It has been a subject of a lot and lots of debates, the RTX options from NVIDIA. Is hybrid ray tracing with the additional cash, and why hasn’t the only expertise behind RTX, the DXR API been introduced in the direction of different playing cards. Well, at the moment that modifications with a driver launch from NVIDIA.
You need to run Battlefield 5 or Metro Exodus with ray tracing enabled? You want a GeForce RTX card. The launch of at the moment’s driver opens up DXR help in the direction of NVIDIA Pascal GPUs for the GeForce 1000 and 1660 (6GB and better) collection.
Above the GTX 1080 – the perf hit may be very intensive.
There’s a little bit of a conundrum although, DXR technically solely requires a DX12- or Vulkan-compatible graphics card with acceptable drivers, however the calculations for ray tracing will fall again to the GPU’s compute capabilities and can invoke a giant large efficiency hit. The new driver launched at the moment makes it potential to make use of real-time raytracing in video games through DXR as a part of DirectX 12 with out unique RT cores and thus using the standard compute cores. However, with DXR results enabled, efficiency might be considerably decrease than Turing’s counterparts with specialised RT cores.
The GTX 1660 Ti truly holds floor fairly properly if you evaluate it with that GTX 1080
NVIDIA has been engaged on DXR through compute shaders operating over its CUDA (shader) cores. For current GeForce GTX 1660 collection playing cards adopters meaning there might be a efficiency profit as Turing consists of separate INT32 cores which aren’t merged with FP32 cores as Pascal has), that signifies that the 1660 playing cards will run considerably higher than the Series 1000 (Pascal). It nonetheless will take a large perf hit because it clearly remains to be missing RTX cores.
The dark-colored charts under derive from NVIDIA themselves. The benchmark outcomes as introduced by NVIDIA are pretty spot on to what we’re seeing.
DLSS stays solely for Turing RTX
From now on Raytracing will now not be out there solely on GeForce RTX at Nvidia. But with DLSS (Deep Learning Super Sampling) it’s totally different. The different AI-based antialiasing will proceed to be supplied solely with the devoted tensor cores of the RTX household, Nvidia stated in a Q & A.
So briefly, folks can allow DirectX Raytracing (DXR) on GeForce GTX 1060 6GB and better graphics playing cards through a Game Ready Driver replace, anticipated in April. DLSS, no bueno.
Below you’ll be able to see quite a lot of slides with perf numbers that NVIDIA made, we’ve had no early driver to check this. In the course of at the moment, we’ll run some numbers internally on our aspect and can add these in the direction of this text. So, to be up to date. The dangerous information is that Raytracing efficiency will suck on non RTX supported playing cards, the excellent news is you can now visually test whether or not or not you want RTX Raytracing in your video games, and might resolve whether or not or not that is one thing in your improve path. For some excellent news, NVIDIA might be making three demos out there at the moment as properly, the Star Wars reflections demo, the Justice tech demo and the Atomic Heart Tech demo which must be a very nice demo to mess around with and immerse your self in a raytraced atmosphere.
Meanwhile, you’ll be able to obtain and take a look at the brand new driver right here.
