Yo! You should make a performance video with GenZDoom :) Since it's based on the open source GZDoom, regular Doom mods are compatible. For instance, I stresstested my M4 512GB 11" ipad Pro with the nuts3.wad map which has over 12000 enemies loaded in. Even with the instakill all monsters command, it didnt crash. 1fps, so the single thread had to work hard for a few minutes. But it didnt crash. 120GB/s RAM and the cpu really did its job.
