id Softwaren odotettu Doom Eternal julkaistaan 20. maaliskuuta. Jos alla on oikein kunnon tehomylly, saa pelin halutessaan rullaamaan tuhannen ruudun sekuntivauhdilla. Asian paljasti id Softwaren ohjelmoija Billy Kahn haastattelussaan IGN:lle. Toisin sanoen sujuvuus ja nopeus ovat tärkeitä Doom Eternalissa.
"On id Tech 6, we maxed it out to 250 frames per second. This game, if you have the hardware right, it could hit a 1,000 frames per second. That's the max we have and there's really no upper limit. I've had some hardware here locally that we built just for testing where we had scenes run at 400 frames per second. So people who have 144 Hz monitors or even the new monitors coming out, even above that, going forward this game will hold up for many years"
