level) hate the generic PC and generic OSes.**

As always, my top recommendations. Yes, this is generic, but one can Google more for one's PC platform (board/CPU + OS) ...

Turn off HyperThreading (always, absolutely, for any gamer -- hence why get a true quad-core, 4/4 or 4/8 CPU)

Turn off any IRQ balancing or other transparent load balancing for I/O and memory

Set CPU affinity to 0, usually the core that handles I/O, or whatever does

Start disabling cores, so the Turbo modes are on by default -- i.e., turbo speeds usually require cores disabled, and auto-detection is not an exact science

**NOTE: Although Linux kernel auto-affinity is getting better, with its issues too. It's much easier now that systemd is here, because every single service is now contained in its own cgroup. Makes it much easier to tune, or even auto-tune, when every service and thread are in their own cgroups (let alone zombies are no longer possible).
