Microsoft ha rilasciato un fix per Windows Vista in grado di risolvere i problemi durante l’utilizzo di schede in SLI o Crossfire. Ecco la descrizione del problema:

"In some
scenarios, games and benchmarks perform more poorly than expected on a
Windows Vista-based computer. This issue occurs when the games and the
benchmarks use multiple display adapters in a Linked Display Adapter
(LDA) configuration.

A graphics processing unit (GPU) or part of a GPU link may incur a
small scheduling latency on a new Direct Memory Access (DMA) packet.
This is true if the DMA packet is submitted to the GPU that has
previously run out of work and if another GPU in the linked
configuration is very busy. In some scenarios, significant starvation
of one or more GPUs in the linked configuration reduces the expected
performance of an application."
