I don't worry about the production stuff, I mean, they have experience in that domain, unlike most of us.
Base on those numbers, even if the ramp take longer than expected, backers "orders" should be manufactured and probably shipped by the end of the year (that's what I hoped considering i'm a #5000+ backer).
I'm more interested in those "optimisations" for RTX that they are talking about. Is this really related to multi view rendering ? I though this had to be implemented by the game devs.
Anyway, I really hope some game devs will implement DLSS. It looks very promising, but we also so results from tighly controlled demos, provided by nvidia so far.
Then what would have happened if the parts had to be switched with other ones due to issues or feedbacks?!
You're only sure of what parts you will need once the prototyping phase is complete. Sure some standard parts will always be needed, but I'm pretty sure the bottleneck is not on these, and more on the specific parts for this project.
And so, that wouldn't have been efficient to wait for significant amount of parts before starting production if, as they said, even pimax production lines need to ramp up.
