Project Zomboid: real-USA map mod on Arch, performance?

Hey all,

Planning a new Project Zomboid map run on Arch with one of the newer real-USA map mods. It’s a huge map compared to Knox County, so I wanted to ask here before I spend hours setting it up.

Has anyone tried a map this size on Linux? I’m mostly worried about load times, stutter while the chunks stream in, and RAM usage. I’m also wondering if the default JVM settings are enough or if I should raise the heap in the launch options. Does native or Proton handle heavy mod setups better? And has anyone had save corruption or crashes with a few map mods enabled together?

My setup:

GPU: AMD RX 6700 XT, mesa (amdgpu)
CPU: Ryzen 5 5600X
RAM: 16 GB
Game: Project Zomboid Build 42, Steam, native Linux version
Desktop: KDE Plasma 6 on Wayland
Kernel: linux 6.17, up to date

I’ll post what I find once I’ve tested it. Thanks.

6.17 looks like it's a custom kernel that doesn't come from archlinux , please post the output of uname -a  .

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?
Try clean chroot manager by graysky

Sorry for the confusion, some of the specs in this post were wrong. I’ll test properly and open a new thread with accurate info if I still have questions. Thanks for your time, Lone_Wolf.
