After Patch 1.13, many players reported a new type of stuttering that was not present in earlier versions of Crimson Desert. This issue is specifically related to Variable Refresh Rate (VRR) technology, which includes AMD FreeSync, NVIDIA G-Sync, and HDMI VRR. The stutter manifests as periodic frame hitches that occur every few seconds, making the game feel choppy even when the frame rate counter shows a stable number.
The root cause is a desynchronization between the GPU's frame delivery and the display's refresh rate. Patch 1.13 introduced changes to the rendering pipeline that altered how frames are presented to the display. When VRR is active, the display adjusts its refresh rate to match the GPU output, but the new frame presentation timing in 1.13 creates micro-gaps that VRR interprets as stutter.
Several factors compound the issue:
- Stale shader cache - The old shader cache from pre-1.13 patches conflicts with the new rendering pipeline
- VRR range mismatch - Displays with narrow VRR ranges are more susceptible to the desync
- Frame generation conflicts - Frame generation technologies like DLSS 3 Frame Generation can amplify the stutter
- Driver version - Some GPU driver versions handle the new frame timing differently
Fortunately, the fix is relatively straightforward. Clearing the shader cache and adjusting a few graphics settings resolves the issue for the vast majority of players.

How to Clear the Shader Cache (Step by Step)
Clearing the shader cache is the single most effective fix for VRR stutter after Patch 1.13. The shader cache stores compiled shaders from previous sessions, and when the rendering pipeline changes in an update, stale cached shaders can cause conflicts and stuttering.
Step 1: Close Crimson Desert completely. Make sure the game is not running in the background. Check your system tray and taskbar for any residual processes.
Step 2: Navigate to the shader cache location. The shader cache is stored in your LocalAppData folder. Open File Explorer and enter the following path in the address bar:
%LOCALAPPDATA%\CrimsonDesert\Saved\ShaderCache
Alternatively, navigate manually to C:\Users\[YourUsername]\AppData\Local\CrimsonDesert\Saved\ShaderCache. Note that the AppData folder is hidden by default, so you may need to enable hidden items in the View tab.
Step 3: Delete the entire ShaderCache folder. Select the folder and press Delete. This will remove all cached shaders. Do not worry about deleting important files; the game will regenerate the cache on next launch.
Step 4: Verify game files in Steam. Right-click Crimson Desert in your Steam library, select Properties > Installed Files > Verify Integrity of Game Files. This ensures no game files were corrupted during the patch update.
Step 5: Launch the game. The first launch after clearing the cache may take longer as shaders recompile. You may experience brief stutter during the first few minutes of gameplay as the cache rebuilds, but this should resolve quickly and the VRR stutter should be gone.
Best Graphics Settings to Reduce Stutter
In addition to clearing the shader cache, adjusting your graphics settings can further reduce or eliminate stutter. The following settings have been tested and confirmed to improve frame consistency on a wide range of hardware configurations.
| Setting | Recommended Value | Reason |
|---|---|---|
| V-Sync | Off (use VRR instead) | V-Sync conflicts with VRR and adds input lag |
| Frame Rate Cap | Match monitor refresh rate | Prevents frame spikes that trigger stutter |
| DLSS / FSR | Quality or Balanced | Reduces GPU load for more consistent frame times |
| Frame Generation | Off | Conflicts with VRR and amplifies stutter |
| Shadow Quality | Medium | High shadows cause frame time spikes in dense areas |
| Volumetric Clouds | Medium or Low | Major source of frame time variance |
| Shader Quality | Medium | Reduces shader compilation stutter |
The most impactful single change is disabling Frame Generation if you have it enabled. While Frame Generation can boost average frame rates, it introduces frame pacing inconsistencies that VRR cannot smooth out, resulting in perceived stutter even when the frame rate counter looks stable.
If stutter persists after these changes, try lowering Texture Quality and Draw Distance by one tier each. These settings affect VRAM usage and can cause stutter if your GPU runs out of video memory, triggering texture streaming.
VRR and G-Sync Compatibility Settings
Properly configuring VRR at the system level is the final step in eliminating stutter. Both NVIDIA G-Sync and AMD FreeSync need to be configured correctly to work with Crimson Desert's rendering pipeline.
For NVIDIA G-Sync users:
- Open NVIDIA Control Panel > Set up G-Sync > Enable G-Sync for full screen mode
- Go to Manage 3D Settings > Program Settings > select Crimson Desert
- Set Vertical sync to Off (let G-Sync handle synchronization)
- Set Low Latency Mode to Ultra for reduced input lag
- Set Max Frame Rate to your monitor's refresh rate (e.g., 144)
For AMD FreeSync users:
- Open AMD Adrenalin > Gaming > Display > Enable FreeSync
- Set the FreeSync range to match your monitor's supported range
- Disable Enhanced Sync, as it can conflict with FreeSync
- Set Radeon Anti-Lag to Enabled
Windows Graphics Settings: Open Windows Settings > System > Display > Graphics, find Crimson Desert, and set it to High Performance. Then click Change Default Graphics Settings and ensure that Variable Refresh Rate is toggled On.
If stutter persists after all of these changes, try disabling VRR entirely as a last resort. While this removes the benefits of adaptive sync, some displays simply do not handle Crimson Desert's frame timing well with VRR enabled. Playing with a fixed refresh rate and a frame rate cap can provide a stutter-free experience on problematic setups.
