2023.07.17: add --disable-gpu to fix --enable-low-end-device-mode after last steam update
2023.07.24: add Steam_login shortcut to fix black dialog when auto-login is not used - vgui but disables single-process so +100MB

2023.08.02: rip -vgui and 32bit cef, must use old client for it! this script will help both
