In a press occasion main as much as AMD’s E3 livestream, the corporate clarified that it was not but prepared to maneuver ahead with accelerated ray tracing in its new graphics playing cards. It did, nonetheless, announce some new methods on the planet of upscaling and post-processing to compete with Nvidia’s DLSS (Deep Studying Tremendous Sampling).
Often called Radeon Picture Sharpening, AMD’s answer is an clever sharpening expertise that gives a raise within the visible high quality of a recreation with out a dip in efficiency. The impact takes a take a look at the excessive distinction components of any given scene in a recreation and artificially attracts out extra element. AMD says this sharpening of textures makes 1080p look near 1440p when upscaled on a better decision monitor.
AMD confirmed a screenshot from a recreation and highlighted how Radeon Picture Sharpening pulled out crisper particulars within the shadowy rocks from the darker points of a picture with out interrupting any anti-aliasing softening taking place close to the sunshine supply.
Not like DLSS, which have to be applied on a game-by-game foundation, Radeon Picture Sharpening is an easy swap. In keeping with AMD, it simply works.
Nvidia by no means pitched DLSS as an answer for upscaling. As a substitute, it was meant as a efficiency enhancement for Nvidia’s RTX ray tracing. Nonetheless, in our testing, DLSS resulted in blurry picture high quality at excessive resolutions to compensate for that efficiency. AMD had each options operating Battlefield V side-by-side — the Nvidia system at 4K with ray tracing and DLSS on, and the AMD system with Radeon Picture Sharpening in 1440p. The outcome was very comparable, with the AMD system wanting near 4K because of the added sharpness of RIS. And, as a result of it was nonetheless technically taking part in at 1440p, Battlefield V hit framerates upward of 90 FPS.
As of now, nonetheless, RIS is barely obtainable on AMD’s new Radeon RX 5700-series graphics playing cards, and doesn’t but embrace help for DX11. AMD says it’s solely a matter of sources, however Radeon Picture Sharpening is presently solely obtainable for DX9, DX12, and Vulkan.
FidelityFX and ray tracing
AMD has taken its DLSS answer even additional. It additionally introduced FidelityFX, a open-source developer toolkit that might have a good wider affect on future video games. Probably the most important instrument within the equipment is CAS (Distinction Adaptive Sharpening), which relies on the same set of expertise as Radeon Picture Sharpening.
Not like Radeon Picture Sharpening, Distinction Adaptive Sharpening have to be applied individually by video games, however it’s all fully open supply and free for builders to make use of by way of AMD’s GPUopen.com. It’ll even work on Nvidia playing cards, in keeping with AMD.
The options in FidelityFX give builders extra management over in-game visuals, tweaking sharpness for final outcomes. It’s even attainable to provide gamers guide management for customized outcomes. Radeon Picture Sharpening, in contrast, is an on/off swap that may’t be custom-made.
Ray tracing is coming. Ultimately.
Whereas AMD helps the software-enabled ray tracing that’s been obtainable for years now, AMD insists recreation builders are cautious about committing to ray tracing. As a substitute, AMD says builders are asking for options like CAS, which permits for mass adoption. AMD claims that in contrast to DLSS and ray tracing, AMD’s options are led by what builders ask for, not what they wish to push on builders.
AMD reaffirmed that ray tracing would finally want to incorporate acceleration, however gave no clear indication when that would seem in future playing cards. AMD additionally talked about that the eventual answer would transfer to “full scene ray tracing leveraging cloud computing,” although it didn’t elaborate extra on how that will occur.
Adoption of each DLSS and ray tracing has been disappointing, as few builders have been prepared to combine Nvidia’s options. The few video games which have used it, have applied in very restricted situations, leaving the impact on the general picture high quality underwhelming.
AMD’s persevering with hesitant public stance ray tracing is attention-grabbing given what we all know in regards to the subsequent technology of recreation consoles. Each Xbox Scarlett and the PlayStation 5 will help ray tracing, and each will use AMD’s RDNA graphics structure. That makes it clear that ray tracing is deliberate — it could not arrive in AMD till late 2020.
