# Why need to wait a long time to open a D5 scene?

Since some files need to be compiled when starting D5 for the first time, the first loading of the D5 scene after updating the driver or installing D5 will be slightly slower; the second loading will be much faster.

{% hint style="warning" %}
Due to compilation reasons, if the windows system is named Chinese and other non-English name each time you open D5 may need to wait a long time (which is related to windows system dx12), it is recommended to create a new English user account and use this account to log in windows and run the software.
{% endhint %}
