How far along has gaming on ubuntu come along? Because with those specs, I am more likely to play games on it, than do productivity stuff.
I've been gaming on Linux for about 2 years now and it is unbelievably good and much better than windows in some aspects. Not only games run at high FPS but also you have tools on Linux such as Mangohud that let you change the FPS limit by simply pressing some keys on your keyboard instead of needing to go to GPU control panel or game options.. (for example when you want to BRB you can limit fps to something like 10 to save system energy without the need to exit the game)
Much faster shader complitation on Linux is another strong point of it
thanks to Valve (though it is only for AMD GPUs).. Last of Us 1 for instance needs a huge amount of time to compile the shaders on Windows yet on Linux it does so unbelivably fast..
Another strong point of Linux gaming is that games can run even faster than Windows (for example see
Tom's Hardware report on it). I personally tested Shadow of The Tomb Raider and it ran 30 to 40 FPS faster than windows at main menu alone.
Lastly, Linux kernel can be manually become even more optimized for gaming as Valve recently has
developed a gaming scheduler that can drastically increase system performance for games.
There are some downsides as well: games may not run at day 1 of release (it happened for me on Remnant 2 but it was patched at driver level quickly, but Starfield for example was unplayable for at least 1 month for Nvidia users on Linux...)
Some online games do not support Linux due to Anti-Cheat technologies they use.
VRAM management is not good (but it is recently being addressed)
