Which you well know is not open, they do naff all to aid the nouveau driver teams either. well apart from holding back firmware so the team can do the relevant bits to add support for new cards. .
I know the gamesworks code is not Open Sourced licence, but to all intents and purposes it is the same thing unless you are some long haired hippy. From a developers perspective, any developer can download the code, modify and uses it as they wish, but they do have to pay a license fee for use within a commercial product, and can't distribute modified code as their own. AMD's GPUopen is in reality much the same for a developer with the difference being that they don;t pay for a license fee but then don;t get any support form AMD either. With gamesworks the license fees covers support. There is a very good reason why a developer is more likely to pay for a Gamesworks license and get supported code than use GPUOpen.
to be honest trying to say Nvidia is a big support of open source like intel/amd is laughable.
I admit they have released things in the past but come on D.P.
Edit:
You've confused me on this one.
Some typos. Freesync is NOT open source, is is closed source propriety. It also isn;t free, it just doesn't have a license fee. Freesync is AMD"s closed proprietary solution leverage Adaptive Sync. Adaptive sync itself is also not open source, but an industry standard (much like CUDA is for example).
All of this begs the question why people playing closed source computer games that use closed source libraries and closed source graphics APIs, developed with closed source software, compiled with closed source compilers, running on a closed source operating system, with an AMD GPU using closed source windows drivers and closed source firmware, on a platform where all the hardware is closed source really care that there exists open source drivers for an Operating system they don't use?
I use linux and open source software all the time. I don;t touch Microsoft or DX with a barge pole. As a developer, I like to use open source libraries when they are suitable, but will happily use closed source if it does what i want. And in 90% of cases closed source libraries and software are just massively superior. I don't give a dman that a company that invested millions into software doesn't share that with others, just like I don;t care that Sony doesn't share details on how they make TVs, Ford doesn't share details of their car design, and I have no way of knowing all the details of closed source Ryzen CPU for example.
