March 2026 PC Technical Issues & Fixes

Since launch on February 27, 2026, Resident Evil 9: Requiem has had numerous PC-specific technical problems. Here’s a comprehensive breakdown of every known issue, error codes, and how to fix them.

Critical Launch Issues

1. Fatal D3D Error (DirectX 12 Crash)

Issue: Game crashes with “Fatal D3D” error message, often during gameplay or cutscenes.

Fixes:

1. Update GPU Drivers - Install latest NVIDIA/AMD drivers (avoid NVIDIA 595.59, use 591.86 instead)
2. Disable Ray Tracing - Turn off RT or Path Tracing in graphics settings
3. Lower VRAM Usage - Reduce Texture Quality if VRAM exceeds 95%
4. Switch to DirectX 11 - Add -d3d11 to Steam launch options (if supported)
5. Disable Overclocking - Return GPU/CPU to stock speeds

Why it happens: RE Engine’s aggressive memory management conflicts with certain DirectX 12 implementations, especially when VRAM limits are breached.

Source: GameRant, XMODhub

2. Black Screen on Startup

Issue: Game launches to black screen with no audio or UI, sometimes with cursor visible.

Fixes:

1. Wait 10 minutes - Shader compilation may be running in background
2. Force Windowed Mode - Edit config file or use Alt+Enter
3. Set Refresh Rate to 60Hz - Temporarily in Windows Display Settings
4. Delete Config File - Navigate to steamapps/common/Resident Evil Requiem and delete config.ini
5. Disable Fullscreen Optimizations - Right-click re9.exe → Properties → Compatibility

Why it happens: RE Engine shader compilation on first boot causes heavy CPU load that appears as a freeze.

Source: XMODhub, PCGamingWiki

3. Repeated Unhandled Exception Error

Issue: Game crashes with “Unhandled Exception” error code, often related to DirectStorage.

Fixes:

1. Disable DirectStorage - Some users report success disabling this feature in BIOS
2. Verify Game Files - Steam → Properties → Installed Files → Verify integrity
3. Delete Storage Folder - Remove storage folder in game directory (forces regeneration)
4. Update Windows - Ensure latest Windows 10/11 build with DirectStorage support
5. Check NVMe Drive Health - Use CrystalDiskInfo to verify SSD functionality

Why it happens: RE Engine’s DirectStorage implementation conflicts with certain NVMe drivers or corrupted game files.

Source: Reddit r/residentevil, YouTube

4. Crash on Startup with REFramework

Issue: Game crashes immediately when REFramework mod (dinput8.dll) is installed.

Fixes:

1. Remove REFramework - Delete dinput8.dll from game directory
2. Wait for Update - REFramework may not support latest game version (1.110.000+)
3. Use Nightly Build - Download REFramework nightly with bdshemu linker fix
4. Check Mod Compatibility - Verify all mods are updated for current patch

Why it happens: REFramework hooks conflict with game’s anti-tamper or updated executable.

Source: GitHub praydog/REFramework #1619, Nexus Mods

Performance Issues

5. Severe Stuttering and Frame Time Spikes

Issue: Micro-stutters when navigating rooms, cutscene transitions, or specific areas.

Fixes:

1. Lower Graphics Settings:
   • Texture Quality: Low or Normal
   • Frame Generation: OFF
   • Ray Tracing: OFF
   • Mesh Quality: Low
   • Volumetric Fog Resolution: Lowest
   • Ambient Occlusion: Off or Low
2. Disable Resizable BAR - BIOS setting (especially for AMD users)
3. Update GPU Drivers - Roll back to NVIDIA 591.86 if using 595.59
4. Install on SSD - Required for proper asset streaming
5. Clear Shader Cache - Delete shader cache files, restart PC
6. Close Background Apps - Disable overlays, recording software, security scans

Why it happens: Frame time spikes caused by storage streaming, shader cache issues, or graphics settings exceeding GPU capacity.

6. Path Tracing Performance Issues

Issue: Unplayable framerates when Path Tracing is enabled, even on high-end hardware.

Fixes:

1. Switch to RT High/Normal - Path Tracing to RT High delivers up to 350% performance boost
2. Enable DLSS/FSR - Use Quality or Balanced mode for upscaling
3. Reduce RT Quality - Lower from Ultra to High or Normal
4. Disable for Competitive Play - Turn off entirely for smoother gameplay

Performance Impact (RTX 4070 Ti Super):

• Path Tracing: ~30-40 FPS
• RT High: ~60-70 FPS
• RT Normal: ~80-90 FPS
• RT Off: ~120+ FPS

Source: Digital Foundry, Screen Rant

7. Shader Compilation Stutter (First Launch)

Issue: Game appears frozen on first boot with black screen for 5-15 minutes.

Fix:

1. Wait Patiently - Do NOT force close; shader compilation is running
2. Watch for Progress - Some systems show subtle loading indicators
3. Subsequent Launches - Issue only occurs on first boot or after driver updates

Why it happens: RE Engine compiles shaders on first launch, causing heavy CPU load and temporary freeze.

Source: XMODhub, PCGamingWiki

Audio Issues

8. Complete Silence / No Sound

Issue: Game launches but produces no audio whatsoever.

Fixes:

1. Change Windows Sample Rate:
   • Press Windows key → Type “Change system sounds”
   • Playback tab → Right-click active device → Properties
   • Advanced tab → Set Default Format to 24-bit, 48000 Hz (Studio Quality)
   • Click Apply and restart game
2. Verify Game Files - Missing audio bank files common with packet loss during download
3. Update Audio Drivers - Download latest Realtek/motherboard drivers (not Windows Update defaults)

Why it happens: RE Engine conflicts with audio formats exceeding 24-bit/48000 Hz, causing game to mute itself.

Source: XMODhub

9. Audio Stuttering and Desync

Issue: Sound effects stutter during combat; cutscene dialogue out of sync with lip movements.

Fixes:

1. Disable Spatial Sound:
   • Right-click speaker icon → Sound settings
   • Output device → Spatial sound → Set to “Off” (not Windows Sonic or Dolby Atmos)
   • Toggle off “Enhance audio”
2. Switch to Stereo Output:
   • Sound Control Panel → Select playback device → Configure
   • Audio channels → Select “Stereo” (not 5.1/7.1 surround)
3. Change In-Game Dynamic Range:
   • Options → Audio → Dynamic Range
   • Set to “Headphones” or “Small” (not “Home Cinema” or “Large”)
4. Disable Peripheral Software:
   • Turn off Razer Synapse, Logitech G Hub, Corsair iCUE virtual audio drivers
   • Disable “Virtual Surround” or “Audio Enhancement” in headset software

Why it happens: Spatial audio enhancements conflict with RE Engine’s native binaural processing; surround sound output to stereo headset drops center channel dialogue.

Source: XMODhub

10. Missing Cutscene Dialogue

Issue: Characters move mouths but no voices are heard during cutscenes; background music and SFX work fine.

Fixes:

1. Force Stereo Mode (see Fix #9 above)
2. Change Dynamic Range to Headphones (see Fix #9 above)
3. Disable Windows Sonic/Dolby Atmos (see Fix #9 above)
4. Check Audio Output Device - Ensure not routing to monitor/TV HDMI audio

Why it happens: 5.1/7.1 surround output to stereo headset drops center channel where dialogue is mixed.

Source: XMODhub

Visual Issues

11. Visual Bugs with Certain GPU Drivers

Issue: Graphical artifacts, texture flickering, or incorrect lighting with specific driver versions.

Fixes:

1. Update to Latest Drivers - March 27, 2026 patch fixed visual bugs on some GPUs
2. Roll Back Problematic Drivers - NVIDIA 595.59 caused issues; use 591.86
3. Disable Frame Generation - Some users report visual glitches with FG enabled
4. Verify Game Files - Corrupted texture files may cause visual issues

Source: Capcom Official, PCGamingWiki

12. Settings Changes Require Restart

Issue: Changing Texture Quality, RT Quality, or Strand Hair System requires full game restart to apply.

Workaround:

• Plan settings changes before starting gameplay session
• Use preset configurations to minimize restarts
• Accept as engine limitation (not fixable by users)

Why it happens: RE Engine limitation - certain settings require engine reload to apply properly.
