1. Are you using the right internet program (browser)?

GameDuell optimizes its services for the most common Internet programs. If you are having problems using GameDuell, it may be helpful in certain cases to use a different browser. If you are experiencing technical problems, you can narrow down the problem further by first testing whether the problem also occurs when using a different browser.

You can download and install various browsers for free on the Internet.

Please always make sure that you have installed the latest version of the browser of your choice.

A selection of the most common browsers:

• Google Chrome
• Mozilla Firefox
• Microsoft Edge
• Opera Browser

For gamers with older computers or limited RAM, we particularly recommend the Opera browser.

2. Are there outdated internet files on your computer?

Please regularly delete the temporary internet files (cache and cookies) in your internet program (browser) and then restart the browser. When doing so, please make sure to select "all", "entire period" or similar in the period setting rather than "only the last hour".

Most problems can be solved quickly by deleting cache and cookies.

Instructions for the most common Internet programs can be found here:

"Settings" > "Safari" > "Delete data and cookies".

"Advanced" > "Website Data " > "Delete all website data".

3) Check if your browser hardware acceleration settings are optimal 

Turning hardware acceleration on or off in your browser can also solve technical problems. We recommend testing both settings once here, as this approach can have different effects depending on the technical requirements.

Google Chrome

• Click the three dots at the top right of the browser.
• Click on "Settings".
• Under “System” you will find the setting "Use hardware acceleration if available".
• Set or remove the check mark under this item.
•  Restart the browser and test whether the change has a positive effect on your gaming experience.

Firefox

•  Click on the three horizontal lines on the right edge of the browser.
• Click on "General".
• Under "Performance" you will find the "Use recommended performance settings" setting - uncheck it here.
• Now you will see the setting "Use hardware acceleration when available".
• Set the checkmark to activate this setting.
• Restart the browser and test whether the change has a positive effect on your gaming experience.

4. Are you using an outdated operating system?

Windows

Microsoft has stopped supporting Windows XP and Windows 7, and will soon stop supporting Windows 8 as well. No new security issues will be addressed, which can result in high risk when using outdated operating systems online. We therefore strongly advise you to switch to a newer version - ideally Windows 10.

You can find more information directly here at Microsoft.

Mac OS X

Always keep your Mac OS X up to date. A free update is available to users starting with version 10.6.8 here. This ensures that components, such as the Safari browser, are always technically up-to-date.

5. Do you play using a wireless internet connection?

Experience has shown that you may experience frequent disconnections when trying to play our live games via a wireless internet connection. Since the connection strength can vary more often with wireless connections, please use a fixed Internet connection via cable if possible.

Furthermore, please check the WLAN channel that your router works with. This can often solve existing connection problems in your WLAN network.

You can find explanations on this topic here.

Connections via LTE or UMTS are not recommended due to lack of signal stability.
