Well some did by saying that NV doesn't do it while AMD does when the fact is that AMD and NV are doing the exact same thing.
There is no 'fact' about that at all. This is not about sponsorships as a whole - this is about sponsorships being worded to restrict a competitors technology inclusion if the developer wants to add it on their own accord. This was clear on Day 1 of this controversy.
It's not about NV being more permissive or better about it than AMD or AMD being worse about it than NV, it's almost entirely about whether or not a developer would feel the need to implement multiple solutions in order to have the option available to as many customers of the game as possible.
Ok, then...
Taking an incentive to only offer FSR is easier for the developer than taking an incentive to only offer DLSS. Not to mention developers that might be adamantly opposed to offering any tech that is proprietary and limited to only hardware from one IHV.
That is literally the contention here. You're saying it's
not about "AMD being more permissive", then say it's easier to 'take an incentive' - if one company is offering an
financial incentive to not include something, that is absolutely an issue of permissiveness! Like nobody is arguing that AMD is 'preventing' DLSS inclusion being literally physically restraining developers from adding the requisite dll's, they're 'preventing' by tying support/funding by AMD as a whole for the project if the developer adds DLSS support for some games.
There is no evidence so far that Nvidia is offering any incentive to restrict a developer from using FSR, the only 'evidence' we have on that is a
theory that because Nvidia will promote DLSS-supported games as part of their general marketing, that could provoke a conflict of interest if a game is sponsored by AMD and the developer may be hesitant to include DLSS if Nvidia will then use it as a marketing tool. Nvidia says they provide exclusions from that advertising if requested, but of course we have no idea how often this occurs. What we can simply contrast is the response Nvidia gave compared to AMD's, and even AMD's current response isn't nearly this clear-cut:
NVIDIA does not and will not block, restrict, discourage, or hinder developers from implementing competitor technologies in any way. We provide the support and tools for all game developers to easily integrate DLSS if they choose and even created NVIDIA Streamline to make it easier for game developers to add competitive technologies to their games.
That is quite clear, in at least the way it's phrased, in that they're not actually incentivising the exclusion of FSR - tying your funding to the developer choosing to add FSR would absolutely be a form of 'discourage'. Those types of questions were specifically worded by sites like Gamers Nexus to make that as clear as possible, which AMD refused to comment on.
