Set Hardware Acceleration Level

From Wiki

Jump to: navigation, search

Here is a vbscript that will allow you to set the primary display's hardware acceleration automatically on Windows. To set the level edit the value uValue to the level required: 2000/XP: 0 being full acceleration and 5 being no acceleration Windows Server 2003: 5 being full acceleration and 0 being no acceleration

If you need to set it for other monitor outputs then change the sValue to be \Device\VideoX (X being the display number) To find this value browse in regedit to HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\VIDEO

NOTE: After running the script you may need to reboot for the changes to take effect. 


Const HKEY_LOCAL_MACHINE = &H80000002
 
sComputer = "."
sMethod = "GetStringValue"
hTree = HKEY_LOCAL_MACHINE
sKey = "HARDWARE\DEVICEMAP\VIDEO"
sValue = "\Device\Video0"
 
Set oRegistry = GetObject("winmgmts:{impersonationLevel=impersonate}//" & sComputer & "/root/default:StdRegProv")
 
Set oMethod = oRegistry.Methods_(sMethod)
Set oInParam = oMethod.inParameters.SpawnInstance_()
 
oInParam.hDefKey = hTree
oInParam.sSubKeyName = sKey
oInParam.sValueName = sValue
 
Set oOutParam = oRegistry.ExecMethod_(sMethod, oInParam)
strParse = oOutParam.Properties_("sValue")
 
sMethod = "SetDWordValue"
hTree = HKEY_LOCAL_MACHINE
sKey = Replace(strParse, "\Registry\Machine\", "",1,Len(sKey),1)
'replace command must run case insensitive to work on different hardware
sValueName = "Acceleration.Level"
'* In Windows XP Change the uValue value for Accelleration.Level from 0 (FULL) to 5 (none)
uValue = 1
 
Set oRegistry = GetObject("winmgmts:{impersonationLevel=impersonate}//" & sComputer & "/root/default:StdRegProv")
Set oMethod = oRegistry.Methods_(sMethod)
Set oInParam = oMethod.inParameters.SpawnInstance_()
 
oInParam.hDefKey = hTree
oInParam.sSubKeyName = sKey
oInParam.sValueName = sValueName
