Poor player performance is often caused by outdated graphics drivers and hardware acceleration in de browser. Browser manufacturers try to improve browser performance by using the capabilities of the graphics card to do render frames faster. This method is called Hardware Acceleration. But browsers depend on graphic drivers on your PC to be up to date. When the drivers are not up to date, the effect might counterproductive.


In your browser you may experience choppy playback of video when hardware acceleration doesn't work as it should. The first step to improve is to update you graphics drivers of you PC to the latest version. This only works if you have an Intel, nVidia or AMD GPU. Find and install the latest driver on the PC manufacturer website.


In release 5.3 we introduced Simple Mode, when the browser detects significant frame drops it switches to Simple Mode. In this mode the Scenarios will be disabled and less GPU performance is needed.
You can also enable / disable Simple Mode via the button bar.



Alternatively you can disable hardware acceleration in the browser and force CPU usage. The method to do so differs per browser:
