Star Citizen System Requirements (2026) — Can Your PC Run It?

TL;DR: At minimum you need a 64-bit quad-core CPU (Intel i7 Haswell or AMD Ryzen 5 equivalent), 16 GB RAM, a GPU with at least 4 GB VRAM (GTX 1060 / RX 580 range), and a Windows 10/11 64-bit install. Minimum specs will technically get you into the game, but expect 20–30 FPS in cities and long load times. For a genuinely smooth experience in 2026, you want 32 GB RAM, an RTX 3070 or RX 6700 XT or better, and an NVMe SSD. Star Citizen is one of the most demanding PC games available — it taxes CPU and RAM harder than almost anything else.

Updated 2026-05-15. Star Citizen is in active Alpha development — specs are subject to change with major patches. Always check the RSI support article for the latest official requirements.

Official Minimum Requirements

These are the specs officially listed by Cloud Imperium Games. Meeting these gets you into the game — but the experience at minimum settings is rough, especially in populated areas.

Important CPU note: Your CPU must support AVX, AVX2, and FMA3 instruction sets. Most Intel CPUs from 4th generation (Haswell, 2013) onward support these. If your CPU predates Haswell or is a very old AMD chip, the game will not launch at all — it's a hard requirement, not a preference.

Recommended Requirements

These are the specs where Star Citizen becomes genuinely enjoyable — stable 60+ FPS in open space and 45–60 FPS in cities and dense areas, with graphics settings at medium-to-high.

What the Specs Actually Mean in Practice

Star Citizen is not like most games. It's an always-online, procedurally streamed universe that is rendering entire cities, planetary atmospheres, and persistent player actions simultaneously. The performance demands are unusual even for high-end hardware.

At minimum specs

You will get into the game. Expect 20–30 FPS in populated city areas like Lorville or Area18, and 40–60 FPS in open space or on foot in quieter locations. Everything will be set to Low or Medium graphics. Loading into a city or landing zone will take noticeably longer. During busy server events or large player battles, frame rate will dip further. It's playable — but frustrating at times.

At recommended specs

This is where the game starts feeling like the experience CIG intends. You'll hold 50–70 FPS in most situations with medium-high settings, cities will load cleanly, and the gorgeous planetary vistas and space scenes will render properly. With an RTX 3080 or equivalent, you can push settings higher and start exploring things like temporal upscaling (DLSS, FSR) for extra headroom.

High-end and above

Even an RTX 4090 won't always peg 120 FPS — Star Citizen's bottleneck is frequently CPU-bound due to how the engine processes server state, physics, and NPC AI. High-end hardware shines most in single-player Squadron 42 content and in low-population servers. In a 30-player battle near a space station, everyone drops frames regardless of rig.

SSD Is Not Optional

This is the bluntest hardware warning we can give: do not install Star Citizen on a spinning hard drive (HDD). The game streams world data in real time as you fly or walk — the planet you're landing on is not loaded all at once, it's pulled from storage constantly as you move through it.

On an HDD, loading into a city can take 5–10 minutes. Quantum travel transitions stutter. NPCs and props pop into view long after you arrive. The game technically runs, but the experience is severely broken compared to an SSD install.

• SATA SSD: Acceptable — loads are reasonable, world streaming works correctly.
• NVMe SSD (PCIe Gen 3): Noticeably better — city loads in under 60 seconds, transitions are smooth.
• NVMe SSD (PCIe Gen 4, 5,000–7,000 MB/s): Best experience available — some city loads complete in 20–30 seconds.

If you're on an older system with only HDDs, a budget NVMe drive ($40–$60) dedicated to Star Citizen is one of the single best upgrades you can make before anything else.

RAM: 32 GB Is the Real Sweet Spot

The official minimum is 16 GB, and 16 GB does work. But Star Citizen's engine is notoriously RAM-hungry. During a typical session in a busy city or server, the game process alone can consume 18–24 GB of RAM. When physical RAM is exhausted, Windows begins using the page file (virtual memory on the SSD) — and that swap activity causes stutters and frame drops that no GPU upgrade can fix.

With 32 GB of RAM, the game has room to breathe. Session stability improves significantly, especially on longer play sessions where memory usage creeps up over time. If you're building a PC and asking "should I get 16 or 32 GB for Star Citizen?" — the answer is 32 GB, without hesitation.

RAM speed matters less than quantity here. DDR4-3200 CL16 (a common budget spec) is perfectly fine. Dual-channel configuration (two sticks rather than one) does help the CPU's memory bandwidth, so two 16 GB sticks beats one 32 GB stick if you have the choice.

Graphics Settings for Lower-End PCs

If you're playing on minimum or near-minimum hardware, the right settings adjustments can recover a significant amount of performance. Here's what to change first and what to leave alone.

Lower these first (biggest FPS gains)

• Volumetric Clouds: Set to Medium or Low. This single setting has a dramatic impact on GPU load during atmospheric flight and is barely noticeable at lower settings from the cockpit.
• Shadows: Set to Medium. High and Ultra shadow settings are expensive and improvements are subtle in most gameplay situations.
• Screen Space Reflections (SSR): Set to Low or Off. Reflective surfaces look slightly less shiny, but reflections at High/Ultra are a significant GPU drain.
• Motion Blur: Off. Has no meaningful FPS impact but many players turn it off anyway for clarity — and it's one less thing to render.
• Resolution Scale / Upscaling: Enable DLSS (NVIDIA), FSR (AMD), or XeSS (Intel). Using Quality or Balanced mode can recover 20–40% more FPS with minimal visible quality loss.

Keep these at Medium or above (affect gameplay)

• Object LOD / Draw Distance: Too low and distant enemies, ships, and markers become invisible — a real combat disadvantage.
• Texture Quality: Low textures make the game look rough and can paradoxically hurt performance if VRAM is sufficient. Keep at Medium.
• Field of View: Leave at your preferred setting — this is comfort, not performance.

Download Size and Installation

Star Citizen is a large install and grows with each major patch. As of mid-2026, expect:

• Download size: Approximately 80–120 GB download (compressed), depending on your current patch version and what's cached.
• Installed size: 100–130+ GB on disk. RSI recommends 100 GB minimum free space, plus an extra 10 GB for the Windows page file. A 250 GB dedicated drive works; 500 GB is more comfortable.
• RSI Launcher: You download and install the free RSI Launcher from robertsspaceindustries.com. The launcher handles all patching from there.

Shader compilation on first launch

The very first time you launch Star Citizen (and after major patches), the game compiles shaders on your GPU. This process takes 15–45 minutes on most systems before you can play. A progress bar appears on the loading screen — it is not frozen, even when it appears to stall. Do not close the game. This is completely normal. Subsequent launches skip this step and load within a couple of minutes.

macOS and Linux

macOS is not supported and there is no Mac version of Star Citizen, either now or announced for the future. Cloud Imperium Games has never indicated macOS support is planned.

Linux has no official support either. However, the Star Citizen community has maintained unofficial compatibility through Proton (Valve's Windows compatibility layer for Linux). The experience ranges from "surprisingly functional" to "completely broken" depending on your distro, GPU driver, and the specific game patch. Community resources for Linux players include the Star Citizen subreddit and dedicated threads on Spectrum. If you want a supported, stable experience: use Windows 10 or 11.

Try Before You Buy — Free Fly Events

Here's the best advice for anyone unsure whether their PC can handle Star Citizen: test it before spending money. Cloud Imperium Games runs periodic Free Fly events where anyone can download and play the game for free — no purchase required — for a limited window, typically one to two weeks.

Free Fly events are your opportunity to load into Stanton, fly a loaner ship around ArcCorp or Crusader, check your frame rates in a city, and decide whether your hardware delivers the experience you want. You can check upcoming Free Fly dates and get notified at freeflyevent.com.

If your PC struggles during a Free Fly event, you'll know exactly which component is the limiting factor before committing to a game package. That's valuable information — and it's free.
