Half-Life 2 RTX: Is It Out? What the Demo Contains

Half-Life 2 RTX was announced on August 22, 2023, at gamescom. NVIDIA's announcement post called it "early in development."

Three gamescoms have come and gone since that reveal, the 2026 show among them, and the thing you can install is still a two-chapter demo. Its most recent patch, Update #4 on October 23, 2026, was its first since May 8, 2025, and Orbifold describes it as "a technical update to the existing demo, with no additional levels or content." That is not a knock on the people building it. It is just the fact that decides whether you should clear 50 GB tonight, and it is the one a trailer will never tell you.

The short answer

There is no full release, no release date, and no announced window. One free Steam entry exists, it holds a demo of two chapters, and its only update since May 2025, Update #4 on October 23, 2026, moved it onto a newer RTX Remix runtime without adding any levels.

What Half-Life 2 RTX actually is

It is not an NVIDIA product and it is not a Valve product. Orbifold Studios builds it, using NVIDIA's RTX Remix toolset, and Orbifold's own site describes the studio as "a collective of developers who love Half-Life, formed by the teams behind Half-Life 2: VR, Half-Life 2: Remade Assets, Project 17, and Raising the Bar: Redux."

That first name should look familiar. The people behind the Half-Life 2 VR Mod are part of the same collective doing this — two very different total conversions of the same 2004 game, from an overlapping bench of modders.

Steam classifies it the same way it classifies the VR mod: an app of type mod, attached to Half-Life 2 (app 220), costing nothing. The store copy calls it "a free DLC for all Half-Life 2 owners." Orbifold's launch announcement was addressed to "Owners of Half-Life 2," so the base game is the entry fee — and Half-Life 2 is a $9.99 purchase.

The scope Orbifold states for the finished project is total: "we're updating every texture, model, and level, adding extra geometric detail to buildings and surfaces to realistically interact with fully ray-traced lighting." Their framing for what stays untouched is equally direct — "we're remaking the entirety of Half-Life 2 graphics, while leaving its beloved gameplay untouched." That is a statement of intent about a game that has not shipped, so read it as one. Nothing about the finished remaster can be judged yet, because there is nothing finished to judge.

What shipped, and what did not

The demo went live on March 18, 2025. It covers levels from two chapters: "We Don't Go To Ravenholm..." and Nova Prospekt.

Both are lighting-led levels rather than daylight ones: Ravenholm is built around darkness and pooled lamplight, Nova Prospekt around hard interior geometry and shafts of window light. If you want the flat-game versions of them first, the Ravenholm guide and the Nova Prospekt guide cover both.

The hardware bar is the real story

Half-Life 2 itself is a $9.99 game from 2004. Here is what the ray-traced version of two of its chapters asks for, straight off the Steam page:

Read the GPU row twice. The minimum is stated with DLSS on, not as a native-resolution figure. Rechecked on October 25, 2026, two days after Update #4, every row is unchanged, and the processor rows still name only Intel and AMD chips even though the update added support for compatible Windows on ARM systems.

The storage line is worth its own sentence. Orbifold's March 20, 2025 hotfix exists purely to fix a display bug in it, and states the real figure: "The correct download size of 44.1GB is now displayed during installation." Two chapters of a 2004 game, 44.1 GB on the wire. Orbifold's notes for Update #4 give no new size, so the 50 GB on the store page is the number to budget against.

For measured framerates, DSOGaming ran a launch-day benchmark published March 18, 2025 on a Ryzen 9 7950X3D with 32 GB of DDR5. Their conclusions, theirs rather than mine: at native 1080p you need an RTX 5090 for a smooth run; at native 1440p, none of the GPUs they tested managed it; at 4K with DLSS 4 Performance mode and no frame generation an RTX 5090 stayed smooth but dipped to 54 fps in the most demanding area they could find; and adding 2x Multi Frame Generation on top of that took the same card past 98 fps. That was the launch build, before the two lighting patches and before Update #4 moved the demo to a newer runtime, so treat it as a shape rather than a current number.

The in-game lever for all of this is Alt+X, which opens the RTX Remix settings menu with the graphics and DLSS presets in it. Orbifold's launch post points at that key specifically, saying the presets are meant to cover cards "dating back to the GeForce RTX 3060 Ti." Update #4 added more options to that menu, and Orbifold notes that "Available options depend on your hardware and driver": the new Frame Generation Preset C is listed for RTX 40 and RTX 50 Series GPUs and RTX Spark laptops, the 5x and 6x Multi Frame Generation modes for supported RTX 50 Series GPUs, and the Update #4 breakdown covers which card gets which.

The whole patch record, in one table

Six Community Announcements sit on that Steam feed: a pre-launch post on March 13, 2025, and the five below, which are every release Orbifold has announced as of October 25, 2026.

Update #4 went up at 15:32 UTC on October 23, 2026, 533 days after Update #3, and it is the latest post on that feed as of October 25, 2026. The Update #4 breakdown covers what each of those changes does and which GPUs can use it.

The lighting argument, in the developer's own words

The most interesting thing about this demo is not the ray tracing. It is that Orbifold shipped it as an instrument, took the results, and changed course in public.

Their April 1, 2025 note states the purpose plainly: "We released the Half-Life 2 RTX Demo as a way to get feedback from the community early to build the best remaster we can." The same note describes the first correction — a tonemapper bug had left "the displayed image to be over-brightened," and the fix meant "areas in shadow will feel much darker, while areas in light will still allow details to shine through without being overexposed and 'washed out'."

That was step one, and they said so: "This new tonemapper represents our first step in responding to community feedback, with many more adjustments to lighting and volumetrics to come in a future patch."

Step two arrived May 8, 2025, and it went further than a tone curve. Their words: "This patch implements a new lighting arrangement that both takes into account the new tonemapper, as well as directly addressing community feedback regarding light levels and fog intensity." The stated result: "By and large, these changes result in Ravenholm being darker, with more intentional authorship of light and shadow."

Two lighting passes in the 51 days between launch and that patch, and Ravenholm is the level Orbifold singled out as the one that came out darker. Whatever else you take from this project, that is a useful data point about what "just add ray tracing" actually costs: the renderer being physically correct and the level looking right are two different jobs. It is also why any screenshot of this demo taken before May 8, 2025 is showing you a build that has since been replaced.

What the Steam numbers say

Reception is easy to check rather than guess at, so here it is measured rather than characterised. As of August 30, 2026, the Half-Life 2 RTX Steam entry carries 8,983 reviews: 5,069 positive and 3,914 negative, which is 56.4% positive and puts it in Steam's Mixed band. Its store page still read Mixed on October 25, 2026, two days after Update #4.

For scale on the other axis, the Steam API reported 8 people in the demo on August 30, 2026, against 1,908 in Half-Life 2 itself. At 22:05 UTC on October 25, 2026, two days after Update #4, it reported 19 in the demo against 1,878 in Half-Life 2. Update #4 changed the renderer, not the content, so what you would be downloading is still the same two-chapter sample that launched in March 2025.

Set that against the VR Mod from the overlapping team, checked on August 30, 2026: 7,758 positive out of 7,922 reviews, Steam's Overwhelmingly Positive band, on a comparable sample size. Same broad group of people, two very different verdicts on two very different things — one a finished conversion of the whole game, the other a two-chapter slice of an unfinished one.

Bugs the team was still listing

The May 8, 2025 announcement carried an "Investigating Reported Issues" block. Orbifold's Update #4 notes on October 23, 2026 carry no known-issues list at all, so the May block is still the latest one the team has posted, and nothing in Update #4 says these four are fixed:

• Some game overlays can crash the demo. The team recommends disabling overlays, and names FrameView as safe for performance measurement.
• Steam's F12 screenshot hotkey will crash it. They suggest NVIDIA app's Alt+F1 screenshot, Alt+F9 recording, or OBS Display Capture instead.
• A first-launch crash tied to shader compilation. Their fix: start the game again.
• With Desktop Capture active in the NVIDIA app's video capture settings, recording can stop working until the demo is restarted.

If you install this, disable your overlay and rebind your screenshot key before you do anything else. That is four minutes of setup against a known crash.

Four things this gets confused with

The first row is the one worth separating carefully, because both get called a Half-Life 2 remaster and only one of them is finished. The anniversary update is Valve's, it is in your copy of the game already, and the Lost Coast guide covers what it moved where. Half-Life 2 RTX is a community project and is not in your copy of anything.

Quick Action Checklist

• There is no full release. Only a demo exists, and no release date or window has been announced for the finished game.
• The demo covers levels from two chapters: "We Don't Go To Ravenholm..." and Nova Prospekt.
• It is free, but you need Half-Life 2, which is a $9.99 purchase.
• Budget the 50 GB of free space the Steam page asks for. Orbifold's last stated download size, 44.1 GB, dates from March 2025, and its Update #4 notes give no new figure. Steam lists Windows only, though Update #4 added support for compatible Windows on ARM systems.
• The stated minimum GPU is an RTX 3060 Ti with DLSS on — the figure already assumes upscaling.
• Press Alt+X in-game for the RTX Remix settings menu and its graphics presets. Since Update #4, what appears there depends on your hardware and driver; the Update #4 breakdown covers which card gets which option.
• Disable game overlays and stop using F12 for screenshots first; both are on the team's own known-crash list.
• If you last looked at this demo before May 8, 2025, you have not seen the current lighting — it changed twice, with a tonemapper fix on April 1 and a full relight on May 8. Update #4 on October 23, 2026 then reduced jagged self-shadowing on curved and low-polygon surfaces and added optional rendering modes, without new levels or content.
• Do not read the Steam review score as a verdict on the finished remaster. It was Mixed at 56.4% across 8,983 reviews on August 30, 2026, and still Mixed on October 25, for a two-chapter slice of an unfinished game.
