195.36.31 driver and Quadro 2000/4000 ?
We have found a number of issues using the 256 or 260 series drivers with Quadro 4000 and 2000 cards - which 'go away' when we use the older 195.36.31 driver.
According to the release notes, the Quadro 4000 was not supported until the 256.44 driver and the Quadro 2000 was not supported until the 260.19.12 driver - so we were quite surprised that the 195.36.31 appears to work fine (and better?) with these cards.
At the moment, we are not sure if our problems are with in-house or 3rd party code, so I don't want to point the finger at problems with the 256/260 drivers just yet.
Is it just luck that the 195.36.31 driver works with the Quadro 2000/4000 cards - or are we likely to run in to other issues?
