Earlier crd also had such bugs as wndows revisions stepping between white paper specs that chaged such things as single to dual buffers (earlier higher resolutions "went away" with the demand for more buffer memory for dual buffer implementation in a later DirectX implementation. Similar types of issues may be involved here: you have to watch all of theinterface nteractions cross version changes, registry changes, and hidden flags. A realpain.

If so, top tier support for the particulr card using the ABI for OpenGL may be able to tell you whih ibrary entrypoint is the cruxm, which can then be replaced with a custom routine, if you really need it. Normally with a high end cardm the rutines should automatically kck in. If possible ty a step forward to ultimate Beta, then a step back to earlier cversions of the car ddriver and any ABI in the graphics area (OpenGL, J, etc.) you can get to; se if any combination gets a higher rate out of the card; because you may uncover a valid driver/ABI library bug causing a failure of one specific routine with a fallback to a gener ic running at a much slower rate.
