Doom may be one of the older titles in the gaming world, but it still holds its own when it comes to graphical intensity. Despite its age and relatively small file size, Doom remains a popular choice for benchmarking PC performance. The game demands a solid machine to ensure smooth gameplay, especially during the fast-paced and action-packed campaign battles. While Doom isn’t as large as modern games like Elden Ring, it still offers an intense experience that requires capable hardware.
If you’re curious about Doom’s size and the system requirements needed to run it efficiently, you’re in the right place.
Storage Requirements for Doom
Although Doom is a visually demanding game, installing it on your PC won’t take up a massive amount of space. Its file size is quite manageable compared to many other popular FPS titles. If you’re planning to download Doom, you’ll need 55 GB of available storage. This is significantly smaller than massive games like Call of Duty or Baldur’s Gate 3, which require much larger amounts of space. Despite being an older title, Doom remains relevant, competing with some of the best FPS games on the market in terms of gameplay experience.

System Requirements to Run Doom
To enjoy Doom without performance hiccups, your PC should have essential core components in place. A strong graphics card is crucial, but having a high-performance SSD and a powerful processor is just as important. Doom’s fast-paced gameplay demands a capable CPU to process the rapid movements and intense combat sequences. Veteran Doom players often emphasize that a solid processor is essential to keep up with the game’s action. However, that doesn’t mean you can ignore the GPU—it still needs to be powerful enough to handle the game’s graphics efficiently.
