That spells out why AMD have such poor RT performance of the 6800xt. Guess AMD will have to go out of business. Buy nvidia.

You really don't want amd going out of business. In fact we need more competitors. I would get rajahs card as a show exhibit when it launches and would encourage everyone who can to do so.

By blocking nvidia cards from enabling it ingame. Stop personally attacking me, i'm not out of my mind because you have no knownledge or understanding.

Directx 12u is supported on the 3080, this includes DXR. The game has to enable the use of this feature on nvidia cards. Godfall blocks use of DXR on nvidia cards. DXR is a standard which means all cards support the same commands and run DXR a standard way. Otherwise DSR games would not run on different hardware. Completely undermining the whole point of having a DXR standard in the first place. Godfall uses Directx DXR as reported here https://hothardware.com/news/amd-godfall-radeon-rx-6000-ray-tracing

The standard sets out how a game should impliment DXR and all cards that want to run DXR games must conform to that standard to be able to state they support DXR. Both AMD and NVidia cards support DXR thus the game will run on nvidia cards. Give they use Unreal Engine 4 and this uses DX12u, there should be no problems what so ever running DXR on nvidia. So why is DXR disabled on nvidia cards? No one knows. Even Control a DXR game that was developed with nvidia help, run fine on AMD cards.

Isn't cyberpunk Nvidia only for ray tracing looking at the new recommend specifications ?

I mean both AMD and Nvidia play the "exclusive features in game X" cards :/

Your right no development will happen on RDNA2 cards and it's RT capabilities, the consoles are dead and games from now on will only be targeted at Nvidia.....

Your forgetting AMD sells the most gaming GPUs and had the most developers working on its hardware.... Consoles
 
4K8K comes to mind :D

To be honest, I don't do it.
I notice the differences during the actual gameplay when they are much more pronounced and exposed.

Using the above only to try to explain what really happens.

But, the best is to compare during live gameplay sessions.

Of course it can but it won`t at the start. That`s the whole point. It needs custom settings just like they do for their Nvidia partners.
https://www.thefpsreview.com/2020/1...deon-rx-6000-series-gpus-at-launch-after-all/

"“We are working together with AMD to integrate ray tracing options for their graphics cards as quickly as possible,” CD PROJEKT RED wrote. “However, this will not be the case when the game launches.”
And yes it is the same with Control. They all need custom settings for AMD because so far they only made custom settings for Nvidia. That`s part of the problem for why AMD ray tracing is so terrible ATM stop talking about tensor cores and all that PR nonsense. :)

AMD's issue is that they dont support a feature like DLSS. This means AMD cards will have poor performance, as Cyberpunk 2077 uses all the features from control. The 6800xt was released basically at the end of cyberpunks development cycle. They are working on the console ports at the moment. 6800xt most likely will run cyberpunk in RT mode. Control has no support for the 6800xt and yet the 6800xt can run Control with poor performance. The poor performance is why 6800xt RT support will likely be delayed, they need to impliment amd fidelityfx super resolution which is yet to be released.

Dubbed FidelityFX Super Resolution (catchy), AMD have told me it will bring “an open, easily adoptable super resolution capability which will boost ray tracing performance at higher resolutions” when it’s finally released, but beyond that… who knows. https://www.rockpapershotgun.com/2020/11/18/amd-radeon-rx-6800-xt-review/

Godfall has no such excuses, DXR support on nviida cards have been around for most of godfalls development cycle. Godfall uses a limited version of RT, one that will run well on nvidia cards (given they are faster).
 
I dont see how many can lose here. If you did not buy Turing, or for me personally came from Vega (not sure I would jump in if I was on a 5700XT) then either the 3080/6800/6800XT are going to be awesome cards to game on. Decent upgrade path and as long as you get at or near to the FE/reference prices its beating the stampede thats your main barrier.

Me personally I am not into RT. I will game as I normally do and am happy with 4k60fps. Development work and other uses will distract me slightly. Some of this also depends on your existing hardware arrangements, so far I have not had to buy anything else to upgrade (touches wood).

You have never played Control? If you dont have a DLSS feature, then performance is really bad if you increase the resolution. Becoming unplayable very quickly above 1080p with the full RT features. The full RT feature set works on AMD cards just fine because both nvidia and AMD support the DXR standard. THe DXR standard is basically nvidia's RTX. Its just AMD have poor performance because of the very reason DLSS was design to fix. AMD have not yet released its version of a feature like DLSS.

Well if they aregoing for performance with just limited lighting using RT. Then their performance will be crap in games like control and cyberpunk. It explains why there is no AMD dlss and why performance is so behind nvidia in dxr benchmarks. Now they are rushing to catch up with DLSS, which they cant because they have no tensor cores. AMD's DLSS feature at best will be like DLSS 1.9. Looks not so great and runs via shaders which they have half as many. I think they will just upscale and sharpen. Even spider-man on the PS5 is like control, they had to tweak the crap out of it to get it to run at 30fps. Tweak the crap out of it, means reduce graphic quality to meet the frame time budget. On an nvidia card and a 6800xt it will look better. On a nvidia card you have dlss to improve frame times, thus you can increase quality within the same budget.

I don't know how good it's going to be but AMD won't be relying on shaders for DLSS..AMDs arch is different from nvidias superscalar CUDA implementation and relies on SIMD units. Those can do more than 2, maybe 7-10 ops per cycle compared to CUDA.

DLSS is a very good adventage for the Nvidia but it has its down sides :

1) doesn't work in every game
2) some games that have it have iq issues like bluring
3) performance gain isn't the same in every game

For DLSS or equivilant Nvidia apparently only had hardware for it, AMD would have to do it in top of what they're already doing in their GPUs
 
Got my PS5 on Thursday, what a fabulous bit of kit for 450, first time I have bought a console and really felt it's more powerful than current gaming rig. 3700X and Vega 56. Will be looking forward to getting a 6800xt AIB in it the next 6 months given what I have seen of RDNA2 so far.

Dude what`s wrong with you? If it`s the same DXR then how can Cyberpunk not offer support for AMD? Or how can Godfall not offer support for Nvidia? Ok Cyberpunk will work bad on AMD, like it works on Control atm. But it should work if it is only the same API.
You are just keep repeating the same nonsense over and over. It is clear that both Nvidia and AMD are using different optimized plugins to make the most out of RT. Otherwise no one will stop one brand or another from running in their game.

Just a heads up. You are arguing with an admitted dup. account.
