Not to poo poo on these mod recommendations, but the majority of theses are meh. If you want high speed action play map wads like scythe, scythe 2, Alien Vendetta, Abscision (newer), Sunlust, DTWID, D2TWID, and many more. Use Cacoawards by year. Mix these with Brutal Doom v21, gzsprfix, Altdhtp, and maybe some sepulcherblack music wad, or idkfa (for Doom 1 map mods, some have original midi sound) and wooo-weee get loose!! To boost speed turn off all post-processing and use vsync with rendering interpolation on.
