Device0 refers to the first video card installed on your system. When set to 1, this value requests the driver to wait for a vertical sync before programming the ramdac with a new pointer shape or a new palette. If you notice stray pixels flashing around the pointer, setting this value to 1 might fix the problem. Setting it to 0 gives you slightly better performance.
II-30 | Hive: | HKEY_LOCAL_MACHINE |
Key: | System\CurrentControlSet\Services\mga64\Device0 | |
Value Name: | User.SynchronizeEngine | |
Data Type: | REG_BINARY | |
Value: | 0 |
Device0 refers to the first video card installed on your system. When set to 1, this value requires the driver to wait until the Millennium hardware is ready to accept new data before programming the next operation. Setting it to 0 results in better performance. On most x86-based systems, the PCI logic should ensure that such a check is redundant. If youre experiencing problems that might be related to timing (with communication programs, for instance), setting this value to 1 may help.
II-31 | Hive: | HKEY_LOCAL_MACHINE |
Key: | System\CurrentControlSet\Services\mga64\Device0 | |
Value Name: | User3D.DoubleBuffer | |
Data Type: | REG_BINARY | |
Value: | 1 |
Device0 refers to the first video card installed on your system. When set to 1, this value requires the Matrox Millennium or Mystique memory to allocate a back buffer. Set this value to 0 if you dont require a back buffer. Set this value to 1 to fully accelerate 3D animation.
II-32 | Hive: | HKEY_LOCAL_MACHINE |
Key: | System\CurrentControlSet\Services\mga64\Device0 | |
Value Name: | User3D.Zbuffer | |
Data Type: | REG_BINARY | |
Value: | 1 |
Device0 refers to the first video card installed on your system. When set to 1, this value requires the Matrox Millennium or Mystique memory to allocate a Z buffer. Set it to 0 if you dont require a Z buffer. To accelerate your 3D rendering, set this value to 1. Setting this value and the User3D.DoubleBuffer to 0 effectively disables any 3D hardware acceleration.
These registry entries let you tweak the features and performance of the PowerDesk software that ships with the Matrox Millenium and Mystique cards.
II-33 | Hive: | HKEY_LOCAL_MACHINE |
Key: | System\CurrentControlSet\Services\MGACtrl\PowerDesk | |
Value Name: | PowerDeskPath | |
Data Type: | REG_SZ | |
Value: | C:\Program Files\MGA NT PowerDesk |
This value sets the path to the configuration files for the Matrox PowerDesk configuration software. For example, to find out where the monitor configuration files are, look here for the path, then look in the MON subdirectory located under this path.
II-34 | Hive: | HKEY_LOCAL_MACHINE |
Key: | System\CurrentControlSet\Services\MGACtrl\PowerDesk\ CurrentSettings | |
Value Name: | BitsperPixel | |
Data Type: | REG_DWORD | |
Value: | 08h |
