Microsoft began rolling out Windows 10 October 2018 Update (version 1809) through its regular update channels. The update introduces several improvements to the operating system's user interface, expand on its Timeline features that let you pick up your work where you left off, and comes with a boatload of under the hood performance improvements relevant to PC enthusiasts and gamers. These include the latest update to DirectX that adds DirectX Ray-tracing API features (DXR), the latest version of WDDM, and native HDR standards management settings via Display Settings. To get it, simply make Windows check for updates.The change-log follows.

NVIDIA's Turing-based RTX 20-series graphics cards have been announced to begin shipping on the 20th of September. Their most compelling argument for users to buy them is the leap in ray-tracing performance, enabled by the integration of hardware-based acceleration via RT cores that have been added to NVIDIA's core design. NVIDIA has been pretty bullish as to how this development reinvents graphics as we know it, and are quick to point out the benefits of this approach against other, shader-based approximations of real, physics-based lighting. In a Q&A at the Citi 2018 Global Technology Conference, NVIDIA's Colette Kress expounded on their new architecture's strengths - but also touched upon a possible segmentation of graphics cards by raytracing capabilities.

During that Q&A, NVIDIA's Colette Kress put Turing's performance at a cool 2x improvement over their 10-series graphics cards, discounting any raytracing performance uplift - and when raytracing is indeed brought into consideration, she said performance has increased by up to 6x compared to NVIDIA's last generation. There's some interesting wording when it comes to NVIDIA's 20-series lineup, though; as Kress puts it, "We'll start with the ray-tracing cards. We have the 2080 Ti, the 2080 and the 2070 overall coming to market," which, in context, seems to point out towards a lack of raytracing hardware in lower-tier graphics cards (apparently, those based on the potential TU106 silicon and lower-level variants).

EA-DICE, in an interview with Tom's Hardware, put out some juicy under-the-hood details about the PC release of "Battlefield V." The most prominent of these would be that the commercial release of the game will slightly dial back on the ray-tracing eye-candy we saw at NVIDIA's GeForce RTX launch event demo. DICE is rather conservative about its implementation of ray-tracing, and seems to assure players that the lack of it won't make a tangible difference to the game's production design, and will certainly not affect gameplay (eg: you won't be at a competitive disadvantage just because a squeaky clean car in the middle of a warzone won't reflect an enemy sniper's glint accurately).

"What I think that we will do is take a pass on the levels and see if there is something that sticks out," said Christian Holmquist, technical director at DICE. "Because the materials are not tweaked for ray tracing, but sometimes they may show off something that's too strong or something that was not directly intended. But otherwise we won't change the levels-they'll be as they are. And then we might need to change some parameters in the ray tracing engine itself to maybe tone something down a little bit," he added. Throughout the game's levels and maps, DICE identified objects and elements that could hit framerates hard when ray-tracing is enabled, and "dialed-down" ray-tracing for those assets. For example, a wall located in some level (probably a glass mosaic wall), hit performance too hard, and the developers had to tone down its level of detail.

After we've covered news of UL's (previously known as 3D Mark) move to include a raytracing benchmark mode on Time Spy, the company has contacted us and other members of the press to clarify their message and intentions. As it stands, the company will not be updating their Time Spy testing suite with Raytracing technologies. Part of the reason is that this would need an immense rewrite of the benchmark itself, which would be counterproductive - and this leads to the rest of the reason why it's not so: such a significant change would invalidate previous results that didn't have the Raytracing mode activated.

As such, UL has elected to develop a totally new benchmark, built from the ground up to use Microsoft's DirectX Raytracing (DXR). This new benchmark will be added to the 3D Mark app as an update. The new test will produce its own benchmarking scores, very much like Fire Strike and Time Spy did, and will provide users with yet another ladder to climb on their way to the top of the benchmarking scene. Other details are scarce - which makes sense. But the test should still be available on or around the time of NVIDIA's 20-series launch, come September 20th.
