No they didn't. If they actually said that give a timestamp in the video lol.
Just watch from 04:23 until the end
The video does not say what you are claiming. From 11:30 to 12:04 he describes what changes are needed to make it work; never does he say it is impossible and unplayable. The only thing he says that is remotely close to what you are saying is him expressing doubts about quality because CD Project Red won't be porting directly, and this is from 12:04 to 12:30 (and this is still completely different from what you are saying).
Dude, 'timestamp' is not the same as 10 minutes of a video - that's a useless response. If you truly believe that you are right, please give a direct quote from the video of anything DF says that is close to your claims. I don't understand how you insist on something when the source you are claiming directly contradicts you.

And don't worry - I didn't actually watch the whole video to find a useful timestamp - I had already seen it and remembered where he spoke of optimisation. Took like one minute; writing this comment took longer.
