Rainbow Six Siege crashing issues are frequently reported by players on Reddit and elsewhere. One RSS player said this, “I’m not exactly sure if this is a software or hardware issue, but my Rainbow Six Siege has been repeatedly crashing for a while now, usually after about 1 round or 3-4 minutes of playing.” Regular in-game crashing like that can make Rainbow Six Siege quite unplayable even when the game still starts. This is how you can fix recurring Rainbow Six Siege crashing on Windows PCs.

Verify the RSS Game Files

Verifying (repairing) game files is always a recommended troubleshooting method for fixing crashing issues. This may not always work, but you can’t rule out the possibility of corrupted game files causing crashing. So, try verifying Rainbow Six Siege with the Steam or Ubisoft Connect software with which you installed the game. These Ubisoft Connect and Steam pages tell you how players can verify a game’s files.

Reduce Rainbow Six’s Graphical Settings

Some players say lowering in-game graphical settings has remedied Rainbow Six Siege crashing on their PCs. This will most likely be effective if you’ve configured high graphical settings for the game, particularly on more limited, older PCs.

  • NVIDIA Reflex Low Latency: Off
  • Latency Flash Indicator: Off
  • Overall Quality: Custom
  • Texture Quality: Low
  • Texture Filtering: Linear
  • Shading Quality: Low
  • Reflection Quality: Low
  • VFX Quality: Low

  • Zoom In-Depth: Off
  • AMD FidelityFX Super Resolution 1.0 and 2.0: Off

  7. Press the Apply and OK buttons to set all selected compatibility options.

Disable Steam Overlay and Cloud Sync Settings

Players have said they’ve discovered enabling cloud syncing can cause Rainbow Six Siege to crash. The Steam overlay is also a feature known to cause gaming issues. So, try disabling the Steam overlay and cloud sync settings.

  1. Open your Steam software.
  2. Click Steam > Settings.
  3. Next, turn off the Enable Steam Cloud option.

    The Cloud tab

  4. Turn off the Enable Steam Overlay while in-game setting on the In-Game tab.

    The In Game tab

If you’ve installed Rainbow Six Siege with Ubisoft Connect, try disabling the same options for that software. You can disable the cloud syncing for that software as instructed on this Ubisoft help page. Deselect the Enable in-game overlay option for supported games setting on the same tab as the Ubisoft could syncing option.

Apply a Clean Boot

To ensure problematic background apps aren’t causing Rainbow Six Siege to crash, try applying a clean boot. Clean booting your PC will disable all third-party background apps and services that start with Windows. Furthermore, this potential solution will free up more system resources for the game. This Microsoft page tells you how users can configure a clean boot with the Windows system tools.
