NVIDIA DLSS technology works. And it does it really well. In the analysis that we published at the beginning of January, and also in our articles dedicated to the graphics cards of GeForce RTX 30 Family, we check that iteration 2.0 This innovation significantly increases the frame rate per second, especially at 1440p and 2160p.
Also, its impact on image quality in most games is positive. In fact, in some of them it manages to recover a level of detail that He is not present when rendering without DLSS. That it performs so well is surprising, especially when we bear in mind that the first version of this technology had a wide room for improvement.
Image reconstruction using AI is the way to go
Image reconstruction using deep learning sampling techniques is the way to go if we want to achieve sustained cadences above 60 FPS at 1440p and 2160p with ray tracing on. Without this technology even a graphics card as powerful as the NVIDIA GeForce RTX 3080 it suffers to 2160p under these conditions.
Until now only a few development studios had access to DLSS technology, but the landscape has just changed. At the end of last week NVIDIA announced that from now on all developers that use the Unreal Engine 4 graphics engine will be able to use their artificial intelligence image reconstruction technology, which is now available in the form of plug-in for revision 4.26 of this engine.
Developers using @UnrealEngine 4 can now access #DLSS as a plugin for UE4 4.26. With DLSS, developers can enjoy great scaling across all GeForce RTX GPUs and resolutions, including the new ultra-performance mode for 8K gaming. Download today through the UE Marketplace. #GameDev— NVIDIAGameDev (@NVIDIAGameDev) February 11, 2021
This is definitely good news for users. And it is because, as our tests show and as owners of a GeForce RTX 20 or 30 graphics card have found, DLSS 2.0 performs very well in most titles. Additionally, this NVIDIA decision ensures that the number of games that will implement this feature will increase notably in the medium term because the Unreal Engine 4 engine is one of the most used by development studios today.
AMD’s answer: FidelityFX Super Resolution
AMD is working on its own alternative to NVIDIA’s DLSS technology. During the presentation of the graphics card family Radeon RX 6000 this company gave some details about its technology FidelityFX Super Resolution, and it will definitely be your deep learning image reconstruction solution.
RDNA 2, the architecture of the latest AMD graphics cards, is very different from Ampere, which is the architecture of the NVIDIA GeForce RTX 30. The Radeon RX 6000 does not have cores dedicated to running deep learning algorithms similar to the Tensor cores in the GeForce RTX, so it will probably be the programmers who will decide. how many processors stream They need to dedicate to the reconstruction of the image using artificial intelligence.
In any case, although DLSS and FidelityFX Super Resolution technologies will not be implemented in the same way, will pursue the same goal: allow us to play with high rates of images per second at very high resolutions and with ray tracing activated.
It appears, although it is not officially confirmed, that one of the pillars of this innovation from AMD will be DirectML, the library built into the DirectX 12 API that will allow programmers to use the resources of the GPU to implement their image reconstruction algorithms. through deep learning. What we don’t know yet is whether FidelityFX Super Resolution solo will work on RDNA 2, or if it will also do it on graphics cards with RDNA architecture. If I had to bet I would choose that it will only reach the Radeon RX 6000.
We also don’t know for sure when AMD will launch its technology, although a recent leak ensures that it will arrive during next march. In any case, hopefully it will be available as soon as possible. It is clear that users are interested in both NVIDIA and AMD proposing competitive solutions, and DLSS is an asset that for the moment gives NVIDIA a certain advantage. Let’s trust that AMD reply asap.
The news NVIDIA has opened DLSS technology to all developers using Unreal Engine 4: why it matters and what AMD prepares was originally published in Engadget for Juan Carlos Lopez .
