Data basis: Egosoft’s announcement “Upcoming Changes to X4: Foundations Minimum System Requirements,” posted to the game’s Steam news feed on 1 July 2026; the Khronos Group’s Vulkan 1.4 release announcement; and the Steam Hardware Survey video-card page as published for July 2026, read live on 2026-08-31. Percentages below are copied from that survey page on that date and will drift as it updates monthly.
Egosoft is moving X4: Foundations to Vulkan 1.4 in the next major update after 9.00, and with it the minimum GPU requirement rises to “NVIDIA GTX 1060 or AMD RX 5300 or equivalent (Vulkan 1.4 Support required).” The announcement then adds one reassuring sentence:
Based on recent Steam Hardware Survey data, we are confident that this change will only affect a small fraction of our active players.
That sentence is almost certainly true. It is also, as published, not checkable — because the Steam Hardware Survey does not report Vulkan support, in any version, anywhere on its public pages.
What the survey actually publishes
The video-card page groups every reported GPU into exactly six capability tiers. These are the July 2026 figures, read from the live page:
| Tier published by the Steam Hardware Survey | July 2026 |
|---|---|
| DirectX 12 GPUs | 91.37% |
| DirectX 11 GPUs | 0.46% |
| DirectX 10 GPUs | 0.23% |
| DirectX 9, Shader Model 2b and 3.0 | 0.01% |
| DirectX 9, Shader Model 2.0 | 0.00% |
| DirectX 8 and below | 7.93% |
Six tiers, all of them DirectX. There is no Vulkan row, no driver-version row, and no per-card capability flag. (The 7.93% in the bottom row is also worth treating with suspicion rather than reading as genuinely ancient hardware — it is the bucket where anything the survey cannot identify tends to land.)
The gap this leaves is not a technicality. DirectX 12 support says nothing about Vulkan 1.4 support: a 2014-era card can sit in that 91.37% and still be nowhere near a Vulkan 1.4 driver, because Vulkan 1.4 is a specification the Khronos Group only released on 3 December 2024. Whatever internal data Egosoft used to reach “a small fraction,” a reader cannot reproduce it from the source named in the announcement.
The two floors are not the same floor
The named cards deserve a second look, because they are four years apart.
The GTX 1060 is a July 2016 Pascal card — one of the best-selling GPUs Steam has ever surveyed, still holding 1.53% of its DirectX group in the July 2026 numbers. The RX 5300 is a 2020 RDNA 1 part built on Navi 14, sold with 3 GB on a 96-bit bus and pushed primarily through OEM systems rather than retail shelves. Very few people went out and bought one.
So the AMD side of the requirement is best read not as “the RX 5300” but as “RDNA 1 or newer” — which quietly places AMD’s whole Polaris and Vega line, cards contemporary with or newer than the NVIDIA minimum, below the bar. An RX 580 owner and a GTX 1060 owner bought comparable cards in the same era; only one of them is named as still supported.
There is a structural reason to expect that asymmetry rather than to treat it as an oversight. AMD ships Polaris and Vega on a separate driver release line from its mainline Adrenalin driver — the release notes for those parts are published as their own documents, titled “for Polaris & Vega,” on a different cadence from the main branch. A GPU on a maintenance driver line is not where new API versions arrive.
What you can check yourself, and get a real answer
The survey cannot tell you whether your card clears the bar. Your own driver can, and it takes a minute:
vulkaninfo— installed with the LunarG Vulkan SDK, and already present on most Linux systems. Run it and read theapiVersionline for your device. If it reports 1.4.x, you are above the line; 1.3.x and you are not.- GPU-Z (Windows) — the Advanced tab has a Vulkan section that reports the API version the installed driver exposes. Same reading.
- Update the driver first, then re-check. Vulkan version is a property of the driver, not of the silicon alone. A card that reports 1.3 on a two-year-old driver may report 1.4 on the current one — and on a maintenance-line card, it will not.
Do this before the update ships rather than after, because there is a decision attached to the answer.
Nobody loses access
The part of the announcement that got least attention is the one that matters most if you come up short. Egosoft commits, in bold in its own post, that “if you are currently playing on older hardware, you will not lose access to the game.” Legacy builds stay available through Steam’s Game Versions & Betas branch system — right-click X4 in the library, Properties, then the Game Versions & Betas tab, and pick the designated legacy build.
That is a materially different choice from the one other studios have made under similar pressure. When Project Zomboid hit security work it could not backport, its legacy builds were pulled from circulation entirely for months; Egosoft is treating the old build as a supported destination instead of a liability. The trade-off lands where you would expect: a legacy X4 branch does not receive the content updates the new technical foundation is supposed to enable.
For what the 9.00 update itself changed before any of this, see the X4 9.00 ship stat changes. For working out which parts of the game you actually need, see the X4 DLC matrix.
What we could not confirm
- The share of X4 players affected. We deliberately do not put a number on it. The Steam Hardware Survey’s per-model percentages are normalised within each DirectX group rather than across the whole population, so they cannot be summed into a global share without the group weights, and mapping every listed model to a Vulkan 1.4 driver is not something the published data supports. Egosoft has data we do not; the point of this page is that the source it cited is not that data.
- The exact Vulkan version AMD’s Polaris and Vega driver line exposes. AMD publishes those release notes separately from the mainline driver, which is verifiable, but we could not read a current version number off a primary AMD page and will not repeat one second-hand.
- When the update ships. The announcement says “the next major update after 9.00” and gives no date.
- Whether the legacy branch is frozen or maintained. The post says access continues; it does not say whether legacy builds receive fixes.
