The new version 1.03 for Windows/Linux has an optional command line parameter that can be used to tune screen refresh and GPU load.

This option isn't needed or supported for NVIDIA Pascal or newer GPUs on Windows 10.
Windows 10 uses different GPU scheduling on Pascal+ GPUs making this feature unnecessary.

The -ws # command line option is for the user to adjust GPU load higher for faster computation or lower for better screen refresh rate. Usage: -ws 10 for default, -ws 1 for lowest GPU load, -ws 100 for highest GPU load. Worksize can be any number from 1 to 100.

You will need to make an app_config.xml in the BOINC\projects\www.primegrid.com directory with the following for Nvidia:

<app_config> <app_version> <app_name>ww</app_name> <plan_class>OCL_cuda_WW</plan_class> <cmdline>-ws 10</cmdline> </app_version> </app_config>


Or for AMD:
<app_config> <app_version> <app_name>ww</app_name> <plan_class>opencl_ati_WW</plan_class> <cmdline>-ws 10</cmdline> </app_version> </app_config>

app_config example is not correct. "app" block must either not present at all (then it's parameters will be not overridden), either have all it's parameters specified. So it's much simpler to write just

<app_config> <app_version> <app_name>ww</app_name> <plan_class>opencl_ati_WW</plan_class> <cmdline>-ws 10</cmdline> </app_version> </app_config>
