Quick answer

CIG lists 16GB RAM and a 150GB+ SSD as minimums, with 32GB DDR4 and an 8GB DirectX 12 GPU recommended. Use those as the official baseline. RAM pressure and storage activity are useful first checks for hitching, but game, server, driver and overlay faults can produce similar symptoms.

Star Citizen's published baseline

  • CIG lists 16GB RAM as minimum and 32GB DDR4 as recommended.
  • A 150GB+ SSD is required at both tiers; NVMe is my new-build preference.
  • The recommended GPU line is DirectX 12 with 8GB VRAM. It is not a resolution-specific FPS target.
  • For hitching, check memory pressure and disk activity alongside the game logs, drivers and server conditions.
  • Check your PC against the minimum, then decide what to measure if it already qualifies.

Use the official requirements to check compatibility, then diagnose the machine you have. Buying a GPU before identifying the slow part can leave the same hitch in place. My own setup is described below; it is one system, not a controlled comparison of every RAM capacity or storage interface.

The official minimum requirements

The CIG minimum and recommended sheet was updated September 23, 2026; I checked it October 12. TechFuel rechecked the requirements on November 5. Specs can change during development. The sheet gives no benchmark scene or target frame rate.

ComponentOfficial minimum
OSWindows 10, latest service pack
CPUQuad-core: Intel i7 Haswell or later; AMD Excavator or later
GPU4GB VRAM; driver support for Direct3D 11.1 and Vulkan 1.2
RAM16GB
Storage150GB+ SSD

CIG’s GPU examples are the GTX 1060, RX 5700, RX Vega 56, RX 460, Intel A380 and UHD Graphics 730. Its CPU note requires AVX, AVX2 and FMA3 instructions, and the processor and OS must be 64-bit. The launcher guide repeats those CPU instructions.

The recommended row lists Windows 10 or 11, a quad/eight-core CPU (Haswell-or-later i7 or Ryzen 5-or-later), an 8GB DirectX 12 GPU and 32GB DDR4. The SSD requirement is the same.

Check your PC before buying a part

Use the PC, driver and installation you actually plan to use. Choose “unknown” when you only know a product family or marketing label. This worksheet takes manual answers; it does not inspect your PC or upload a report.

  1. Windows. Run winver and check System Information → System Type. CIG lists 64-bit Windows; the launcher supports Windows 10 or 11. macOS and Linux are outside official client support.
  2. CPU and instructions. Identify the exact CPU, its core count and instruction support. Check the stated quad-core model baseline and all three flags: AVX, AVX2 and FMA3. A name like “i7” without the generation is not enough.
  3. GPU, driver and memory. On the adapter used by the game, verify the 4 GB VRAM line and driver support for both Direct3D 11.1 and Vulkan 1.2. If the only evidence is a DirectX version on the System tab, choose unknown. CIG names UHD Graphics 730 but also prints a VRAM floor: a listed example alone does not resolve a shared-memory configuration.
  4. Installed system RAM. Compare installed system memory with 16 GB. A machine with 16 GB can meet the minimum while remaining below the 32 GB recommendation. GPU memory is a separate figure.
  5. Installation storage. Find the drive containing the actual game library, then check the drive type and available space. CIG lists a 150 GB+ SSD; an HDD-only installation misses the storage requirement even if there is space on another SSD.

Where to find missing evidence: CIG’s launcher guide walks through DXDiag and System Information. For a CPU with an uncertain generation or instruction set, compare the exact SKU with its manufacturer’s specifications; Microsoft Coreinfo can also report processor features. On a laptop with two adapters, record the one selected for the game. A Windows DirectX runtime label does not establish the adapter’s hardware feature levels or Vulkan capability. If you already have LunarG’s vulkaninfo, vulkaninfo --summary lists GPUs separately: read the selected device’s API version, not just the loader/instance version. Leave a field unknown until you can substantiate it.

For example, a machine with 16 GB of RAM, a documented compatible GPU and an HDD-only game library misses the SSD requirement. Buying more VRAM would not fix that mismatch. Conversely, a 32 GB machine on an SSD with undocumented driver support is an unknown, not a recommendation to replace the graphics card. These are illustrative cases, not tested PCs.

Mac, Xbox and PlayStation support

Star Citizen’s supported client is Windows PC. CIG’s current minimum-requirements page explicitly says the game is unavailable for macOS and Linux, and its game and launcher requirements list Windows 10 or 11. CIG does not document an Xbox, PlayStation 4 or other PlayStation client in those support requirements. That describes current support; it is not a prediction about future platforms.

RAM: start with CIG’s recommendation

32GB is the sensible starting point for a new build because it matches CIG’s published recommendation. That is enough reason to plan for it. This page has no named-build comparison showing a universal 18-24GB process footprint or proving that every 16GB system will stutter.

For an existing machine, watch total memory use and paging during the troublesome session. Memory pressure makes RAM a useful diagnostic branch; a process-memory figure by itself does not prove that disk paging caused a hitch. Close unnecessary background applications and compare the same route again. Keep a system-managed pagefile with free SSD space rather than disabling it to force the issue.

Once capacity is the identified constraint, use the DDR5 buying guide to compare kit layouts and timings.

Storage: an SSD is required

CIG requires an SSD. Its sheet specifies 150GB+, with no SATA-versus-NVMe load-time claim. Budget additional space for updates, the pagefile and a separate PTU install if you use one.

I would choose a compatible NVMe for a new build. If the game already lives on a SATA SSD, inspect disk activity and the logs before replacing it. Late assets, missing terrain and long loads can involve storage, but they can also be game or server faults. This guide supplies no paired drive test that establishes a twofold NVMe speedup.

For launch or patch failures, use the log-first Error 5007 guide to match the error to a cause.

Choosing hardware for your resolution

The official 8GB recommended GPU figure is not a 1080p, 1440p or 4K tier. This page has no reproducible GPU/CPU comparison tied to a game build, so the former card and CPU tier table cannot establish an FPS target.

Keep LIVE and PTU results separate. CIG’s October 9 deployment records 4.10.2-live.12881860. Its 4.10.3 test-channel notes identify 4.10.3-PTU.13107423. These are examples of two distinct builds, not a claim that either is the newest build installed on your machine. A session on one cannot establish a settings gain on the other. Copy your own build/channel from the launcher or saved game log before comparing runs. Download the blank comparison sheet for two passes on the same route.

Record the game build. Look for a test that also states the location and route, resolution, render scale, graphics API, settings used and frame-time results. Compare equivalent runs, including whether the test used upscaling. A quiet flight and a crowded landing zone can give very different results. Repeat the same route. Change one setting at a time so that the result tells you which change helped; averages alone can hide the hitch you want to fix.

The GPU reviews help compare hardware more broadly. My 7800X3D and RTX 5080 build is an example configuration; the firsthand account below is scoped to that machine.

Is your PC GPU-bound or something else?

Start with a repeatable symptom, then test the likely branch.

  • Stutter or late assets: check memory pressure, paging and disk activity first. Also read the timestamped game log and check the current build’s known issues. RAM or storage is a hypothesis, not the cause of every hitch.
  • Frame rate improves when you lower resolution or render scale in the same scene: investigate GPU load and settings. Keep the server and route as consistent as possible; see the Star Citizen settings guide.
  • Trouble confined to busy locations or particular sessions: compare another location and server before buying hardware. CPU load, game behavior and server conditions can all be involved.

CIG documents overlay and application conflicts that can cause crashes or graphics faults. Match those to the symptom too.

Star Citizen keeps crashing: collect the right log first

CIG’s support route starts with the failure files rather than a generic reinstall. After a crash, open %localappdata%\Star Citizen; the crash handler stores payload.zip there when it completes. CIG says the package can contain the saved DXDiag, game.log, gpu_error.log and other crash-time files. The current launch log is under the Star Citizen install, with older copies in LIVE\logbackups; the RSI Launcher keeps log.log under %appdata%\rsilauncher\logs. The exact locations and support-sharing boundary are in CIG’s file-collection guide.

Read the timestamp around the crash, then match the branch: update Windows and the GPU driver for a local compatibility fault, check free SSD and page-file space for memory pressure, and remove an application or overlay only when the log or CIG’s unsupported-applications list points there. Preserve the files before another launch overwrites the current log. A server disconnect is a different event from a client process crash.

My own setup, and what mattered

I run Star Citizen on a 7800X3D / RTX 5080 build with 32GB of RAM on an NVMe drive. The lesson from living with it: the GPU is the part I think about least. The things that decided whether a session was smooth were having enough RAM to never touch the pagefile and a fast enough SSD that assets streamed in before I reached them. If you only change one thing on an older machine, make it 32GB of RAM; if you can change two, make the second an NVMe SSD. The graphics card is where you spend what is left, sized to the resolution you actually play at.

That is the author’s account of one machine. It has no matched patch, route or before/after frame-time trace here; use the checklist and your symptom to decide whether the same change addresses your case. If collecting diagnostics for a support case, CIG requests the original files directly in the support ticket. This worksheet does not need those files.

Frequently asked questions

What are the official minimum requirements for Star Citizen?
CIG’s sheet, updated September 23, 2026 and checked November 5, lists 64-bit Windows 10, a quad-core Intel i7 Haswell-or-later or AMD Excavator-or-later CPU with AVX, AVX2 and FMA3, a 4GB GPU whose driver supports Direct3D 11.1 and Vulkan 1.2, 16GB RAM and a 150GB+ SSD. Its GPU examples include GTX 1060, RX 5700, RX Vega 56, RX 460, Intel A380 and UHD Graphics 730. These are compatibility requirements, not an FPS guarantee.
How much RAM do I need for Star Citizen?
CIG recommends 32GB DDR4 and lists 16GB as the minimum. I would plan a new build around 32GB, then check total memory use and paging in the sessions that hitch before buying more. This page does not provide a version-bound RAM-capacity benchmark, so 32GB is the published recommendation rather than a universal measured performance floor.
Does Star Citizen need an SSD or NVMe?
CIG requires a 150GB+ SSD. The published requirement does not mandate NVMe or promise a load-time ratio against SATA. A compatible NVMe is a reasonable new-build choice; an existing SATA SSD needs a workload check before replacement. Leave room for updates and the pagefile, and investigate logs if assets or loading fail.
Is Star Citizen GPU-bound or CPU-bound?
It depends on the scene, resolution, settings, game build and server. Compare the same location at a lower resolution while watching frame time, GPU load, memory pressure and disk activity. That can identify the next test; a hitch or a crowded city alone does not prove which component is limiting performance.
What GPU do I need for Star Citizen in 2026?
CIG’s current sheet lists a 4GB DirectX 11.1 GPU as minimum and an 8GB DirectX 12 GPU as recommended. It does not map those to 1080p, 1440p or 4K performance tiers. This page has no same-build, same-scene GPU comparison, so choose a specific card using a benchmark that states resolution, render scale, settings and frame-time results.

Update log
  • 2026-11-05 — Added the manual minimum-spec checklist and build-specific comparison worksheet. Rechecked CIG’s requirements and log-sharing guidance; separated a published LIVE deployment from a later PTU example. The author’s original setup remains unchanged. No game was run and no frame rates are reported.
  • 2026-10-12 — Rechecked CIG’s September 23 requirements, including its Vulkan driver note and example cards. Removed unbound 18-24GB graphic, SATA/NVMe speed ratio and resolution-specific hardware guarantees. Separated CIG’s recommendations from the unchanged owner setup and replaced categorical RAM/SSD diagnoses with observable tests. No game benchmark was added.
  • 2026-08-15 — This re-checks the 2026-08-14 correction above. I re-derived the whole sheet from the same primary source (support.robertsspaceindustries.com article 360042417374, Zendesk API, edited 2026-07-27): the storage, Excavator-minimum, and Direct3D-11.1-and-Vulkan-1.2 corrections are all confirmed exactly as shipped. Two remaining gaps are now closed. CIG lists a sixth minimum-spec example, Intel UHD Graphics 730, which had been dropped from the table and the FAQ answer, so an integrated-graphics reader was being told they fell below a minimum CIG says they meet. The note above described ‘Ryzen 5 1600’ as CIG’s recommended tier when CIG’s recommended row reads ‘AMD: Ryzen 5 or later’ and names the 1600 SKU nowhere. No spec value changed.
  • 2026-08-14 — I corrected the official-minimum spec table and the matching FAQ answer against CIG’s own published sheet (support.robertsspaceindustries.com article 360042417374, last edited 2026-07-27, re-derived from both the Zendesk API and the rendered page). Three errors: (1) storage was stated as ‘100GB+ free on an SSD’ in the labeled-official table and FAQ while the same page’s body section said 150GB+ – CIG lists ‘150+ GB SSD required’ at both the minimum and recommended tiers, so the low figure was wrong and self-contradictory; (2) the AMD minimum CPU was given as ‘Ryzen 5 1600’ – the published minimum is ‘Excavator or later’, and CIG names no such SKU at either tier (their recommended row reads ‘AMD: Ryzen 5 or later’); (3) the minimum GPU was illustrated with ‘RX 580 class’, which CIG does not list – their stated examples are the GTX 1060, RX 5700, RX Vega 56, RX 460, Intel A380 and UHD Graphics 730, and the GPU line is a driver requirement for Direct3D 11.1 and Vulkan 1.2, not either/or. I also tightened the recommended-tier sentence: CIG lists Windows 10 or 11 (not Windows 11 only), a quad-to-eight-core CPU (not ‘8-core’), and 32GB of DDR4. No performance guidance or first-hand claim changed.
