You know the thing that really pisses me off about the whole Gameworks/TressFX thing is how inconsistent nVidia is in their stance.
So here's a quote from Cem Cebenoyan
, Director of Engineering, Developer Technology:
Seeking some clarification, I asked if perhaps AMD’s concern was that they’re not allowed to see the game’s source code. Cebenoyan says that a game’s source code isn’t necessary to perform driver optimization. “Thousands of games get released, but we don’t need to look at that source code,” he says. “Most developers don’t give you the source code. You don’t need source code of the game itself to do optimization for those games. AMD’s been saying for awhile that without access to the source code it’s impossible to optimize. That’s crazy.”
Ok so when it comes to Gameworks and AMD wants the source code to optimize, nVidia is basically saying it's a pile of BS.
Now compare the above with what was said
when TressFX ran poorly:
We are aware of performance and stability issues with GeForce GPUs running Tomb Raider with maximum settings. Unfortunately, NVIDIA didn’t receive final game code until this past weekend which substantially decreased stability, image quality and performance over a build we were previously provided. We are working closely with Crystal Dynamics to address and resolve all game issues as quickly as possible.
Please be advised that these issues cannot be completely resolved by an NVIDIA driver. The developer will need to make code changes on their end to fix the issues on GeForce GPUs as well. As a result, we recommend you do not play Tomb Raider until all of the above issues have been resolved.
In the meantime, we would like to apologize to GeForce users that are not able to have a great experience playing Tomb Raider, as they have come to expect with all of their favorite PC games.
Interesting, so apparently when it's nVidia that needs to optimize for an AMD tech, they somehow suddenly can't do it on their own and need the source code and the dev's help.
