How demanding is Marathon?
Its minimum memory requirement of 8 GB is higher than 37% of the 183 PC games we track.
Marathon’s minimum hardware specs suggest an older budget PC, featuring a processor and graphics card from a few years ago. The recommended tier is mid-range, still lagging behind today’s high-end systems. Both tiers run on Windows 10 64-bit and DirectX 12, but the key differences lie in the graphics card and the upgrade from 8 GB to 16 GB of RAM.
The graphics card plays a crucial role, with options ranging from 4 GB to 16 GB. If you’re considering Intel’s Arc cards, make sure to enable ReBAR in the BIOS first. Interestingly, the suggested Ryzen 5 3500 is just shy of the recommended Intel chip, so think of them as similar in performance. The listing doesn’t mention storage requirements, and keep in mind that the Steam Deck isn’t supported. You’ll also need a broadband connection, so keep that in mind when planning.
