Option 2 – WDDM compatibility maintained, for DX10 cards with no hope of WDDM
1.1 upgrade that fixes the GDI problems, for those that want to maintain Aero
but have almost as close to XP speed as possible:
1. At this point you
should already have a WDDM 1.0 driver installed, with whatever modifications you
have done.
2. If you have the troubleshooting notch available in the Screen Resolution>Advanced Properties, bring it one notch over to the left from Full Acceleration (you may try two over... anymore and D3D is lost).
3. If this
setting is not available (like mine). Open Regedit and navigate to
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Video\{y our video card’s
CLSID – varies from each driver install}\0000 and input
in:
“Acceleration.Level"=dword:00000004
Or
(Try 4, 3 ,2, then 1...
check to make sure Direct3D vis dxdiag is still enabled.. technically at level 3
it is supposed to not work.. but in my case D3D stays running but all 2D
succesfully takes the older recognized pipeline)
4. Merge the following into
the
registry
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Avalon.Graphics]
[HKEY_CURRENT_USER\SOFTWARE\Microsoft\Avalon.Graphics]
[HKEY_USERS\.DEFAULT\SOFTWARE\Microsoft\Avalon.Graphics]
(And
ideally all other user
accounts)
"EnableDebugControl"=dword:00000001
"UseDX9LText"=dword:00000000
"BreakOnUnexpectedErrors"=dword:00000000
"RPCAvalon"=dword:00000001
"RecordAvalonFile"=dword:00000000
"UseReferenceRasterizer"=dword:00000000
"SkipDriverDateCheck"=dword:00000001
"SkipDriverCheck"=dword:00000001
"DisableHWAcceleration"=dword:00000001
"MaxMultisampleType"=dword:00000000
"RequiredVideoDriverDate"="1980/01/01"
5.
DisableHWAcceleration is left enabled, in both cases this is the major reason
for the speed increase -- and even Aero runs better at LOWER cpu usage with it
on.. odd-- whatever it works.
6. This mode will allow the use of Aero, if
done right like this does for me, Aero will run as fast as the XPDM drivers for
both 2D and 3D... much better than stock configuration I had and not what I
expected. Going to windows Classic mode still running WDDM drivers... I gain 20%
increase in speed over the XPDM in 3D gaming, 2D elements (movies, flash) are
faster, the only bog down - that I know off and my CPU can keep pace.. is a
window drag and resize... even YouTube HD is playable... except fullscreen (I am
not expecting to get this working on my X1200 as it is not accelerated... I need
to find a way of fooling it to do so).
