Problem 3: Poor performance / low frame rate (FPS)

Power saving mode Windows:

Especially mobile devices (laptops) should be connected to the power supply, other-wise the performance can be reduced.

Therefore, please also check in the Windows 10 info window (action window in the taskbar) as well as in the Windows power saving options of the control panel whether the computer is running in energy-saving mode.

Graphics card driver and power saving mode:

Please check if your graphics card drivers are up to date. Then set the operating mode to Performance in the software of your graphics card.

Select the correct graphics card:

If you have more than one graphics card, for example an integrated one on the CPU and a dedicated graphics card with better performance, please check that the correct card is selected in the settings (Current.xml or CurrentVR.xml). The graphics card currently used by the VR-Edition is also displayed in the title of the Desktop Client (see screenshot in chapter Opening a CAD model in VR).

Here is a way to proceed:

▪Start the 3DViewStation Desktop.

▪Go to the settings (bottom left).

▪Enter the term "Display adapter" in the search field.

▪Set the graphics card with the highest performance.

▪Save the settings using the small floppy disk symbol.

If you have not created separate settings for VR (CurrentVR.xml), the graphics card is now activated and you can exit 3DViewStation Desktop. However, if you are using a CurrentVR.xml, this setting must still be transferred.

▪Open the Help tab and activate the User button.

▪Open the Settings folder and the included Current.xml (desktop settings) with an editor like Notepad++.

▪Look for the line <GraphicsAdapterToUse>0</GraphicsAdapterToUse> and remember the value – here 0.

▪Open the file CurrentVR.xml and store the same value here in the matching location (<GraphicsAdapterToUse>).

▪Save the change.

Problem 4: Poor tracking

Please check your hardware installation as described in chapter VR Hardware.
