We tested gaming performance in 17-year-old Windows 7 against Windows 11 on a modern gaming PC — older operating system delivers advantages in some scenarios

Windows 7 was released in 2009 and has received positive reviews for nearly two decades. A performance evaluation was conducted by installing Windows 7 on a modern PC and testing it against Windows 11 across ten games, including eight DirectX 11 titles and two DirectX 9 titles. In the game Metro 2033 Redux, Windows 11 achieved a higher average frame rate, but Windows 7 had better handling of CPU-related performance drops, resulting in stronger 1% lows. In Batman: Arkham Origins, Windows 7 outperformed Windows 11 in both average frame rate and 1% lows at 1080p and 4K. For Batman: Arkham Knight, Windows 7 showed higher performance when CPU-limited at 1080p, while Windows 11 led in GPU-limited scenarios at 1440p and 4K. In Batman: Arkham City, Windows 11 had the advantage across all resolutions as the game was GPU-bound. In The Witcher 3: Wild Hunt, Windows 7 outperformed Windows 11 in 1% lows at 1080p, but Windows 11 took the lead at higher resolutions. Control showed Windows 11 outperforming Windows 7 across all resolutions due to GPU optimizations. Hitman: Absolution also favored Windows 11 in GPU-limited scenarios. For DirectX 9 games, Windows 7 demonstrated significant advantages in average frame rate and 1% lows in Batman: Arkham Asylum, especially at lower resolutions, while performance in Borderlands 2 was nearly identical across both operating systems at 4K. Overall, Windows 7 excels in CPU-limited scenarios, while Windows 11 performs better in GPU-bound situations, aided by advanced graphics drivers. Microsoft’s ongoing efforts aim to improve Windows 11's performance and reliability.

A week with Googlebooks: four notes from our testing so far

Google has launched five new Googlebook laptops featuring the Googlebook OS, which has received mixed reviews. While the hardware is praised, the software is criticized for being problematic and not a significant upgrade from ChromeOS. Users report issues such as the inability to run Chrome with separate Google accounts, clunky Android apps, and awkward command requirements for messaging apps. The app ecosystem is struggling, with many applications failing to adapt to the Googlebook's interface, resulting in a frustrating user experience. Linux applications face integration challenges, complicating multitasking. Despite some successful features like file transfer and notification responses between Googlebook and Android devices, users experience frequent connectivity issues and sluggish performance.

How and why we built Managed PostgreSQL for AI workloads

The Nebius Managed PostgreSQL team developed a solution for AI workloads using CloudNativePG and Kubernetes, resulting in improved backup and restore times by transitioning from Barman to WAL-G, reducing a 1.5 TB backup duration from over a day to two hours. Since its launch in 2025, the service supports hundreds of production clusters and manages tens of tebibytes of data. Key features include high availability, point-in-time recovery, automated failover, compressed and encrypted backups, rapid restoration, connection pooling, and strict synchronous replication for zero data loss. Kubernetes and CloudNativePG were chosen for their advantages, including out-of-the-box features and open-source distribution. Each cloud project has a separate MK8s cluster for customer isolation and security. Persistent data is stored on fault-tolerant SSD drives, enabling swift instance migration during failures. Regular physical backups are archived, allowing restoration within a seven-day window with a single click. The transition from Barman to WAL-G addressed slow backup and restoration times and resource control limitations. With WAL-G, backups and restorations for a 1.5 TB cluster improved to two hours and one hour, respectively. PgBouncer was implemented to manage database connections effectively, reducing connection storms during peak AI workload traffic. Two vector search extensions, pgvector and pgvectorscale, are available to cater to different memory and dataset needs. Benchmarking showed that Nebius performs competitively with AWS at a lower cost. The infrastructure integrates cloud engineering principles with specialized expertise to meet AI workload demands.

Microsoft’s AI-Powered Windows Strategy: 5 Things To Know

Microsoft has transitioned its Execution Containers capability into general availability, creating a secure environment for AI agents on Windows 11. Nvidia's CEO praised Microsoft's MXC architecture as a revolutionary foundation for application development. Organizations are increasingly relying on managed service providers to navigate AI tools. The general availability of Microsoft Execution Containers allows organizations to define access for AI agents, with real-time policy enforcement. The open-source MXC library integrates across Windows, macOS, and Linux, helping manage agent interactions and mitigate risks. Microsoft is enhancing the Copilot experience with hybrid intelligence features and revamping Windows Search for better performance. Preorders for new Copilot+ PCs powered by Nvidia's RTX Spark technology are open, with shipments starting on October 16. Device partners like Dell, HP, and Lenovo are also launching AI PCs on the same date. Later this year, Dell and HP will introduce Nvidia’s DGX Station technology to enable local running of frontier-class AI models on Windows devices.

Someone squeezed Windows 95 onto an ESP32-P4, and so can you

A developer has successfully run Windows 95 on an ESP32-P4 board using the tiny386 emulator. The project, initiated by GitHub user winitboonkliang, allows Windows 95 to boot from a microSD card onto the ESP32-P4's 1280×800 MIPI-DSI display, with USB keyboard and mouse support. The implementation utilizes a port of tiny386, an x86 PC emulator. This project is not intended for everyday use but serves as a study project to explore the limits of running legacy software on compact hardware. A detailed guide is available on GitHub, outlining compatibility issues and limitations.

VPN threat protection vs. dedicated antivirus: Are VPNs really enough?

Many VPN providers are now offering additional security features such as malware detection, malicious link checkers, and ad blockers, alongside their primary function of encrypting internet traffic. Notable VPNs like NordVPN and Surfshark have integrated real-time malware protection, with NordVPN becoming the first VPN to receive certification as a reliable anti-phishing tool in 2024. Surfshark's Surfshark One package offers comprehensive real-time protection from viruses and malware. Other VPNs, such as Avira and CyberGhost, utilize shared infrastructures for antivirus capabilities, which can lead to delays in updates and inconsistent platform support. Microsoft Defender has improved significantly, blocking 95.5% of live threats according to AV-Comparatives, while Apple employs multiple defenses in macOS, including Gatekeeper and XProtect, to manage malware threats. Avast Free Antivirus has achieved a perfect 100% block rate in recent testing but comes with limitations compared to paid antivirus suites like Norton 360 Deluxe and Bitdefender Total Security, which offer additional features such as password managers and identity monitoring. A layered approach to digital security, combining a VPN, free antivirus, and built-in OS-level security, is recommended for effective protection. Relying solely on one layer leaves potential gaps, as a VPN cannot detect existing malware, and free antivirus solutions may lack advanced features. Users managing sensitive data or frequent financial transactions should consider investing in premium antivirus suites for enhanced security.
