Cyberpunk 2077 is widely advertised on the NVIDIA website for how it will take advantage of the RTX features.

AMD during the E3 event has widely publicized how its new GPUs are capable of the same performance of the RTX

Now

CDPROJECT, will your new graphics engine have the same visual performance on both AMD and NVIDIA?

We are not talking about frame rates.

We are talking about the effect of shadows and light in the final rendering of each individual frame.
Will there be important differences or not?

I hope not. So that every player can have full freedom to decide on which hardware to play your game.

At the end

Cyberpunk is an exclusive NVDIA RTX.

Very sad to know!

To enjoy the game to its full potential we are forced to buy a new video card from NVDIA: super-expensive RTX.

No freedom for us users to buy other products.

Very sad.

You probably won't need to use RTX at all to enjoy the game, Metro Exodus was another game that was pushing about having RTX support but it ended up looking perfectly fine (and in certain areas better) with it off.
Even if it looks better it probably won't be worth the performance cost it'll have as a lot of games can hack 20 or so fps off of the framerate with RTX on. It's just like the whole hairworks thing with The Witcher 3. outside of the monsters and animals i really thought that hairworks was a huge waste of resources, and Geralts hair and physics just looked off, and in Metro Exodus (which also had hairworks) sometimes the lighting with hairworks would make it look odd colors.

RTX itself is pretty cool on it's own
but unless a game is built from the very scratch with it, i doubt it's worth the cost it has. it has too many little glitches due to the fact that most devs are slapping it into the game after they have already developed the levels to look good with their own lighting, and i highly doubt Cyberpunk 2077 was built from scratch with RTX in mind (probably just like Metro Exodus) Now ofc we haven't played the game so we can't say for sure, but in most cases so far it hasn't been enough to warrant the purchase of one of those cards alone
