What Is Doom: The Dark Ages?
Doom: The Dark Ages is the 2025 entry in the mainline Doom series, developed by id Software and published by Bethesda. It is a prequel to 2016's Doom and Doom Eternal, set in a dark medieval era where the Doom Slayer battles demonic forces using medieval-era weaponry alongside futuristic firepower. Released on May 15, 2025 for PC (Steam, Xbox App/Game Pass), Xbox Series X|S, and PlayStation 5, it was a Day 1 Game Pass title on PC.
The game runs on id Tech 8 — a new iteration of id Software's proprietary engine that brings forward-looking graphics features including path-traced global illumination, a full ray-traced lighting pipeline, and DLSS 4 Multi Frame Generation support on Nvidia hardware.
Unlike Doom Eternal's aerial emphasis, The Dark Ages is built around grounded, aggressive combat. The Shield Saw is the new defensive tool: a circular saw blade you can parry demon attacks with and hurl as a projectile. Melee is central — the game pushes you into close-quarters fights that reward timing and aggression, not retreating.
System Requirements
| Tier | CPU | GPU | RAM | Storage |
|---|---|---|---|---|
| Minimum (1080p/60) | Intel Core i7-9700K / AMD Ryzen 7 3700X | Nvidia RTX 2060 / AMD RX 6600 | 16 GB DDR4 | 100 GB NVMe SSD |
| Recommended (1440p/60) | Intel Core i7-13700K / AMD Ryzen 7 7700X | Nvidia RTX 4070 / AMD RX 7800 XT | 32 GB DDR5 | 100 GB NVMe SSD |
| Ultra (4K/60 + RT) | Intel Core i9-14900K / AMD Ryzen 9 7950X | Nvidia RTX 4090 / AMD RX 7900 XTX | 32 GB DDR5 | 100 GB NVMe SSD |
NVMe SSD is required. The game uses id's Mega-Texture streaming system; a hard drive or SATA SSD will cause visible texture pop-in and stuttering.
Best PC Settings for Performance
id Tech 8 is an extremely well-optimised engine — the same lineage that made Doom Eternal run at 200+ fps on mid-range hardware. The Dark Ages continues that tradition. Most players on recommended-tier hardware can run at maximum settings. The tips below are for players pushing framerates or playing on slightly older hardware.
Resolution and Upscaling
Upscaling is the best tool you have:
- Nvidia RTX — use DLSS 4 Quality mode. On an RTX 4070, DLSS 4 Quality at 1440p delivers near-native image quality while recovering 20–30% performance headroom.
- AMD RDNA — FSR 4 is supported. FSR 4 Quality mode performs similarly to DLSS 4 Quality on RDNA 4 cards.
- Intel Arc — XeSS is supported.
If you are at 1080p with a mid-range card and already hitting your target framerate, you do not need upscaling at all. id Tech 8 is efficient enough that native 1080p Ultra at 60fps is achievable on an RTX 3070 class card.
Ray Tracing Tiers
id Tech 8's lighting pipeline is ray-traced by default in the sense that global illumination uses hardware ray tracing. The settings panel gives you control over how much:
| RT Setting | Performance Cost | Visual Gain |
|---|---|---|
| RT Off | Baseline | Baked lighting (still looks good) |
| RT Medium | ~15% | Path-traced shadows, improved GI |
| RT High | ~30% | Full path tracing, contact shadows |
| RT Ultra | ~50%+ | Highest quality, reference-grade lighting |
Recommendation: RT Medium is the sweet spot for most players. The jump from Off to Medium is clearly visible; Medium to High is subtle in motion; High to Ultra is almost imperceptible at 60fps.
On an RTX 3080 at 1440p: RT Medium at native resolution holds 60fps comfortably. Add DLSS 4 Quality and you are at 80–90fps.
Other Performance Settings
| Setting | Recommended Value | Notes |
|---|---|---|
| Shadow Quality | High (not Ultra) | Ultra shadows cost 8–12% for minor gain |
| Texture Quality | Ultra | VRAM-heavy; drop to High if VRAM <8 GB |
| Ambient Occlusion | HBAO | Path traced RT AO only needed at RT Ultra |
| Anti-Aliasing | Off (use DLSS/FSR instead) | TAA has blur; upscalers do it better |
| Motion Blur | Off | Matter of preference; minor performance gain |
| Depth of Field | Medium | Heavy at Ultra; doesn't affect gameplay |
| Field of View | 100–110° | EmuDesk default recommendation for PC |
| Vsync | Off | Use NVIDIA Frame Generation / Reflex for latency |
Frame Generation (Nvidia RTX 40 / AMD RX 7000)
The game supports DLSS 4 Multi Frame Generation (Nvidia RTX 40-series) and FSR 4 Frame Generation (AMD RX 7000-series). Frame generation adds generated frames between rendered frames, significantly boosting displayed fps.
Important: Frame Generation raises your perceived framerate but also adds latency. For Doom, where parry timing on Shield Saw attacks matters, keep base framerate above 60fps before enabling Frame Generation. Do not rely on frame generation to bring a 30fps base up to playable — the latency will hurt your parry windows.
Fixing Common PC Issues
Shader Compilation Stutters
id Tech 8 pre-compiles shaders on first launch. You will see "Compiling Shaders" with a progress bar when you first start the game. This process takes 5–15 minutes depending on your hardware. Do not skip it or quit during compilation — if you do, you will stutter for the first 30 minutes of gameplay as shaders compile on-the-fly.
Fix: Let it complete fully on first launch. If you already skipped it: Settings → Video → Shader Cache → Rebuild.
Black Screen or Crash at Launch
Common on AMD GPUs when using DirectX 12 mode:
- In Steam: right-click the game → Properties → Launch Options → add
-dx11 - DirectX 11 mode trades a small performance penalty for stability on AMD Polaris/Navi.
- For RDNA 3/4, try DirectX 12 again after updating to the latest AMD driver.
Very Low Framerate Despite Good Hardware
Check Windows power plan: open Control Panel → Power Options → set to High Performance or Balanced (never Power Saver on a desktop). On laptops, ensure you are plugged in and the GPU is in Performance mode in Nvidia Control Panel / AMD Software.
Also check the process priority: in Task Manager, right-click the DOOMTheDarkAges.exe process → Set Priority → High. id games respond well to this.
Game Crashes After Loading
If the game crashes specifically when loading a save or entering a new level:
- Update GPU driver to latest stable release
- Check for corrupted shader cache: delete
C:\Users\[Name]\AppData\Local\id Software\DOOM The Dark Ages\shader_cacheand rebuild - Verify game files on Steam (Properties → Local Files → Verify)
Combat System — Core Mechanics
The Dark Ages is the most weapon-focused entry in the modern Doom trilogy. Understanding a few core mechanics will make the game dramatically more enjoyable.
The Shield Saw
The Shield Saw is both your primary defensive tool and an offensive projectile. Its two uses:
- Parry: When a demon telegraphs an attack (orange glow), hold the parry button to absorb it with the Shield Saw. A perfect parry staggers the demon and fills your Blood Punch meter.
- Throw: You can hurl the Shield Saw at a demon to deal heavy damage and ricochet it to chain kills. The throw travels to the target and returns to you.
The parry timing window is generous — more like a rhythm game prompt than a frame-perfect parry. Most players find it intuitive within 30 minutes of play.
Blood Punch
Executing a parry or performing a Glory Kill fills the Blood Punch meter. Blood Punch is a heavy melee attack that staggers demons in a radius. Use it in crowds, not on single targets — it is your crowd control.
Dragon (Armoured Titan)
The Dark Ages introduces large-scale segments where you pilot the Atlan mech or ride a dragon. These segments break up the ground combat and serve as boss-fight equivalents for entire arena zones. During dragon segments:
- Prioritise the wing demons first — they deal more damage
- The dragon's fire breath has a cooldown; use it on clustered demons only
- You cannot die from most regular hits during dragon segments; focus on the aerial objective, not survival
Weapon Progression
Unlike Doom Eternal's weapon mastery system, The Dark Ages uses a simpler upgrade tree:
- Weapons gain points by using them (kill with a weapon → earn that weapon's XP)
- Spend upgrade points at any Save Point or in the pause menu
- The Super Shotgun mods remain the most impactful upgrade investment for new players (as in all modern Doom titles)
Tips and Tricks
Playing on PC, a few things that differ from the console experience:
- Uncap framerate immediately. Go to Settings → Video → Frame Rate Limit → Uncapped. id Tech 8 is designed to run at high framerates; 120+ fps is meaningfully smoother than 60 in Doom because the combat is fast.
- Keyboard shortcuts for weapon wheel: Unlike Doom Eternal, you can bind individual weapons to number keys 1–0. This is faster than the weapon wheel. Bind your most-used weapons (Combat Shotgun = 1, Super Shotgun = 2, BFG = 0).
- Photo Mode: Press F12 (or a custom bind) to enter photo mode. The game has exceptional art direction — medieval demon architecture is worth photographing.
- Difficulty: The new difficulty "Nightmare" in The Dark Ages works differently than Eternal's Nightmare. Enemies are more aggressive and parry windows are shorter. Hurt Me Plenty is the intended first-playthrough difficulty.
Should You Play with a Controller or Mouse and Keyboard?
For Doom on PC: Mouse and keyboard is significantly better for combat.
The Combat Shotgun and Railgun require precise aim for maximum efficiency. The Shield Saw throw is a leading aim shot — you throw slightly ahead of a moving target — and mouse precision makes this much easier. id Software's Doom games have historically been designed primarily around mouse aim.
If you prefer controller for the experience, the game has excellent controller support with full gyro support on PC (requires a DualSense via USB or DS4Windows for DualShock 4).
Steam vs. Game Pass (PC)
The Dark Ages is a Day 1 Game Pass title.
| Steam | Game Pass | |
|---|---|---|
| Price | Full price (~$70) | Included with Game Pass |
| Mods | Full mod support | Limited mod support (Game Pass DRM) |
| Performance | Identical | Identical |
| Save Sync | Steam Cloud | Xbox Cloud |
| Offline Play | Full offline | Requires periodic online check-in |
If you are on Game Pass PC, you may notice some mods do not install correctly — this is because Game Pass uses UWP (Universal Windows Platform), which restricts file access. Install mods manually by extracting to the game directory; some mod managers (Nexus Mod Manager, Vortex) have Game Pass support in 2025–2026 builds.
Frequently Asked Questions
Does Doom: The Dark Ages have a campaign length? The main campaign is approximately 12–16 hours on first playthrough at Hurt Me Plenty difficulty. A pacifist or explorer run that finds all secrets extends this to 18–22 hours. There is no multiplayer mode (like Doom Eternal had no BR); it is a single-player game.
Is The Dark Ages harder than Doom Eternal? Most reviewers and players found The Dark Ages easier than Doom Eternal. Eternal had a notoriously steep learning curve (ammo economy, glory kill cycling). The Dark Ages simplifies the ammo system and puts more weight on parry timing, which has a longer reaction window than Eternal's dashes and flame belch cycles.
Does it support ultrawide (21:9) monitors? Yes. The Dark Ages supports 21:9, 32:9, and up to 4K resolutions. UI elements scale correctly at all aspect ratios.
How large is the install size? Approximately 90–100 GB after full installation. A fast NVMe drive is required by the game; it will refuse to install to an HDD.
Can you play it on the Steam Deck? The Dark Ages is rated Unsupported on the Steam Deck due to its high GPU requirements. It can run on a Deck with significant quality reductions (720p, Low/Medium settings, ~30fps), but it is not the intended experience. Windows 11 on Deck with an external eGPU is the only way to approach the recommended settings.
