Have you been working hand in hand with Amd/Ati too?
Keep up the good work!
We always work with AMD, NV and Apple. I just know in this case NV had a specific driver issue that slowed down BioShock 2 a little on the current OS. Working with NV during development this was fixed for a newer driver update so I mentioned it.
However you should assume that we work with all three companies on every game to try and make it the most optimised and stable as humanly possible.
Usually most of the performance boosts are done during development so customers never see the before and after as we only ship when we are done, in some rare cases the boost comes in a patch. Sometimes the patch is a game patch sometimes it is a driver patch. For BioShock 2 and NV cards it will come by way of a driver patch.
Cheers,
