Diablo 3 crashing
1. Make sure that your drivers are up to date
Diablo 3 crashes can be caused by outdated video driver, therefore if you’re experiencing any issues with Diablo 3, we strongly urge you to update your drivers first.
Many users reported that downloading the latest drivers for their graphics card fixed the crashing issues, so make sure you try that.
We recommend TweakBit Driver Updater (100% safe and tested by us) to automatically download all the outdated drivers on your PC. This tool will prevent file loss and help you to avoid permanent damage to your PC caused by downloading and installing the wrong driver versions.

2. Set BattleNet and Diablo 3 to power-saving mode
Few users claim that they solved the crashing issues with Diablo 3 by setting both the game and the BattleNet client to run in power saving mode from Catalyst Control Center.

EVGA Precision X is a useful overclocking tool for your graphics card that can help you boost your PC performance.
If you want to know more about this tool and overclocking in general, we wrote an article about the best overclocking software for Windows 10, so you might want to have a look at it.
Although overclocking tools might boost your PC performance, sometimes these tools can cause instability issues with certain games, such as Diablo 3 in this particular case.
In order to fix Diablo 3 crashes, users are strongly advising to turn off EVGA Precision X while running Diablo 3. If you have to run Precision X, make sure you are using the latest version, but if the latest version is giving you problems, try using the older version instead.
Diablo 3 freezing
1. Lower your graphic settings
In some cases, Diablo 3 freezing can be caused by your graphics settings, so in order to fix it, you’ll need to lower the texture quality.
Users reported that lowering texture quality to Low fixes the issue for them. Even though your game won’t look the best with low-resolution textures, it should run without any freezing.

2. Change Timeout Detection and Recovery values
Timeout Detection and Recovery, or TDR for short, is an option that is in charge of your graphic card driver. This option comes with its own value, and if for some reason your graphics card doesn’t respond within the set time frame, the graphic card driver resets.
This can sometimes cause Diablo 3 to freeze, so let’s try to change TDR value. To do that, follow these steps:

- Enter 8 as the value and click OK to save changes.
- Close Registry Editor and restart your computer in order to apply changes.
3. Change Power Options
Diablo 3 freezes can be caused by your power settings, so in order to fix these issues, we advise you to change these settings. To do that, simply follow these instructions:
- Press Windows Key + S and enter Power Options. Select Power Options from the menu.
- Once the Power Options window opens, locate your current power plan and click on Change plan settings.
- Click on Change advanced power settings.

- Expand Link State Power Management and set it to Off.
- Click Apply and OK to save changes.
