To add to that, only a hand full of games were released using the engine Rage, The Evil Within, Wolfenstein: The New Older and Wolfenstein: The Old Blood. Released back during October 2011, the ID Tech 5 engine was supposed to be the next step of ID Software’s game engine and while I won’t get into specifics, the engine wasn’t received well. But what’s the difference you ask? The ID Tech 5 engine was developed in-house by John Carmack when he was still with the “House of DOOM” and was the successor to then ID Tech series of game engine. While Wolfenstein ran on the ID Tech 5 game engine, DOOM 4 is running on a newer ID Tech 6 engine. So what exactly is different between these two games? Don’t they run on the same game engine? However I’ve also seen people compare its performance to several other similar games from Bethesda and company, mainly Wolfenstein: The New Order and its follow-up, Wolfenstein: The Old Blood. However played the game myself as well as beaten it (going for Ultra Nightmare now), I can attest to how well the game runs. Ever since DOOM or DOOM 4 or DOOM 2016, whatever you wanna call it, was released I kept hearing or seeing people talking about how well it runs on their PC.
