Respectfully, you have been obviously misinformed. TwisterOS Armbian edition aka Armbian-Reforged is not for gaming only. It's the first out-of-the-box OS solution I've seen for RK3399 SBC's which doesn't required to build/compile/patch code to make it work as intended, that doesn't require to be stuck in legacy 4.4 kernel to have some HW and VPU drivers for it, that doesn't require to be a linux guru with 20 years of experience in the field to be able to use it either. It does come with great goodies too: Panfrost HW acceleration for Linux Desktop, Firefox browser heavily optimized to fully support T-864 Mali GPU, VPU drivers for MPV and Kodi which were built from scratch so can be used on a Linux Desktop to play smooth 1080p h.264 MP4 video files and it works also with mainline kernel. I can keep on, it also boots from uSD, eMMC and NVMe drives, it's visually appealing and behaves like an regular Linux Desktop OS for the general audience, enthusiast user base and specially beginners. It has themes built-in to resemble Mac OS, Windows XP, Windows 7, Ubuntu-desktop, Windows 10. It also comes with several OpenGL games included for (Panfrost OpenGL 2.1 only). It also comes with built-in some useful utilities such as Wine desktop, BOX86, etcher, remmina, Kodi and midnight commander, Kazam, etc, etc
This distribution has been made with the efforts of many so Armbian can reach broader audiences in a clearly attempt to counter the Raspberry Pi syndrome that has taken the ARM SBC world by storm. Peace Out.
Last but not least, moving this topic to a general chit chat section, I'd consider it like a total insult. No offence intended. Maybe we are barking at the wrong tree here. Just my 2 cents.
