Add an Exception to Windows Firewall

Rainbow Six Siege’s frequent crashes may be caused by network problems. Windows Firewalls can cause this problem by blocking your game’s internet traffic.

3. Select one of the options on the left hand side of the window that opens. Then, click on Allow an app or feature through Windows Defender Firewall.

4. In the following window, you will see a list of programs that can bypass the Firewall. To change the settings, click on Change settings in the upper right corner.

5. Next, click Allow another app.

6. Choose Browse from here.

7. To continue, you must find and select the .exe file for your game. Browse to the game file folder to do so.

Navigate to the folder where you have installed your Steam games. Follow these steps:

steamapps > common > Tom Clancy’s Rainbow Six Siege

8. Choose RainbowSix.exe from this list.

9. On the previous window, click Add once you have returned.

You should now be able to play Rainbow Six Siege without crashing due to network issues with your PC.

2. Select the first option.

Restart your PC when you have updated your device drivers. If Rainbow Six Siege was crashing for you while playing on PC, this should fix the problem. This applies to both start-up and in-game crashes.

Verify the Integrity of Game Files

The main cause of regular Rainbow Six Siege PC crashes is likely to be corrupted game files. However, both Steam and Ubisoft Connect versions of the game have built-in tools to repair these files.

Steam

1. Launch Steam on your computer. Click on the Library tab.

2. Select  Rainbow Six Siege from your games list.

3. Click right on the game. Choose Properties.

3. Click on the icon for the game. You’ll be taken to another page.

4. From the left-hand list, select Properties.

5. Select Verify Files from the Local Files section.

As a result, Ubisoft Connect/Steam will check your game files. A redownload will be performed for any files found to be corrupt or missing. Rainbow Six Siege’s game files are large and may take a while to check. Once it is complete, you shouldn’t experience any more crashes on your PC.

Disabling the Cloud Save Feature

Activating cloud save in Uplay is also a major cause of the Rainbow Six Siege Crashing issue. It has been confirmed by several users that if you activate the cloud save, there is a possibility of having this issue. Here’s how to disable it.

1. Run the U-play client and click the menu. Select Settings.

2. Go to the General tab, where you will find an option for Enable Cloud Save Synchronization. Make sure it is not checked.

3. Ensure that the Enable in-game overlay box for supported games is also unchecked.

4. Save your changes when done. Restart the game.

Limit the Frame Rate

Trying limiting your framerate in Rainbow Six Siege may resolve your issue with the game crashing on your PC if all else fails. Increased CPU usage can result from excessive framerates. However, most games do not experience this issue. There have been reports of crashing in Rainbow Six Siege. You should, therefore, limit your frame rate to a value slightly lower than the maximum frame rate you can achieve in the game. 

You should limit your framerate to at most 140 frames per second if your system is able to push 160 frames per second. To do this, follow these steps.

1. Launch the Windows File Explorer. Navigate to Documents.

2. Select My Games from here. Next, select Rainbow Six – Siege.

3. Double-click the long, alphanumeric folder.

4. Use a text editor like Notepad to open the GameSettings.ini file.

5. Find the FPSLimit setting in the DISPLAY settings. Select the framerate you want. In this example, if you decide that your maximum FPS will be 140, make sure that FPSLimit=140 is displayed in your text line.

Performance may be slightly affected by this. It will, however, make the experience much smoother. Moreover, the performance setback is insignificant if you choose a framerate limit that is appropriate. The majority of players won’t notice the difference.
