Hi! I experience kind of input lag. It doesn't make the game unplayable, but really uncomfortable. Doesn't matter what fps limiter I use, it doesn't go away. I play from a laptop with intel & nvidia GPUs, so maybe they both render game and cause this lag (I saw it when running on windows).
How did you guys setup your tablets/game and what the experience is like? Is it perfect?
How to setup GPU drivers on optimus(Intel+Nvidia) laptop:
1) Use only Nvidia and disable Intel GPU. It is probably the easiest to set up. Some distros like Ubuntu and Manjaro(?) even offer a GUI to do that. If you use none of those refer to instructions in arch wiki(will work on all distros, not only arch) https://wiki.archlinux.org/index.php/NVIDIA_Optimus#Use_NVIDIA_graphics_only.
2) Use both Intel and Nvidia GPUs on the same X server (Bitlbee). It probably won't even work, because bitlbee(and bbswitch it uses for power management) are(sadly) abadoned and don't work with newer motherboards. If your laptop was manufactured after 2016 don't even try. If you still want to here is the guide: https://wiki.archlinux.org/index.php/Bumblebee.
3) Use both Intel and Nvidia GPUs on separate X servers (nvidia-xrun). Probably the best solution for modern optimus laptops. Guide is for fedora, but will work for every distro, only installation from repositories differ: https://copr.fedorainfracloud.org/coprs/ekultails/nvidia-xrun/. For usage instructions take a look at its github: https://github.com/Witko/nvidia-xrun
Obviously before trying any of those solutions you need to install propietary nvidia drivers, google it for your distro. If you don't understand something feel free to ask.
Have never had a tablet, but most of players say it is fine, unless you use some no-name chinese tablet. Tablets usually work out of the box, you only need to change area.

Game does not need additional setup after installing drivers, it works just fine. To fix editor menus not being shown launch the game on wine virtual desktop. If audio feels distorted enable/disable legacy audio engine; if mouse does not work properly disable raw input, you don't really need it on linux.
