Disable Hardware Acceleration QUICKLY

nequissimus · Apr 7, 2005, 12:15 PM

Some games only run with hardware acceleration turned off. It's annoying to do this via the windows menues every time, so I'm looking for a kind of "shortcut" to disable (and reenable) hardware acceleration for both graphics and sound. It could be a tray menu, a registry hack or whatever. Just something that doesen't take me 2 minutes every time.

Can you help me, please?

You should not have to disable that, at lest I've never had to...What are your rigs specs? Sure you don't have a hardware / driver issue going on?

(Right clicking your desktop, properties, advanced, troubleshoot tab, only takes like 10 seconds max)

I'm not sure if you can turn it off for all sound... But you can turn it off for direct X by useing DXDIAG, Goto start, run, type DXDIAG hit enter click sound move the slider and save...

Thx for the help, Cowboy. I'm absolutely sure that there's nothing wrong with my hardware/drivers since to shut down the graphics and sound hardware acceleration has been recommended in several forums for the game I'm talking of (1602 A.D. by Sunflowers) and has fixed my game crash issues under WinXP.

You can turn it out for sound: Start/Settings/Control Panel/Sound and Audio Devices/Speakers/Advanced/Performance. Doing that plus the graphics setting every time I play the game and then enabling the acceleration again afterwards IS actually pretty annoying, believe me.

Any other recommendations?

Well, in the meantime I helped myself. With Regmon, I monitored all the changes that happen to the registry when sound/graphics hardware acceleration is disabled. Then, I created two *.reg files, one to disalbe and another to enable hardware acceleration. Although they may differ on other systems, I'm posting them here so if anyone wants to create his own reg-files he has a clue on which values to change:

Disable hardware acceleration:

Code:

[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Hardware Profiles\0001\System\CurrentControlSet\Enum\PCI\VEN_8086&DEV_2485&SUBSYS_00201025&REV_02\3&61AAA01&0&FD\DirectSound\Mixer Defaults]
"Acceleration"=dword:0000000f

[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Hardware Profiles\0001\System\CurrentControlSet\Enum\PCI\VEN_8086&DEV_2485&SUBSYS_00201025&REV_02\3&61AAA01&0&FD\DirectSound\Device Presence]
"VxD"=dword:00000000
"WDM"=dword:00000000

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Video\{34469DE2-6C55-49A6-A579-0D3C2F9EAB34}\0000]
"Acceleration.Level"=dword:00000005

Enable hardware acceleration (100%):

Code:

[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Hardware Profiles\0001\System\CurrentControlSet\Enum\PCI\VEN_8086&DEV_2485&SUBSYS_00201025&REV_02\3&61AAA01&0&FD\DirectSound\Mixer Defaults]
"Acceleration"=dword:00000000

[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Hardware Profiles\0001\System\CurrentControlSet\Enum\PCI\VEN_8086&DEV_2485&SUBSYS_00201025&REV_02\3&61AAA01&0&FD\DirectSound\Device Presence]
"VxD"=dword:00000001
"WDM"=dword:00000001

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Video\{34469DE2-6C55-49A6-A579-0D3C2F9EAB34}\0000]
"Acceleration.Level"=-
