Well, it's "with RTX" and not "with raytracing" so probably not.

Im sure it will be playable, just a matter of if it will be worth it at the settings it will actually run at. Seriously doubt fsr2 will ever be added though with all the nvidia sponsorship.

They are the same thing. There are no game where ray tracing only works on an Nvidia card. Performance is a different story, but Portal RTX will definitely work on AMD cards. 

 

RTX is just Nvidia branding/logo and nothing more. If you see a game that is advertised as RTX, it probably means it has ray tracing and DLSS support, but it does not mean the ray tracing is only going to work on an RTX card. 

I doubt Valve would make this without some scaling options. I've been playing Ghostwire Tokyo recently which has RT and FRS2. Runs and looks surprisingly well for how heavy the RT reflections are in that game. Metro Exodus also works pretty well on AMD cards, even without FSR2. I suspect portal RTX will have some scaling options that will allow for it to run about as well as those other two games do on current AMD cards.

Well, there are some games out there that support "RTX raytracing" but not "Radeon Rays" or whatever AMD called it, so 🤷

That's about my experience with it. I did have to laugh at Nvidia calling a game from 2007 getting RTX as "Next gen".

No, they're are not. Any game with any form of ray tracing will work on AMD cards no matter how many times they say RTX in the promos.

 

If you know of such a game, tell us what it is.

As of right now, I don't know because I don't really keep up with these things. The main one that stands out for me is ACC. That supported nVidia RTX raytracing from launch. It didn't support raytracing on AMD cards until update 1.8 on 3rd December 2021, a little over 3 years after launch and 1 year after the first AMD card to support real time raytracing was released.

I don't know what ACC is. 

 

If you're referring to Assetto Corsa Competizione, that game does not have RT. It was initially advertised as a game that would have RT added, but it never happened. Lots of games advertised RT when Nvidia came out with the RTX branding and then never actually followed through. 

 

The game did get dlss added and has RT mods, but no official RT support. 

 

But even if that were the case, a game being late to add support for cards that came out after the game did is a lot different than saying RT is sometimes exclusive to Nvidia. If there are any games that don't do RT on AMD, it's probably for that reason (that the game came out before AMD 6000 GPUs and the game was never patched) and that reason only. there won't be any games going forward that don't do RT on Nvidia and AMD, and Intel now too. 

 

As for Protal RTX, it says it requires a dx12 dxr card, not an Nvidia card.

 

 

Nvidia wanted people to think RTX means ray tracing and that ray tracing is something exclusive to Nvidia. They made sure to get RT hardware out first so they could brand RT as an Nvidia feature, but RT is really a DX12/Vulkan feature first and foremost, the hardware came after RT was planned/created for DX12. 

 

The term "radeon rays" predates RT hardware and was initially a software solution to make RT renders that would run on CPUs via OpenCL. It supports DX12 and Vulkan today, and it's hardware agnostics. There is no "RTX" vs "radeon rays" in games. There's just DX12/vulkan RT. So again, there is no reason at all to think a game will only do RT on one or the other unless it came out before AMD 6000 and was never patched to enable RT on AMD hardware.

RTX to my understanding is just pre built libraries to take advantage of the ray tracing capabilities of the RTX cards making it easier on developers.

Sure RTX is branding but they have APIs and SDKs for people to use to do ray tracing things easier in their engines.  So there is all the software side of it they bring to the table too.  AMD might have some of this too I'm not familiar with it but there is more to RTX then branding.  

 

EDIT:  I guess my question would be if they used the RTX Path Tracing SDK to build out that ray tracing functionality could an AMD card use it, or would they have to use some other kind of path tracing in for amd to use.  I understand they can both do path tracing but can both always use the same implementation of path tracing.

Nvidia and AMD have always had APIs built into their drivers, games, directx, Vulkan. It's nothing new. Nvidia and AMD surely both have tools to help devs build features, but any RT features they build would still rely on the agnostic APIs they work with like DX12 and Vulkan. Games could be optimized more for one team or the other, but they will always work on both unless the dev does something very unusual. 

 

IIRC AMD was more heavily involved in collaborating with Microsoft in the creation of DX12 and DXR than Nvidia was. 

 

Any notion that RT is an RTX feature and not an API feature of DX12 and later on Vulkan as well is just not correct. RTX is just Nvidia branding, just like GTX was before RTX.

Any RT is going to be DX12 or Vulkan based and will run on any card that supports DX12/Vulkan RT unless the dev does something very unusual. 

 

Example: The new Intel cards support RT and they can run RT on all the games that have it. This is because RT is an API feature, so as long as the hardware supports the API it will work. 

 

Crysis Remastered is the only game I know of that only does hardware based RT rendering on Nvidia cards, but this is a very unusual case. That game uses DX11 and Crytek build a custom way to have DX 11 make calls to certain aspects of DX12 without requiring DX12, and they built this while Nvidia was the only RT hardware around. They never added support for AMD cards but their weird RT setup runs in software and even runs on the PS4pro and Xbox1x so AMD cards can still do it, it just doesn't run on the RT hardware with AMD cards.

No doubt Nvidia is ahead in terms of performance, and with the wide availability of DLSS on RT games, they are even further ahead that the actual hardware performance is, so for sure the performance for AMD 6000 GPUs on games like Portal RTX will be questionable but it will still technically work. 

 

I've seen numbers that the 4090 runs Portal RTX at an average of 24 FPS in 4K native with no DLSS at max settings. If the game doesn't have any lower visual settings options, which seems really unlikely, then probably not many cards that don't support DLSS3 will be able to get playable performance at all. But I'd assume Nvidia would want the game to run on GeForce 2000 series cards to some extent which means it should be possible to get playable performance from AMD cards as well. Sure they can use DLSS2, but worst case scenario and AMD card can do the same performance as GeForce 2000 just without DLSS upscaling. Might be playing Portal RTX and 720p on AMD cards, but it should be doable.
