Linux

I know im not the only one, trying to get gaming on linux, but im different 😀 I am hooked on Flightgear, (the flight gear group on lemmy seems dead) but im right now playing it (still as a novice) on my Lenovo T470 with Fedora. So well its running okay, but the graphics, especially the suroundings just dosnt look like wheni see thoese vids online about flightgear. So i was wondering, and dreaming about a desktop PC, running linux, that is capable of delevering better graphics in Flightgear.i dont know anything about building a pc, but do you have a recommended setup of all hardware i schould get, and software, to get Flightgear up and running more beautyfull? Im also considdering of using steam as a gameshop. Im such a noob, that i would prefer exsact list of what hardware i schould use. Btw i would like to build my own pc, because im not a fan of thoese gamercomputers with all the colourrd light insight.
