Among the slim and scanty details we have on DOOM 4 so far is the news the single-player campaign will run at 30 frames per second.
“In the Doom 4 project, we decided the multiplayer is 60 frames per second, but the single player is 30 frames per second, so you can have twice as many demons coming at you,” id’s lead engineer John Carmack told Gamasutra while discussing the pros and cons of frame rate and hertz levels.
Although Carmack pushed to have RAGE run at 60 fps, he feels the game’s racing sections require it, while DOOM 4 won’t.
“They’re valid decisions to go each way, and part of it also was because in a driving environment, you notice 60 frames per second a lot more than you do when you’re just walking around. So, that was also part of the deal.”
In the full interview, Carmack goes into greater details on the motivations for the decision, including trading off smoothness for “pretty pixels” and balancing frame rate with greater hertz levels – so maybe go have a read before you start composing your angry retorts.
Carmack also revealed the Doom 4 team includes a dozen programmers, as opposed to RAGE, which had up to 18.
“As soon as Rage ships, the core tech team is going over to help the Doom 4 team,” he added later.
