ANSWER:
One of the advantages of Windows 7 is that, using its standard IEEE-1934 driver stack, users can operate Point Grey IEEE-1394b cameras at full S800 speed in conjunction with other devices on the same host adapter card. As described in Knowledge Base Article 171, the Windows XP Service Pack 2 and Service Pack 3 low-level drivers currently limit 1394b devices to S100 speed, while the Windows Vista drivers limit devices to S400 speed. This limitation has been removed from Windows 7.

| Power management. Similar to Vista, power management features may enable CPU sleep states or throttling. A typically observed effect of these features is image tearing. |
We recommend that users configure their system to use the least aggressive power management schemes as a first step to debugging observed issues. |
All products |
| Aero themes. Early testing indicates these themes are resource intensive. |
We recommend disabling Aero themes as a first step when debugging any observed issues. |
