Wondering how much RAM do open world games need? See real requirements for Cyberpunk 2077, RDR2, Hogwarts Legacy and more, plus a simple 16GB vs 32GB answer
For most open world games, 16GB of RAM is the minimum and 32GB is the best choice. 16GB will run them, but you may get stutters. 32GB keeps big maps running smoothly and leaves room for Discord and Chrome.
How Much RAM Do Open World Games Need?
If you’re asking how much RAM open world games need, here is the short version:
- 8GB: Too low for most new open world games. Some older ones, like Red Dead Redemption 2, technically list it as a minimum.
- 16GB: The safe minimum today.
- 32GB: The sweet spot for smooth play, big maps and multitasking.
- 64GB: Only needed for heavy mods, streaming or video editing.
The rest of this guide explains why, using real numbers from actual games.
Why Open World Games Need More RAM Than Other Games
RAM is your computer’s short-term memory. It holds whatever the game is using right now, so your PC doesn’t have to keep fetching it from the slower SSD.
Open world games are the hungriest kind of game. Here is why:
They load a huge map, not a small level
In a small shooter, you play one tiny map. In an open world game, the PC has to keep buildings, trees, roads and textures ready in every direction, because you could sprint anywhere.
They run lots of characters at once
Busy cities, wildlife, traffic and weather all take memory. This is why open world games often need more RAM than other games.
They keep streaming new data as you move
Ride a horse across the map and the game constantly loads what’s ahead and drops what’s behind. If RAM runs out, this streaming stumbles, and you see stutter and pop-in.
Real RAM Numbers for Popular Open World Games
Most websites just say “16GB or 32GB.” Here are the actual requirements.
Cyberpunk 2077
This game is a good example of why the answer to “how much RAM do open world games need” changes with your graphics settings. The developer lists 12GB as the bare minimum and 16GB as the recommended amount for smooth play. If you turn on the most demanding ray tracing modes, the requirement climbs to somewhere between 20GB and 24GB.
Hogwarts Legacy
On paper, the game asks for 16GB for both the minimum and recommended specs. In real use, though, one testing roundup saw memory usage reach about 21GB to 23GB at 4K resolution. So “recommended” doesn’t always mean “comfortable,” and 32GB gives you a lot more breathing room here.
Red Dead Redemption 2
This one lists 8GB as the minimum and 12GB as the recommended amount. It came out in 2019, so most modern PCs can handle it easily. Even so, 16GB is the safer pick, because Windows and your background apps use memory too.
Assassin’s Creed Shadows
This newer game needs at least 16GB of RAM just to run. That shows a clear trend: recent open world games are starting their requirements at 16GB, so lower amounts are quickly becoming outdated.
16GB vs 32GB for Open World Games
This is the biggest question behind “how much RAM do open world games need.”
When 16GB is enough
- You play at 1080p or 1440p.
- You close Chrome and other apps while gaming.
- You mostly play older open world games or use medium settings.
When 32GB is better
- You play new open world games on High or Ultra settings.
- You play at 4K.
- You keep Discord, a browser and music open.
- You want your PC to stay good for years.
One RAM guide notes that with 16GB you can play big open world games but may get stutters, slowdowns or even freezes while files load. Gaming brands like Kingston now call 32GB the new baseline, while others still call 16GB the sweet spot. Both are partly right. It depends on how you play.
Does More RAM Give You More FPS?
Not usually. Once you have enough RAM, adding more won’t raise your average FPS. What extra RAM does is fix stutter and the sudden drops that happen when you’re low on memory. If your games are choppy while your GPU and CPU look relaxed, RAM may be the problem.
What About Mods?
Modded open world games use far more memory. Big texture packs and graphics mods can push usage sharply higher. If you love modding games like Skyrim or Fallout, aim for 32GB or even 64GB.
RAM Isn’t the Only Thing That Matters
Even after you decide how much RAM open world games need, remember the rest of your PC:
Dual-channel matters
Two sticks of RAM (like 2×16GB) usually perform better than one big stick.
DDR4 or DDR5
Your motherboard decides which one you can use. They are not interchangeable. New builds mostly use DDR5.
Your GPU and SSD count too
A weak graphics card or slow hard drive can cause stutter that looks like a RAM problem. Installing open world games on an SSD helps a lot.
How to Check If You Need More RAM
- Press Ctrl + Shift + Esc to open Task Manager.
- Click Performance, then Memory.
- Play your game, then alt-tab back.
- If memory usage is near 90% to 100%, you need more RAM.
