Star Citizen’s development reporting has described Vulkan as the renderer direction, but current RSI documentation does not establish a date for retiring DirectX 11. RSI still lists Direct3D 11.1 driver support in the minimum requirements and provides DirectX 11 as a workaround for certain Vulkan problems. Vulkan is therefore not evidence that DX11 has already been phased out, and a recommended GPU that supports DirectX 12 does not mean the game renders through DX12.
Does Star Citizen use Vulkan, DirectX 11 or DirectX 12?
The available official information points to Vulkan as part of the renderer’s development direction, while DX11 remains present in current requirements and support guidance. It does not establish that DX11 has been retired or give a retirement date. Nor does it establish that Star Citizen uses DirectX 12 as its rendering API.
RSI’s minimum requirements, updated September 23, 2026, call for a graphics driver supporting both Direct3D 11.1 and Vulkan 1.2. The recommended GPU line specifies a DirectX 12-compatible graphics card with 8 GB of VRAM. That describes the graphics card’s capability; the requirements page does not say the game renders through DirectX 12. RSI’s system requirements also caution that specifications may change while the game is in development.

| Recommended | Windows 10 or 11; 32 GB DDR4; DirectX 12-compatible graphics card with 8 GB VRAM. |
These are RSI’s published system specifications, not a promise of a particular frame rate. RSI says performance and stability can vary with location, server population, background applications and network conditions. Check the current requirements page before upgrading, since the company says the specifications can change.
Is DX11 being phased out?
There is no DX11 phase-out date in the current official material covered here. RSI’s troubleshooting guidance still explains how to switch back to DirectX if a Vulkan change prevents the game from launching, and its Alpha 4.10.1 known-issues page lists DirectX 11 as a workaround in particular Vulkan-related cases. That makes DX11 a documented fallback in those contexts; it does not guarantee that every future release will retain it.
Why Vulkan became part of the renderer work
In its April 2021 monthly report, CIG described Vulkan backend work aimed at reaching parity with DirectX 11. It said: “Progress was made on the Vulkan backend to achieve parity with DirectX 11, which requires a pass over all shaders to remove a handful of legacy DirectX 9 features that are no longer supported.” The report also discussed ongoing Gen12 renderer work. This is historical development context, not a present rollout status or a commitment to remove DX11 on a particular date. Read the April 2021 monthly report.

When should you switch from Vulkan to DirectX 11?
Vulkan is not universally faster or less stable based on the official notices cited here. RSI’s Alpha 4.10.1 known-issues page, updated September 16, 2026, records specific Vulkan crash and frame-rate reports, including an investigation involving NVIDIA driver version 616.56. For those cases, RSI suggested rolling back the driver or switching to DirectX 11; for reported frame-rate loss, it also suggested updating drivers or lowering resolution. These are issue-specific reports and workarounds, not a controlled comparison showing one API is generally better. See RSI’s Alpha 4.10.1 known issues.
If Vulkan prevents the game from launching
RSI’s Vulkan troubleshooting article, updated May 27, 2026, gives a configuration-file workaround to return to DirectX after switching to Vulkan causes a launch crash. Follow the current instructions in RSI’s article, since configuration details can change. Open RSI’s Vulkan troubleshooting guide.
If Vulkan fails to initialize
RSI says outdated Vulkan components can cause initialization problems and notes that some versions of Vulkan-1.dll may be flagged by Easy Anti-Cheat. Its guidance is to ensure the graphics drivers and Vulkan components are up to date. Consult the linked troubleshooting page for the current steps rather than replacing DLLs or downloading components from unofficial sources.

Do you need a new graphics card for Vulkan?
Not solely because Vulkan is mentioned. Start by checking whether your existing card and driver satisfy RSI’s current minimum requirements: at least 4 GB VRAM and driver support for Vulkan 1.2 as well as Direct3D 11.1. RSI’s minimum examples include NVIDIA 1060, AMD RX 5700, RX Vega 56, RX 460, Intel A380 and UHD Graphics 730. These are examples on RSI’s requirements page, not a guarantee of equivalent performance or an endorsement of a specific upgrade. The page also specifies 16 GB memory and an SSD with 150+ GB capacity as minimum system requirements.
What earlier patch notes do—and do not—show
Alpha 3.24.0 release notes recorded fixes for Vulkan renderer performance degradation and Vulkan-specific crashes, and suggested testing DirectX for frequent Vulkan crashes. Those notes show that Vulkan issues have been addressed in past patches; they do not establish current performance or a permanent API preference. Read the Alpha 3.24.0 release notes.
