AppHints

Application Specific Settings (Apphints)

The PowerVR control panel (accessible through Display Properties) allows the end-user to set/modify PowerVR settings on a per application basis. These PowerVR AppHints may help to enhance compatibility and/or performance for a given 3D application.

One example includes the translucency sorting in the PowerVR driver. By default this is enabled, but if the application sends pre-sorted translucent polygons to PowerVR it is possible to save time by disabling the translucency sorting in the drivers. This can be done in the PowerVR control panel which will effectively create an AppHint in the registry with the following entries in

[HKEY_LOCAL_MACHINE\SOFTWARE\PowerVR\PCX1&2\App hints\application.exe]: [HKEY_LOCAL_MACHINE\SOFTWARE\PowerVR\PCX1&2\App hints\application.exe]:

SglTransSort = 1
DisableNewPassPerTri = 1
SglTransSort = 1
DisableNewPassPerTri = 1

PVRCreateAppHint Includes .c and .h files containing the function PVRCreateAppHint. This function can be used as PVRCreateAppHint(Exe name,String name,String Value); For the above example this would look like PVRCreateAppHint("mygame.exe", "SglTransSort", "1"); PVRCreateAppHint("mygame.exe", "DisableNewPassPerTri", "1"); Click here to download the PVRCreateAppHint files [3 KB] This also includes an example application file Apptest.c using this function and the corresponding Apphint.reg file.
