Hardware & Chips
Official DLSS 5 running on unsupported games delivers up to 90% better performance than the leaked version
Tom's Hardware- Nvidia's latest DLSS Neural Renderer, extracted from NBA 2K27, is being tested on games that do not officially support it.
- Testers report up to a 90% performance gain over the previous NR model.
- Per the headline, Nvidia says the new NR model uses 20% less VRAM and processes neural workloads up to 2x faster.
Linux 7.4 Features Very Exciting With Radeon HDMI 2.1 By Default, AMD PerfOpt, Apple M4
Phoronix- Linux 7.3 is expected to ship as stable today, which opens the Linux 7.4 merge window.
- Phoronix previews 7.4 changes including Radeon HDMI 2.1 enabled by default, AMD PerfOpt and Apple M4 support.
Servo Gets CSS Grid Working, Threadboost Offering Big Speed-Ups
Phoronix- Servo's August status report is out, following the recent Servo 0.6 release that includes the Servoshell demo browser.
- The Rust-based browser engine now has CSS Grid working, and Threadboost is credited with big speed-ups.
Synchronous Queues For VirtIO-FS Show Huge Performance Potential
Phoronix- Pending code would let VirtIO-FS use synchronous queues rather than always being asynchronous.
- VirtIO-FS is the shared file-system for moving data between guest VMs and the host, and early results show promising performance.
MeshXFS: AI Adapts XFS Into A Clustered File-System
Phoronix- MeshXFS is a clustered open-source file-system whose authors say no human wrote any of its code.
- Claude Opus was tasked with adapting the XFS file-system driver into a clustered design.
- Phoronix notes that entrusting data to an AI-created file-system will give some readers pause.
Research & Papers
Researchers train AI to detect concealed handguns using Wi-Fi signals
Tom's Hardware- WiFireNet detects concealed handguns from Wi-Fi channel-state information, with no cameras or metal detectors.
- It reached 72.5% average precision in controlled indoor tests and works on the older 802.11a standard by analyzing how weapons distort wireless signals.
Industry & HPC
300-plus local data center bans have only delayed just three US projects
Tom's Hardware- SemiAnalysis mapped more than 300 local data center moratoriums against the US pipeline.
- It found only three projects actually delayed: about 2.3 GW held up versus 38 GW expected online in 2027, per the headline.
