LOW FPS while gaming
Solution 1:
Ubuntu is not perfect for gaming! Specifically, Ubuntu 21.10 has some improvements but generally, in Ubuntu, you will more likely face lags and crashes while playing games. Here are a few alternatives:
Pop! OS
Pop! OS is more lightweight than Ubuntu and has Vulkan drivers installed by default. Pop!_OS is an Ubuntu-based Linux that provides GNOME as the default desktop. IT offers a polished desktop with its own PPA for third-party applications and app store Pop!_Store to install gaming platforms, such as GameMode, Lutris, and Wine.
The most noteworthy feature is that it allows gamers to install the correct Pop!_OS as it offers separate ISOs for Nvidia and AMD graphic cards. However, in Ubuntu, one can find drivers for Nvidia graphic cards but not for AMD systems. For gamers, Long Term Support (LTS) release will provide better reliability and performance.
Drauger OS
Drauger OS is the most popular gaming Linux distro (as of writing) that’s actively maintained and updated. It has a (relatively) large community of users.
Everything you’d need for gaming on Linux is already installed out of the box, like Steam, Lutris, GameHub, PlayOnLinux. The distro has a rolling kernel and Mesa/Vulkan drivers. The distro uses a different PPA to get more up-to-date NVIDIA drivers, which is a big plus for a gaming distro. Drauger uses Xfce and dark mode is enabled by default.
Manjaro
Manjaro is an open-source arch-based rolling release distribution that offers stability and Arch Linux benefits to beginner users. Manjaro provides extensive support for new kernel addition, upgrade, and management of multiple kernels.
Moreover, Manjaro offers a hardware detection tool that allows quick hardware identification and installation of new drivers. For instance, Nvidia drivers are difficult to work with most distributions, while Manajro provides proprietary drivers for automatic or manual installation.
