> Vicon software uses the [Intel](https://vicon-help.atlassian.net/wiki/spaces/Connect/pages/1613600/Improving+system+performance+on+AMD+CPUs#TMAcknowledgement)<sup>[®](https://vicon-help.atlassian.net/wiki/spaces/Connect/pages/1613600/Improving+system+performance+on+AMD+CPUs#TMAcknowledgement)</sup> MKL library for optimized mathematical operations. You may be able to improve performance on AMD CPUs that support the AVX2 instruction set by setting an environment variable.
> 
> 
> **To change the required setting:**
> 
> 
> 1. Change the relevant environment variable using your preferred method:
>   - To set the environment variable for the current user only:
>     - In the Windows **System Properties** dialog box, click **Environment Variables**.
>     - In the **Environment Variables** editor, in the **User variables for ***<username>* section, click **New**.
>     - In the **New User Variables** dialog box, in the **Variable name** field, enter `MKL_DEBUG_CPU_TYPE` and in the **Variable value** field, enter `5`.
>   - To set the variable for all users:
>     - Ensure you have Admin privileges.
>     - From the command line enter the following command:
>       `setx MKL_DEBUG_CPU_TYPE 5 /m`
> 2. Restart your Vicon application.
