Microsoft's Outlook for Windows is facing criticism for its notification handling, particularly in the new Outlook version built on the WebView2 framework. Users experience a delay of approximately 10 seconds when clicking on email notifications, compared to the near-instantaneous access provided by Outlook Classic, which allows users to open new emails in about five seconds. The new Outlook consumes significantly more memory and CPU resources, using between 490 MB and 636 MB of RAM, while Outlook Classic operates within 117 MB to 148 MB. Despite updates aimed at improving the new Outlook, the core issue of notification handling remains unresolved. Microsoft is working on enhancements, but the performance limitations of the WebView2 architecture continue to affect user experience. Outlook Classic will continue to be supported until April 2029.

Capcom released a performance patch for Monster Hunter Wilds that has significantly improved the game's performance on PC, particularly on Steam. Users report a remarkable reduction in frametime lows, with many stating that all previous performance issues have been resolved. The patch has received a positive reception, leading to a surge in favorable reviews. Players are now able to recommend the game, with some finding optimal settings for performance on the Steam Deck. Anecdotal evidence suggests that the patch has effectively addressed prior gameplay hitching issues, resulting in smoother framerates.
A Reddit post by user de_Tylmarande claimed that purchasing downloadable content (DLC) could improve frame rates in the PC version of Monster Hunter Wilds. Testing revealed that the performance issues were due to a bug related to the game's frequent checks for DLC presence, particularly in specific hub areas. Using a mod called "Less DLC Checks," which integrates with the RE Framework modding tool, players observed significant performance improvements: 11.4% at maximum settings, 20% at high settings, and 25.6% at low settings when DLC checks were blocked. The performance hit primarily occurs near a Support Desk felyne, indicating the availability of DLC. Capcom has not officially addressed the issue, and while the narrative about DLC enhancing performance was debunked, it raises concerns about the company's quality assurance processes.
AWS has introduced Graviton4-based R8gd instances for Amazon Aurora, which offer significant performance enhancements over Graviton2-based db.r6g instances. Users can expect up to 165% higher throughput, a 120% improvement in price-performance ratio, and an 80% enhancement in application response time. The integration of an Optimized Reads-enabled tiered cache allows for expanded database caching capacity, minimizing network storage access and improving query response times. Organizations like Mindbody and Claroty have reported substantial performance improvements and cost savings after implementing these features. Aurora PostgreSQL 17 has introduced smarter storage batching algorithms and optimized writes, further enhancing performance for I/O-intensive applications. The db.r8gd instances allow for scaling up to 48xl, providing 192 vCPUs, 50 Gigabits of network bandwidth, and 10.4 TiB of local NVMe capacity. The benchmark testing using HammerDB demonstrated significant improvements in throughput, price-performance ratio, and response times when upgrading from db.r6g to db.r8gd instances. The Aurora Optimized Reads-enabled tiered cache is available for Aurora PostgreSQL versions 17.4 and higher, among others.
Recent updates to Windows 11, specifically the October security and feature patch (KB5066835), have caused frame rate drops in games, with Digital Foundry reporting significant performance issues in Assassin's Creed Shadows. Testing with an AMD Ryzen 9800X3D and Nvidia RTX 5090 showed low frame rates until a hotfix from Nvidia was applied, which improved performance from 34fps to 72fps. Without the hotfix, gamers could see a performance decline of 33% to 50%. Anecdotal evidence suggests the hotfix may also improve performance in Counter-Strike 2, with an 11% increase in 1% lows reported. Nvidia's documentation indicates the hotfix addresses issues in "some games," but further testing is needed to determine if the performance issues affect only Nvidia GPUs or also AMD graphics cards. Gamers with recent Nvidia graphics cards experiencing performance dips are advised to download the hotfix.
KB5065431 is the latest security update for Windows 11 23H2 devices, being rolled out as a reminder that this version will reach its end of life on November 11, 2025. Microsoft is migrating eligible 23H2 Home and Pro edition PCs to Windows 11 24H2, but the rollout was temporarily paused due to around a dozen reported errors, some linked to app compatibility issues. Most barriers to upgrading have now been resolved, allowing the automatic upgrade process to begin. The Enterprise and Education editions of Windows 11 23H2 have an extended support timeline until November 10, 2026. The KB5065431 update will automatically install on PCs, or users can manually install it using the offline update installer file (.msu). The Windows 11 22631.5909 build includes important fixes but no new functionalities, addressing issues like NDI streaming performance and enhancing security for SMB shares. It also introduces a UAC prompt for administrator credentials during certain operations, which can be disabled by administrators via group policy.
pg_stat_statements is a PostgreSQL extension for monitoring query statistics, tracking execution counts, execution times, and row returns. It uses a hash table to store metrics for each query, identified by a key generated from four parameters: queryid, User OID, Database OID, and a toplevel flag. The extension can become a performance hindrance in high contention environments due to locking operations on the hash table.
When numerous unique queries are executed, contention for the hash table can lead to significant performance drops. For example, with pg_stat_statements enabled, a system with 48 CPUs showed a TPS drop from 237,437 to 32,112 when executing unique queries. In contrast, with a high volume of similar queries on a 192 CPU machine, enabling pg_stat_statements resulted in a TPS of 484,338 compared to 1,015,425 with it disabled.
Query sampling is introduced as a method to mitigate performance issues by recording metrics for only a fraction of executed queries. The pg_stat_statements.sample_rate parameter allows configuration of the proportion of queries tracked. However, sampling can lead to incomplete data and potential security risks if sensitive information is recorded in non-normalized form.
Benchmark tests with varying sample_rate values showed that as the sample_rate decreased, TPS increased, and SpinDelay diminished. At a sample_rate of 1.0, TPS was lowest, while at 0.25 and below, SpinDelay effectively disappeared, indicating that sampling can significantly enhance performance under high contention conditions.
Microsoft has released new builds for Windows 11 and Windows 10 for Insiders on the Release Preview Channel, focusing on user experience improvements, especially for European Union users.
The Settings app has been updated to enhance the default app settings, allowing the “Set Default” button to automatically associate additional file and link types with the newly designated default browser, which will be pinned to the Taskbar and Start menu unless opted out. A new one-click button for browsers has also been added to simplify changing the default app for opening PDF files, addressing previous concerns about Microsoft Edge being set as the default for PDFs.
Windows 11's latest build 23H2 (22631.5545) introduces a visual preview feature in the Windows Share window, allowing users to see a representation when sharing links or web content. This update also resolves a performance issue that caused the Windows Search box to take over 10 seconds to load.
