Cyberpunk 2077 - What you need to run it

You're right that it's not AMD vs Nvidia, but wrong about the rest.
Both AMD and Nvidia do RT through Direct X, the coding is not done differently for each company.

Nvidia's GPU offloads the work onto Tensor cores, AMD's doesn't so Nvidia gets much better performance. It's as simple as that

The coding the developers do is exactly the same

How is it the same? The devs still need to use the hardware acceleration available to them to boost performance. Using nvidia cores vs amd cores I am very sure they is a difference how a game developer will need to take into consideration.

They are two completely different GPUs with the same end goal.

Ohhh, that isn't good and surprised to read that. Maybe a retaliation for Godfall being RT exclusive to AMD?

It appears to be AMD not wanting to be benchmarked against Nvidia with RT in such a large title. Perhaps Godfall has the same reasoning for blocking Nvidia.

I'm not even sure any of this is right, both offload to fixed function hardware, NV to RT cores then tensor cores deal with denoising and dlss etc. AMD offload to their ray accelerator core per shader. Both use fixed function hardware so your comparison im not sure holds water, NV's tech at this point is simply more mature.

They also don't necessarily do it through direct X/DXR, other API's such as vulkan also have ray tracing code paths.

I do genuinely feel it isn't GPU vendors lockinng each other out but more the fact that GPU vendors need to send devs to game developers to get it working correctly (maybe for the interim). Hopefully in the long run, it is a case of both ""just work" and no internal tinkering needed but I imagine that is a way off.

Perhaps. But they wont just shut AMD out altogether. It's on the consoles so must work to some degree on AMD hardware also.

Agreed, I think the release day stuff is all marketed towards NV though due to the tie in or supposed tie in at launch.

I am super excited for this game and will be the reason I get back to proper ghaming, as well as upgrading in the near future. CDPROJECTRED have released the recommended specs for playing and with RT looking sweet as, I guarantee a few of us can't wait to play it.

May I ask how this table makes any sense?
The difference between a 1060 and 1660S is approximately 30% and they are in the same column, while the 2060 is only 15% faster than the 1660S and it represents the next tier?
Also if RT will be used in parallel with DLSS which could boost back the performance lost.... what's the point of making a separate column and especially recommending 2060 with no RT and 3070 with the same setting for the RT.....

Can anyone confirm that RT in this game will mainly do 2 things: reflections and more detailed shadows. Apart from this the game will look exactly the same with RT, yes?

Thays what i thought too, amd pays for er lets say 1 year exclusive rt with godfall. Nvidia does it with cyberpunk. If its true thats sad, they are behaving like children.

While exclusivity is generally pretty bad for gamers, there is a silver lining. Many developers wont touch new technology until it becomes industry standard and a "must have" to keep up among their peers, tech that no one else uses tends to get ignored for a very long time. It takes new skills and new talent as well as investment to integrate this new technology, that makes it expensive and risky. When AMD and Nvidia reach out the developers to do some kind of deal regarding exclusivity they force the new features into the ecosystem and set a new, higher, bar. After games like CyberPunk and CoD Cold War any FPS that wants to be seen as having "good graphics" relative to its peers will need to have some form of ray tracing. I'd take the trade off of some exclusivity early on if that helps move along adoption.

From memory there were four toggles. With some form of global illumination and ambient occlusion being the others. I don't think any other rtx game as yet has tried all of that at once. I suspect the requirements are for 30fps but I'd love to be proven wrong. In control my 2080ti has to upscale from 1080 using DLSS to hit 4k 60 and that's with less effects and less going on. There was some console footage released earlier this week if you want to get a look at how it might look with the settings backed off.

Edited to add- apparently ray trace diffuse illumination rather than global illumination, easier to run but still expecting it to be a bugger to run with everything turned up to 11.

The work the Devs do is the same because it is using DX. How the cards deal with it afterwards is different, but coding in the DX calls is the same regardless of vendor

This is a Cyberpunk thread which uses DX.
Nvidia created their own calls for the Vulkan api because there was nothing else they could do, so that is different and has no relevance here
