# [Windows 8.1 x64] Cyberpunk 2077 2.31 Steam compatibility patch I am publishing an experimental compatibility package for **Cyberpunk 2077 2.31 on Windows 8.1 x64**, tested against the Steam public build `20383525`. ** Download has been taken down **ZIP SHA-256:** `5D8543335269D86B7456B60B6E6A3908C6C296B186DB93F8EF25EA38D371745E` > This release was tested only on **Windows 8.1 x64**, so that is the only > operating system for which it is currently recommended. The installer rejects > other Windows versions and unsupported game files. ## What it fixes The package provides a D3D12On7 raster path for the tested Steam build and fixes the known presentation problem where Cyberpunk appears frozen and updates only when another window is dragged over it. The game can be launched normally with Steam's **Play** button after adding the launch option printed by the installer. ## Performance On my tested machine, performance is close to running the game on Windows 10. It is dramatically better than my older Cyberpunk 1.63 compatibility setup, which delivered roughly half performance on the same machine. This is an observed real-world comparison, **not a controlled or standardized benchmark**. Results will vary with GPU, driver, settings and system setup. ## Tested setup - Windows 8.1 x64 - Cyberpunk 2077 2.31, Steam build `20383525` - GeForce RTX 2060 - NVIDIA driver `474.11` - 1920 x 1080 - Raster rendering only Other GPUs and drivers, GOG/Epic releases, hybrid graphics and other operating systems have not been tested. ## Required: official D3D12On7 1.1.0 package Download Microsoft's official [`Microsoft.Direct3D.D3D12On7` 1.1.0 NuGet package](https://www.nuget.org/packages/Microsoft.Direct3D.D3D12On7/1.1.0) separately and save the unchanged file next to `Install.cmd` as: `Microsoft.Direct3D.D3D12On7.1.1.0.nupkg` Expected package SHA-256: `C0C4D597537ECC1C777FA3B5523E5CCDE0B9984B88FB9F37B2385E1D687BF536` The Microsoft package is not bundled with this patch. ## Required: SecondSystem SecondSystem must already be installed and active. **It is not bundled with the patch.** Obtain it separately here: [SecondSystem from win32's Patreon](https://patreon.com/win32?utm_medium=clipboard_copy&utm_source=copyLink&utm_campaign=creatorshare_fan&utm_content=join_link) Please support its developer and follow the terms provided with it. ## Installation 1. Extract the complete ZIP. 2. Download the official D3D12On7 package above and place it beside `Install.cmd`. 3. Install and activate SecondSystem. 4. Exit both Cyberpunk 2077 and Steam completely. 5. Run `Install.cmd`. 6. Copy the exact Steam Launch Options value printed at the end. 7. Paste it into **Steam > Cyberpunk 2077 > Properties > General > Launch Options**. 8. Start the game with Steam's **Play** button. Do not append custom arguments; the included launcher intentionally uses only the fixed, validated command line. The installer validates the exact game/runtime hashes and stops before changing anything if the files are unsupported. It keeps all compatibility files local to the game directory and creates a verified uninstall record. ## Important limitations The following features must remain disabled: - Ray tracing and path tracing - DLSS - NVIDIA Reflex - Frame Generation, including XeSS Frame Generation This release is for raster rendering. Cyberpunk 2.31's newer Agility SDK path is not a Windows 8.1 target, so modern features that depend on it are outside this patch's scope. ## Removal and game updates Close the game and Steam, run `Uninstall.cmd`, then clear Steam Launch Options. The uninstaller restores any files it backed up and reverses its SecondSystem mappings. The package is locked to Steam build `20383525`. The launcher compares the full contents of the current executable with its validated local copy and refuses a mismatch. After a Steam update, uninstall this release and wait for a version explicitly validated for the new build; do not remove the version/hash safety checks. ## What is and is not included The ZIP contains the original open-source proxy, launcher, installer scripts, source code, documentation and notices. It does **not** include: - Cyberpunk 2077 files - Microsoft D3D12On7 or D3D11On12 binaries - SecondSystem - Steam files - any DRM bypass A legal Steam copy of the game is required. The installer extracts the runtime inputs from the official NuGet package separately supplied by the user and creates a local working copy. Microsoft terms still apply and may restrict this use or modification; this is not legal advice. Full installation, troubleshooting, technical and checksum information is in the included `README.md`.

ah jeez thanks for warning me appreciate it

The Advanced tab in New Moon appears completely empty when using the last supported version of Pale Moon's German language pack (28.10.0). I don't know if New Moon is still being developed with these LP's in mind, sorry if this turns out to be a useless forum post.

A brilliant solution! The German software is always on top! I know newer versions, up to recent years, still work via CMD, it's just the interface that is not loading properly.

My driver is from 2021, oen of the last ones for 7 and 8. RDR2 runs perfectly fine. DXVK, I tried today, no result. Looks like the game can be added to a full no-support list!
