How demanding is Fallout 4?
Its minimum memory requirement of 8 GB is higher than 37% of the 183 PC games we track. Its 30 GB install is larger than 50% of them.
By today’s standards, Fallout 4 is considered an older budget-class game. The recommended specs suggest a PC that’s several hardware generations behind. Any mid-range gaming rig from recent years should handle it just fine. Plus, its Steam Deck Verified status shows that even handheld devices can run it without issues.
Pay attention to the graphics card, as the recommended specs call for a card with 3GB or 4GB of video memory, while the minimum requires just 2GB. Interestingly, the RAM and storage requirements remain the same across both tiers: you’ll need 8 GB of RAM and 30 GB of available space. For optimal performance, install the game on an SSD if you can. Since it’s a large open world game, having that faster storage makes a big difference.
