Doom 4 Multiplayer Will Run at 60 FPS, and Doom 4 Single Player will Run at 30 FPS
Now, let’s all calm down here before everyone gets all noisy and whatnot about this. It’s not really a big deal that Doom 4 will run at a higher framerate in multiplayer. Listen to Carmack explain it to Gamasutra.
“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.”
It’s all about working within the limitations of the machine you’re dealing with. In order to make Doom 4 play better on current consoles and PCs, they lowered the framerate on single-player in order to provide a better experience. I don’t want to hear any bitching about this, you bitches.
