I haven't said that they are trying to hide the source code from NVIDIA.
I understand your take, but due to the fact that AMD hasn't give any explanation about why they are delaying the source code release, it is a no brainer for me. This is advertised as open source and multiplatform but nobody can implement it right now unless you sign a deal with AMD.
Not sure why they need to give an explanation?
And also, I still have no idea what difference this month will make in practice.
If you're making a game, getting access to it is as simple as contacting AMD. You don't need a full marketing deal to use FSR, just like you don't need a deal to use any other part of the FidelityFX library.
Even assuming for whatever reason you cannot do that, you only need to wait a month for it.
In the scope of the development of a game, a month is absolutely irrelevant?
If the delay was 6 months or a year, I'd agree something else might be at play.
But a month speaks to me as simply "we didn't get thing ready in time for day one".
Wouldn't be the visual trade-off be more perceptible with VR?
Sure but dropping frames and stutters are much worse than a softer image, and can actually cause sickness is especially sensitive people,
so if you're struggling to hit the required 90/120hz, it's probably a good compromise.
