Based on a AUR package from Aleksandr i have build a new optimized package for Arch based distributions. Compared to the Beta launcher package use this package the libraries from the distribution so that the size of downloaded and installed files are much smaller. In case i have missed some dependencies please write it in this thread.
Optimized AUR Installer Package
Optimized AUR Source Package
Update: Replaced some double copied libs with symlinks to her original libs. Changed startup script, so that the binary launcher was started from users eve directory and custom logs are stored there (dxvk-logs).
