reading a review of the RC1 I stumbled across this:

Moving on from WDDM 1.1, Microsoft has also introduced some changes to GDI that do not require new display drivers. Along with requiring a local copy of window textures, the GDI stack was locked so that only a single GDI application could access it at a time. The GDI stack has been rebuilt so that the lock is more or less removed. Multiple GDI applications can now issue commands to it at the same time, and this is all pushed off to the video card to be its problem.

Is this what will solve the lag problems under GP-GPU? That several apps can issue commands to the vid card at the same time, so that the GPU is no longer locked while executing the tasks and screen refreshes can still happen? Of course the driver / GPU-scheduler still had to be smart enough.. but with nVidias strong push towards GP-GPU I don't think this would be a show stopper.
