Swapspace VS gamemode

Swapfile managed by swapspace plus zswap. Top tier combo

So you can't even google? dev page is here Its already part of the repos for major distros but in fo some reason you had to or wanted to compile it it has cleanly laid out instructions that a child could follow.

To enable Ubuntu to mimic Windows and macOS swap files consider installing the package swapspace, the dynamic swap space manager. It's in the Ubuntu repository.

Windows will increase the size of the swapfile as needed. Linux by default does not do so. If you need that capability have a look at swapspace.

there is a program called SwapSpace that should handle dynamically adding swap files as needed. it's like 2 years old so no telling if it still works.

Install Swapspace (https://github.com/Tookmund/Swapspace), it is a dynamic swap manager for Linux. Essentially, UE5 needs a lot of RAM, sometimes it will try to get more than you can offer. Swapspace will create, manage, and delete swap files to deal with unseen RAM requirements. (You will feel small freezes for a couple of milliseconds when it creates a new swap file, but other than that it will go on in a breeze.) Just run sudo apt install swapspace and you are off.

According to the GitHub page:

A performance optimiser, GameMode by Feral Interactive. It’s not required for anything to launch (unless maybe you’ve configured something to run via gamemoderun and GameMode isn’t actually installed on your system!)

EDIT: Nevermind, fixed it. Just create a file called gamemode.ini in $HOME/.config/, and copy inside this.

Thinking about running "gamemode" https://github.com/FeralInteractive/gamemode.

oh, you're referring to gamemoderun.

The ArchWiki has some tips that can help tuning your system to squeeze more performance: https://wiki.archlinux.org/title/gaming

This launcher does help too: https://github.com/FeralInteractive/gamemode

On top of that, you can use a patched kernel like: https://xanmod.org/

You can check support status for games here: https://www.protondb.com/

If you run games via Proton with DXVK, you can use the environment variable DXVK_HUD=1 to show a HUD with an FPS meter. Some others prefer mangohud.

Setting your CPU frequency scaling governor and GPU to performance mode also helps.

Here's a link, looks like they are indeed working on it: https://github.com/FeralInteractive/gamemode/pull/416

Didn't include your OS but if you are on Ubuntu people reported before missing some 32-bit libraries as seen here https://github.com/FeralInteractive/gamemode/issues/254
