Official baseline and practical target
New to the terms? Beginner glossary.
Official minimum specs tell you what can launch the game. They do not tell you what usually feels stable in cities, events, or your first busy session. The real floor is still simple: a fast SSD, enough RAM + pagefile headroom, and enough CPU headroom that cities do not fall apart immediately.
| Tier | CPU | GPU | RAM | Storage | Who it’s for |
|---|---|---|---|---|---|
| Minimum (Official) | Intel i7 (Haswell+) / AMD Excavator+ | DX11.1 GPU, 4 GB VRAM (example: GTX 1060) | 16 GB | 150+ GB SSD required | It runs. Expect stutter in cities + heavy scenes. |
| Recommended (Official) | Intel i7 (Haswell+) / AMD Ryzen 5+ | DX12 GPU, 8 GB VRAM | 32 GB DDR4 | 150+ GB SSD required | Good beginner baseline. Fewer spikes, fewer crashes. |
| Optimal (Rule-of-thumb) | Strong modern 8-core-class CPU | 12–16 GB VRAM for high settings / 1440p+ | 32–64 GB | NVMe SSD + 20% free space | Best “feels good” setup for cities + big events. |

Example PC builds (Rule-of-thumb)
Pick the tier that matches your monitor and comfort target. Stability matters more than a prettier but inconsistent experience.
| Tier | Target | CPU examples | GPU examples | RAM | Notes |
|---|---|---|---|---|---|
| Budget (1080p) | Playable + stable baseline | Ryzen 5 5600 / i5-12400F+ | RTX 3060 12GB / RX 6700 XT | 32 GB | Use upscaling + Low clouds in cities. |
| Balanced (1440p) | Best value “smooth” | Ryzen 5 7600 / i5-13400+ | RTX 4070 / RX 7800 XT | 32–64 GB | Great all-rounder for events and daily play. |
| High-end (1440p/4K) | Best “feels good” | Ryzen 7 7800X3D / Ryzen 7 5800X3D | RTX 4070 Ti Super / RTX 4080 / RX 7900 XT | 64 GB | City consistency improves most from CPU + RAM headroom. |
2-minute diagnosis check
Use this first when you are not sure whether the problem is your PC or just one rough session. If you fail one item here, fix that before you touch ten graphics settings.
| Step | Check (what you need) | What it tells you |
|---|---|---|
| 1 | Game is on SSD/NVMe (not HDD) | SSD is the baseline for streaming. HDD = constant hitching. |
| 2 | Free SSD space: ideally 20% free (minimum: 30+ GB) | Low space worsens caching and can break pagefile headroom. |
| 3 | RAM: 16 GB minimum, 32 GB recommended | 16 GB often relies on pagefile (more stutter/crash risk). |
| 4 | VRAM: 4 GB minimum, 8 GB+ recommended | VRAM overrun causes big FPS drops and hitching. |
| 5 | Baseline test: stable driver, overlays OFF | Removes avoidable variables while you measure the baseline. |
Do this next
- Move Star Citizen to SSD/NVMe if it isn’t already.
- Close overlays for your first test (Discord overlay, GeForce/AMD overlay, capture tools).
- Pagefile: set to Windows-managed (recommended by RSI). If you’re on 16 GB RAM, consider a sensible custom size. (Official pagefile guide)
- Retest in the same spot before/after (same city + same direction) to compare fairly.
If you’re testing during Free Fly
Free Fly servers can be overloaded. Judge your system by stability first, not a perfect city FPS number.
If you plan to buy
Once your baseline is stable, the next step is choosing a starter pack that fits how you want to play.
See starter packsSettings that matter most
The goal is not one flashy FPS number. The goal is steadier frame-times and fewer spikes. Start with the heavy levers, change one thing at a time, and retest in the same spot.
Start with these 3
- Upscaling (DLSS / CIG-TSR) + choose a mode
- Volumetric Clouds (biggest “city killer” for many PCs)
- Shadows (high cost + affects frame pacing)
| Setting | Recommended value | Impact | Trade-off |
|---|---|---|---|
| Graphics Renderer (Official) | Try Vulkan first. If unstable, switch back to DirectX. | High | Vulkan can be driver sensitive. |
| Upscaling Technique (Official) | DLSS (NVIDIA) / otherwise CIG-TSR | High | Lower modes look softer. |
| Upscaling Quality | Quality for 1080p/1440p, Balanced if GPU-bound | High | Balanced/Performance can look blurrier. |
| Volumetric Clouds | Low (or Off if you need a big boost) | High | Sky/atmosphere looks flatter. |
| Shadow Quality | Medium (drop to Low in cities if needed) | High | Less detailed shadows. |
| Textures Quality | High if you have 8–12GB VRAM; Medium if VRAM is tight | Medium | Lower textures can look muddy. |
| Motion Blur / Film Grain / Chromatic Aberration | Off | Low | Purely preference (clarity vs style). |
| V-Sync | Off while troubleshooting | Medium | Possible tearing; V-Sync can add latency. |
| FPS Cap | Cap at 60 / 75 / 90 if you get wild swings | Medium | Lowers peaks, improves consistency. |
Official note on upscaling
RSI graphics settings article RSI recommends DLSS (NVIDIA) or CIG-TSR otherwise.
Safe fixes first for stutter and spikes
Most ugly stutter comes from streaming strain, memory pressure, or something in the background hooking the game. Fix it in this order before you touch everything else.
| Order | Do this | Why it works | Verify |
|---|---|---|---|
| 1 | SSD/NVMe + free space (aim 20% free) | Streaming stutter is the #1 beginner pain point. | Retest the same city run; hitching should reduce. |
| 2 | Pagefile: Windows-managed (Official) | Prevents out-of-memory spikes/crashes when RAM is tight. | Fewer hard freezes + fewer sudden FPS collapses. |
| 3 | Disable overlays while testing (Discord / NVIDIA / AMD) | Overlays hook rendering and can spike frame-time. | Compare frame pacing in the same spot. |
| 4 | Repeat the same city run 2–3 times before judging | Streaming + shader caching can look worse on the first run. | Later runs should feel smoother in the same area. |
Official help: out-of-memory + pagefile
Open RSI pagefile guide If you crash or hard-stutter on 16 GB, pagefile setup is often the fix.
CPU or GPU? Run this 60-second check
Don’t guess. This quick test tells you which settings to change first and which upgrades can wait.
Run this now
- Stand still in a demanding spot (city hub is fine).
- Lower Resolution (or switch Upscaling to a stronger mode) and set Volumetric Clouds to Low.
- If FPS rises ~15%+, you’re likely GPU-bound. If FPS barely changes, you’re likely CPU/streaming-bound.
Likely GPU-bound
- Lowering resolution / stronger upscaling increases FPS a lot.
- Clouds and shadows have a big FPS impact.
- Performance is worse in atmospheres or with lots of effects.
Likely CPU / streaming-bound
- Lowering resolution barely changes FPS.
- Stutter spikes happen while moving/loading assets.
- Cities feel inconsistent even on low settings.
Crash fixes before you try random tweaks
Use this order first. It solves the most common crash causes without turning the page into a full troubleshooting tree.
| Step | Action | Why it helps |
|---|---|---|
| 1 | Verify game files in the launcher | Fixes corrupted/partial downloads and missing assets. |
| 2 | Disable overlays and capture tools | Removes a frequent crash source while troubleshooting. |
| 3 | Remove unstable overclocks / undervolts | Star Citizen can be sensitive to borderline stability. |
| 4 | Update to a stable GPU driver | Eliminates driver-level instability and rendering errors. |
| 5 | Check pagefile settings (Windows-managed is simplest) | Out-of-memory conditions are a common crash trigger, especially on 16 GB. |
Upgrades that matter most
Want the biggest improvement per euro? Fix the baseline first, then spend money on the limit that is still clearly holding you back.
| Upgrade | Impact | When it’s worth it |
|---|---|---|
| SSD / NVMe | High | If the game is on HDD or a slow drive. |
| RAM headroom | High | If you’re on 16 GB, 32 GB is the first upgrade that usually changes the experience the most. Go higher only if you already know you need it for your wider PC setup. |
| CPU headroom | Medium | If lowering resolution barely helps and hubs feel choppy/uneven. |
| GPU | Medium | If you’re clearly GPU-bound and want higher resolution or sharper visuals. |
Next step
Choose a starter pack If your baseline is stable, pick a beginner-friendly starter pack and start playing.
FAQ
What PC specs do I actually need for Star Citizen?
Official minimum is 16 GB RAM + 4 GB VRAM + SSD. For a smooth beginner experience, aim for 32 GB RAM, an 8 GB+ VRAM GPU, and a modern CPU with strong single-thread performance (cities expose weak CPUs fast).
Why does Star Citizen run worse in cities?
Cities are the worst-case mix: heavy streaming + lots of objects + lighting + simulation. If you’re on the edge (16 GB RAM, low SSD space, weak CPU), cities expose it immediately.
Do settings really matter for FPS?
Yes. A few settings do most of the work: Resolution/Upscaling, Volumetric Clouds, and Shadows. Start with the baseline and change one lever at a time.
Is stutter normal on the first session?
Some hitching can happen on a fresh install or after major driver/graphics-setting changes while shaders/assets settle. If it stays bad after 2–3 repeat runs in the same spot, it’s usually SSD/RAM/pagefile headroom or overlays.
Should I cap FPS or use V-Sync?
For troubleshooting: V-Sync OFF first. If you get big FPS swings, add a cap (60/75/90) to stabilize frame-times. Change one variable, then retest in the same location.
What is the single biggest performance upgrade?
Moving the game to a fast SSD/NVMe and going from 16 GB to 32 GB RAM. That often removes the worst streaming stutter and reduces crash risk.
Do I need a high-end PC to enjoy the game?
No — but you do need the right basics: SSD + enough RAM + a decent CPU. If your baseline is stable, you can enjoy most content even if city FPS isn’t perfect.
Should I use Vulkan or DirectX?
Start with the option that is stable on your system. If Vulkan gives crashes or severe stutter, switch back to DirectX and retest in the same location. Stability beats a tiny FPS gain.
How much free disk space do I need on the SSD?
Keep meaningful headroom. As a rule-of-thumb, aim for ~20% free space on the drive that holds the game. Low free space can worsen caching and increase stutter or crashes.
Will more RAM reduce stutter?
Often, yes. 16 GB can work, but it’s easier to hit memory pressure (pagefile spikes, hitching, out-of-memory errors). 32 GB is the most consistent beginner baseline.
Should I reinstall the game if performance is bad?
Only after you’ve done the basics: SSD install, enough free space, pagefile set safely, overlays off, and a stable driver. Reinstalling rarely fixes a hardware bottleneck or memory pressure.
Ready to start?
Once the game feels stable enough, use one beginner-safe path: try Free Fly, judge whether it is worth buying, then choose a starter pack.
