What? You think Ray Tracing runs worse on AMD simply because games "are not programmed for AMD?"
watch the video, in framerate mode the series x drop to 900p and series s to 570p, it's a fact
Depends on what your conclusions are, what you're trying to say, are you saying that this performance would be normal for AMD no matter what?
He has a point, AMD have had RT for a week, Nvidia have had it for two years and these games are developed for Nvidia cards.
No one reasonable would draw any conclusions just now.
This is very possible. Why does Nvidia call ray-tracing RTX and not DXR? RTX is a proprietary feature with partial support even on GTX 1080 Ti which was still DX12.1, and not DX12.2 with DXR.

Exactly.
The DXR is not working on the 3080 yet according to the devs. So the performance gains as mentioned by someone else is due to the VRS being enabled (with DXR not actually working even when enabled) .
Nvidia use their own black box libraries for Ray Tracing, it wouldn't surprise me if some of these games don't actually work well if at all in DXR. Proper DXR that is.
The Consoles, at least the Microsoft ones are a blessing as they use that agnostic DXR API, as for the PS5, well games for that are still developed for RDNA2.
A throwback to Game(Don't)Works.
I think it would have been better if AMD have just blocked RTX in some of these titles, like CoD, Minecraft and Control, running them is not good enough when there is something quite obviously seriously wrong with them, its too much of a goal to leave open for Nvidia to point at crying "look see, this how bad AMD's ray tracing is"
Rather than it running 18 FPS just block it from running it at all and say "its not compatible"

If this video is true, the ray-traced shadows works fine (the shadow quality is much better with RT in the video) with 3090 according to the video maker.
That alone would create it's own problems though. Next we'll have peeps saying the RTX Ray Tracing is not even supported on AMD hardware.

No Need to wait they are implying that now.That alone would create it's own problems though. Next we'll have peeps saying the RTX Ray Tracing is not even supported on AMD hardware.
Nvidia sneaks code into the game that only works with Nvidia. Then, its speculated to be the situation. Defender defend Nvidia. Reports come out that its true. Nvidia backpeddles saying that because they put in the resources for it is proprietary for Nvidia. Its implied that Radeon now has to create hw that works with Nvidia software.

I feel dxr has evolved through close cooperation between nv and msoft. NV has been generous enough to open source some critical RT frameworks. So now it's AMDs job to match specs.

This, but reasonable doesn’t really fit with some people’s posting style does it

AMD said that it will not support ray-tracing but select lighting effects.
Even in the raytracing description, it's said that gaming should not use raytracing.
"In 3D computer graphics, ray tracing is a rendering technique for generating an image by tracing the path of light as pixels in an image plane and simulating the effects of its encounters with virtual objects. The technique is capable of producing a high degree of visual realism, more so than typical scanline rendering methods, but at a greater computational cost. This makes ray tracing best suited for applications where taking a relatively long time to render can be tolerated, such as in still computer-generated images, and film and television visual effects (VFX), but more poorly suited to real-time applications such as video games, where speed is critical in rendering each frame."
Ray tracing (graphics) - Wikipedia
This has been happening for a long long time.
Imagine a scenario where you have a game build, you build optimizations for your driver stack into the build you have access to. Things are looking good.
Then, a week or two before you launch you receive a new build, with some additional black box code that's been added.
Suddenly the performance has completely changed.
Yeah, that used to happen a lot. Less so now, thankfully. All AMD hardware in the Consoles, and the eventual bad rep of GameWorks helps. You don't see much GameWorks now.
I know AMD say the devs wanted an open source DLSS competitor but what hasn't been discussed is why the devs didn't ask Nvidia to do the same with DLSS and other proprietary tech.
AMD really should not have let devs dictate what they can or can't do when we all know those same devs have always been perfectly happy to take Nvidia's money to add their stuff at the expense of AMD performance.

Nvidia has shared it's dlss model with Microsoft which will be unveiled as a dx12 feature but AMD now has to match specs.. I guess it's called super resolution. In future devs will have end to end responsibility to implement dlss.
