RazerGenie VS ffxiv-tools

well there's Razer genie if you happen to run a superior operating system like Arch linux or something...

openrazer: https://openrazer.github.io/ (also has list of supported devices) razergenie: https://github.com/z3ntu/RazerGenie

Also I tried RazerGenie and razerCommander.

If you have multi-button mouse, I recommend Piper or input-remapper. Again, I have had issues using them on Wayland, but they are otherwise pretty good softwares. There is also RazerGenie / RazerCommander if you use their stuff.

For your Razer peripherals there is a project called openrazer. For a graphical way to manage it you could install something like RazerGenie or Polychromatic

Have you read this guide?

ACT - https://github.com/valarnin/ffxiv-tools/tree/lutris-xivlauncher

There's an act installer. Last I knew the overlays were not working as well as cacbot (I really wish cacbot would just die anyway). https://github.com/valarnin/ffxiv-tools/blob/master/Guide.md As for a guide, I'd rather not. You should check out the gshade installer instead. https://github.com/HereInPlainSight/gshade_installer

This is the guide I followed: https://github.com/valarnin/ffxiv-tools/blob/master/Guide.md

Getting ACT to work is tricky, but it can be done. The key is to install it into the same prefix as your FFXIV installation, get the various .NET libraries it needs installed, and run it using the same runtime that you're using for the game. In addition, you will have to use setcap to enable certain capabilities for the wine runtimes, as ACT relies on directly reading network data from other processes and wine is restricted from doing that normally. There's a scripted tool that handles a lot of this, although it's a bit dated so I don't know if it still works -- I used it as a guide to manually perform an installation myself: https://github.com/valarnin/ffxiv-tools/blob/master/Guide.md
