What im actually commenting for is to tell OP that if you are going to try an arena shooter, Q:Champions prolly wont work on a laptop(Kinda making the assumption its not a strong laptop) Xonotic or quakeio have more options anyway. - Source: Reddit / about 1 month ago
If you like Quake-likes, let me recommend Xonotic. It's a free and open source game based on a heavily modified Darkplaces engine. It's a friendly community, with a wide age distribution (lots of old quakers like myself).
