Officially: Windows
Emulated: Linux, Steam Deck
Emulation on Linux is subject to varying performance and rendering artifacts depending on your hardware and software setup. It may run through Wine compatibility layer on almost any distro, but Steam’s Proton on a Ubuntu-based distro is recommended, as it has been proven in our testing to be the most trouble-free solution. The hardware requirements listed are the same for both Windows and Linux.
Installation: 4.7GB

A majority of Skyfear was developed using a 4 core processor and a GeForce GTX 750 Ti, which is old and long-proven hardware, to ensure performance and stability on a wide range of hardware at ages that can include 5 years or more. The hardware requirements listed are the same for both Windows and Linux.
The game will launch without Steam, but launching through Steam is required for online multiplayer.
There is currently a known issue regarding the game not wanting to run after installation if you’re computer uses a 10th generation or higher Intel CPU. This is because Skyfear uses a source built version Unreal Engine 4.21, released in 2018. (Source article, Source article 2) A fix for this could be migrating the game to a newer version of the engine, but as of writing this document, this is not planned.
First, try the following options:
- Make sure the game is up to date
- Verify integrity of game files
Then, apply the following workaround:
1. Open “File Explorer” (Win+E), right-click on “This PC”, and select
“Properties”
2. Select “Advanced System Settings”
3. Select “Environment Variables” in the “Advanced” tab
4. Select “New…” under “System variables”
5. Input the text below and select “OK”
6. Variable name: OPENSSL_ia32cap
7. Variable value: ~0x200000200000000
8. Confirm that the variable has been added successfully, then select
“OK”
