Divine Frequency Engine: GZDoom, Saves, Defender, Proton

What engine does Divine Frequency use?

Divine Frequency from Abraxaes is built on GZDoom / UZDoom, per GamingOnLinux (2026-10-27) and Bridgeburner’s 2023 demo patch notes on GZDoom lineage. Expect Doom-engine-style saves and performance quirks—not Unity or Unreal. For stutter workarounds, see performance and stutter fixes.

Do saves break when the game updates?

GZDoom save incompatibility when core game files change is documented in the 2023 demo patch—you may need to restart mid-playthrough after an update that replaces core files. That rule comes from Demo-era patch notes; Early Access updates may follow the same pattern, but no EA-specific save bulletin was in the sources checked on 2026-10-28. Back up saves before major patches if you care about a run in progress, and watch Steam announcements for Abraxaes posts.

Why might Windows Defender block DivineFrequency.exe?

The itch.io page states Windows Defender may false-flag DivineFrequency.exe. Treat that as a known false-positive risk on the official itch listing, not as instructions to disable security software blindly. Download from Steam or itch.io links Abraxaes controls (see store and itch.io project page). If performance issues appear only after quarantine, fix Defender exclusions only after you trust the file hash and source.

Can I run Divine Frequency on Linux with Proton?

Steam lists Windows only—no native macOS or Linux build in the store snapshot we checked. GamingOnLinux reports the Windows build via Proton 11 on Steam “plays just fine” in their test—single media session, not an official Linux port or Steam Deck verification. For official minimum and recommended specs (OpenGL 3.3 minimum GPU, OpenGL 4.0 or Vulkan recommended), use system requirements and Proton rather than guessing from engine name alone.

Is the game open source or moddable?

itch.io shows a GNU GPL v3.0 license label on project files, with no public source repository URL on that page as of 2026-10-28. Our GitHub search did not find an Abraxaes-published source tree to link. The reviewed sources do not document an official modding path—no install guide for mods, unpacking, or WAD editing appears in the facts we cite. If mod support matters for your purchase, see is Divine Frequency worth it? and wait for developer statements instead of assuming GZDoom-era mod tools apply to EA.
