An APK teardown helps predict features that may arrive on a service in the future based on work-in-progress code. However, it is possible that such predicted features may not make it to a public release.

Why it matters: Most people think of multi-frame generation when they hear about Nvidia DLSS 4, but the transformer model upgrade in DLSS Super Resolution might be the update’s most consequential upgrade. Many games can already benefit from the feature, and it’s likely to become the standard across upcoming releases.

The latest version of Nvidia’s DLSS Super Resolution and Ray Reconstruction SDK, released on Wednesday, brings the transformer model out of beta. Promoting the upscaling technology into DLSS’s stable branch will likely broaden its adoption in upcoming PC games.

First introduced in January alongside Nvidia’s RTX 50 series graphics cards, the vision transformer model replaces the long-standing convolutional neural network previously used in DLSS. This marks the most substantial improvement to Nvidia’s image reconstruction method since DLSS 2 popularized the technology in 2020.

Although DLSS has earned praise for using machine learning to scale images to higher resolutions with good image quality over the past several years, the process isn’t without visual flaws. Issues that often occur include ghosting, shimmering, and smearing. Ray Reconstruction, which combines denoising for ray tracing with the DLSS algorithm, can also sometimes worsen the problem.

DLSS 4’s transformer model alters the algorithm to minimize these blemishes, resulting in a noticeably cleaner image, even when upscaling from half resolution in performance mode.

Our testing shows that, while AMD’s competing FSR 4 method beats DLSS 3, DLSS 4’s transformer model takes the lead. While Nvidia’s marketing for DLSS 4 mostly focuses on multi-frame generation, which is exclusive to the RTX 50 series GPUs, the transformer model which improves upscaling quality on games supports RTX 20 series and newer.

While many prominent games such as Doom: The Dark Ages, Dune: Awakening, Stellar Blade, and F1 25 have adopted the beta version of DLSS 4 since January, some notable recent titles still default to DLSS 3, such as The Alters, Oblivion Remastered, Expedition 33, and Assassin’s Creed Shadows.

The next major game to upgrade to DLSS 4 will likely be Diablo IV when the Season 9 update launches on July 1.

Users can also force DLSS 4’s transformer model into many older DLSS-compatible titles in the Nvidia App by navigating to Graphics > selecting the desired game > clicking on DLSS Override Model Presets under Driver Settings > and selecting Latest in the drop-down menu.

You can also try third-party apps like DLSS Swapper, DLSS Updater, or Optiscaler.

Recap: The Raspberry Pi 5 was launched in 2023, delivering more than twice the performance of the previous generation. The board was also instrumental in bringing a small, yet significant change in how the UK foundation is actually printing its single-board computers. By changing the way Raspberry Pi boards are assembled and components are soldered, the maker improved its operations in what it described as “massive” ways.

Raspberry Pi Hardware Engineer Roger Thornton explained the change in a recent blog post. Working with its manufacturing partner Sony, the UK organization gradually implemented a soldering technique known as intrusive reflow soldering.

The new method improved production quality, reduced e-waste, and lowered the company’s environmental impact, Thornton stated.

Intrusive reflow was first used to produce Raspberry Pi 5 boards and is now being applied to earlier models as well. This new manufacturing process resolved the inefficiency issues caused by previous soldering methods, which relied on distinct through-hole connectors and surface mount technology (SMT) machines.

Through-hole connectors require strong solder joints made through the printed circuit board and cannot be handled by the SMT machines that place individual parts.

In the early days of Raspberry Pi production, parts were inserted by hand before being handled by robots. A subsequent soldering step, where boards passed through a molten solder bath, was used to secure everything in place.

The improvements led to a 50 percent reduction in product returns, a 15 percent increase in production speed, and a yearly reduction of 43 tonnes of CO₂ emissions.

The whole process was complex, costly, and time-consuming. Now, thanks to intrusive reflow, through-hole connectors can be placed using the same machines that install SMT parts. Raspberry Pi perfected the method after several trials, adjusting the solder paste stencil and refining the PCB layout until the company’s quality standards were met.

The improvements led to a 50 percent reduction in product returns, a 15 percent increase in production speed, and a yearly reduction of 43 tonnes of CO₂ emissions. Raspberry Pi’s manufacturing now requires less machinery and inventory, with no production line interruptions due to work-in-process inventory.

Raspberry Pi says that intrusive reflow soldering was key to eliminating “wasteful” intermediate steps in the manufacturing process. The company now highlights its reduced environmental impact and improved efficiency, which align with its ongoing efforts to become a more responsible and sustainable organization.
