Bluetooth 6.0 introduces significant improvements in latency, security, location tracking, and power efficiency, with devices like phones and headphones already adopting the new standard. However, it does not yet support lossless audio streaming, though future updates may enable high-res audio transmission. The upgrade promises better connectivity, longer battery life, and enhanced security for wireless devices.
The author has changed his view on wireless CarPlay and Android Auto, now favoring wired connections due to less battery drain, cooler phone temperatures, and reduced latency, which improve overall usability and device longevity.
NVIDIA's GeForce NOW cloud gaming service has received a major upgrade with new RTX 5080-class servers, offering significant performance improvements, support for high resolutions and frame rates, and new cinematic quality streaming features. While visual quality now closely rivals local gaming, latency remains a challenge, especially for competitive play, though the platform offers a quieter, more energy-efficient alternative to local gaming.
Despite several years of deployment, 5G has largely fallen short of its lofty promises, offering modest speed improvements, spotty coverage, and limited real-time application benefits, with many of the advanced features still in development and the technology not yet a game changer.
Digital Foundry tested the Switch 2's GameCube emulation, finding that while the games are faithfully represented, there are issues with input latency, analogue stick sensitivity, and frame drops that Nintendo needs to address for a more authentic experience.
Nintendo Switch 2's support for GameCube classics offers improved graphics and performance but introduces notable input lag (~50ms) and some emulation issues like frame drops and controller sensitivity, which may impact gameplay, especially in timing-sensitive titles like F-Zero GX.
UVA scientists have discovered that small variations in the Rev-RRE axis, crucial for HIV RNA export, significantly influence the virus's ability to replicate and reactivate from latency, offering new insights that could improve strategies to cure HIV by enhancing latency reversal approaches.
Amazon's development of an AI-powered version of Alexa faces significant challenges, including latency issues and compatibility problems with older Echo devices, according to leaked internal memos. These issues could delay the release of the new Alexa, codenamed Banyan, until 2025. The memos also reveal concerns about customer satisfaction and the limited number of Skills available at launch. Amazon aims to enhance Alexa's capabilities to compete with other tech giants in the AI space, but internal documents suggest substantial work remains to meet these goals.
Despite the recent release of Wi-Fi 7 and its promises of near-zero latency for wireless VR, the actual cause of latency in popular wireless VR is the heavy compression of frames by the GPU's video encoder and the time it takes for the decoder in the headset's chipset to decompress them. While Wi-Fi 7 may bring marginal improvements to the wireless VR experience, its theoretical maximum bandwidth is not likely to be achieved in the real world, making it insufficient for handling raw frames for high-resolution headsets. Meaningful reductions in wireless VR latency will come from improved encoders and decoders, rather than Wi-Fi 7.
The Wi-Fi Alliance has announced the launch of Wi-Fi 7 Certified products, offering "near-zero" latency for real-time applications such as wireless VR streaming. Wi-Fi 7, also known as 802.11.be, introduces features like Multi-Link Operation (MLO) and Simultaneous Transmission and Reception (STR) to support near-zero latency, benefiting wireless VR by allowing devices to connect to multiple bands simultaneously for increased throughput and reliability. While this promises significant improvements, it's important to note that Wi-Fi transmission latency is just one part of the overall latency pipeline for VR, which includes rendering, encoding, decoding, and device-dependent latency.
A new internet standard called L4S (Low Latency, Low Loss, Scalable Throughput) aims to reduce latency and improve internet speed by minimizing queuing and congestion. L4S allows packets to indicate if they have experienced congestion during their journey, enabling devices to make immediate adjustments to prevent further congestion. Companies like Apple, Google, Comcast, and Nokia have shown interest in L4S, and some cable modems already support it. While L4S is not widely deployed yet, it has the potential to significantly improve the user experience of web browsing, video streaming, and real-time applications like game streaming and VR.
Huawei has launched NearLink, a breakthrough short-range wireless connection technology that offers faster data transmission, lower latency, and longer range compared to Bluetooth. NearLink boasts 60% lower power consumption, six times higher data transmission speed, 1/30th the latency, and twice the coverage distance. It has already been integrated into Huawei's latest Mate 60 smartphone and will be part of the HarmonyOS 4 operating system. However, due to US sanctions, NearLink is unlikely to be available on American devices.
A video comparing the speed of an older computer to a modern one has sparked a debate about why modern personal computers often appear slower. The slowdown is attributed to various factors, including the use of compatibility layers that abstract software from hardware, reducing response times but increasing latency. Additionally, software companies may not adhere to best programming practices or take advantage of modern computing power to reduce costs. Modern software also requires more hardware resources for safe and secure operation compared to older equivalents.
A new study has found that HIV can lie dormant in the brain's immune cells called microglia, which act as a persistent reservoir for the virus. While current treatments can control the virus, they cannot eradicate these dormant cells, which can cause a recurrence of active disease if treatment is stopped. The breakthrough came from a research program called The Last Gift, which allowed researchers to study brain tissue samples from HIV-positive people who donated their bodies to science. The discovery opens up the possibility of finding a way to eradicate latent HIV and offer a true cure for the infection.
Sony's CEO, Kenichiro Yoshida, has warned that cloud gaming is still technically challenging, citing latency as the biggest issue. Despite Sony's early entry into the market, the promise of cloud gaming remains unfulfilled after more than a decade of development. Yoshida also pointed to the costly inefficiencies of cloud gaming where servers are idle for much of the day before having to cope with high levels of traffic during peak hours. Sony may utilize its AI agent, GT Sophy, to enhance cloud gaming.
