Nvidia announces DLSS 2.0 to appease fans over next gen GPU delays

Nvidia put a ton of effort into making a new version of DLSS that ran on the traditional shader cores of a GPU, making a DLSS model that was more adaptable and could be used on non-RTX cards. While the feature wasn't used as well in its first iteration, NVIDIA is now confident that they have successfully fixed all the issues it had before. But Jesse's not the only one to benefit, because Mechwarrior 5 of all games is getting the new DLSS too. DLSS taps the dedicated tensor cores inside the cutting-edge GPUs, using their machine learning chops to boost frames rates and increase the resolution you're able to play at-a key complement to ray tracing, as the lighting technology severely taxes performance when it's active. If running a game at 4K, selecting the Quality setting would run at that resolution. Tackling the first of these, Nvidia asserts that "DLSS 2.0 offers image quality comparable to native resolution while rendering only one quarter to one half of the pixels". Nvidia also promises improved image quality thanks to new temporal feedback techniques, offering sharper and more detailed frames. This improves frame rates and eliminates previous limitations on which GPUs, settings, and resolutions could be enabled. Needless to say, DLSS is now a hit or miss feature and game developers remain quite reluctant towards implementing this feature since it has daunting requirements involving the creation of separate neural network models for each game at all supported resolutions. This last point is important, as it should mean that a lot more developers use it. DLSS 2.0 does still need access to the buffers though, and so does need per game integration as opposed to just magically working with everything, but it's still definitely a step in the right direction. For DLSS 2.0, Nvidia is introducing a single generic neural network that can adapt to any game.
Customizable Options - DLSS 2.0 offers users 3 image quality modes - Quality, Balanced, Performance - that control the game's internal rendering resolution, with Performance mode enabling up to 4X super resolution (i.e. 1080p → 4K). This means more user choice, and even bigger performance boosts.

Doug Collins (R-Ga.), Matt Gaetz (R-Fla.), and Mark Meadows (R-N.C.) also went into quarantine after attending the conference. Local newspaper Estado de S.Paulo reported that Bolsonaro has been tested for coronavirus, with results expected on Friday.
Let's take a quick look at how DLSS 2.0 works and some of the results that NVIDIA is showing off so far.
For those game supported, DLSS 2.0 offers three image quality modes.
Behind the scenes, DLSS 1.0 could only be trained on a per-game basis-meaning Nvidia needed to devote its supercomputer's prowess to each game that integrated the technology. The feature seeks balance, increasing graphics performance and FPS during matches, while also improving the sharpness of images. Instead, there's a generalized algorithm that will allow any developer to implement the tech into their games.
