Windows Server 2025 now supports native NVMe I/O, moving away from SCSI bus commands. This feature requires a registry key modification or group policy MSI to activate. Users can see performance improvements of up to 80% in IOPS and a 45% reduction in CPU utilization during high I/O loads. Testing on a two-socket Intel system with 208 logical cores and a Solidigm D7-PS1010 SSD showed a 45% increase in IOPS with one thread, 78% with eight threads, and 71% with 16 threads, alongside a 41% and 47% decrease in CPU load during 4K random reads with eight and 16 threads, respectively. The I/O processing workflow has been redesigned for better performance, enhancing overall latency and responsiveness. Community feedback is mixed, with some users experiencing negligible differences and others suggesting that only PCIe 5.0 NVMe devices can fully utilize the new I/O stack. There is no timeline for this feature's rollout to Windows 11, and its effectiveness may vary based on drive firmware quality. Home computing tasks may not see significant improvements, but multitasking and gaming experiences could benefit from reduced CPU load and improved system responsiveness.

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.

Microsoft has introduced native NVMe SSD support in Windows Server 2025 as an opt-in feature, marking a significant advancement 12 years after NVMe's inception. This new support allows direct multi-queue access to hardware, delivering up to 3.3 million IOPS on PCIe Gen 5 SSDs and over 10 million IOPS on Host Bus Adapters, while significantly reducing latency. The previous reliance on converting NVMe commands to SCSI commands caused processing latency and overhead. Native NVMe support eliminates outdated translation layers, enhances CPU utilization, and unlocks next-generation storage capabilities. Microsoft has set up an email address, nativenvme@microsoft.com, for user feedback and inquiries. There is no current information on the timeline for native NVMe support in Windows 11.

The PostgreSQL-compatible edition of Aurora Serverless is now generally available, allowing users to create database instances that operate only when necessary and automatically adjust capacity based on demand. Customers are billed on a per-second basis for active database capacity and standard Aurora storage costs. Users can specify minimum and maximum capacity when creating a database, and the architecture separates storage from computational resources, allowing automatic scaling from a minimum of 10GB to a maximum of 64 TB. Aurora Serverless PostgreSQL is accessible in regions including US East (N. Virginia and Ohio), US West (Oregon), EU (Ireland), and Asia Pacific (Tokyo).

Capcom is facing ongoing challenges with the PC performance of Monster Hunter Wilds, despite multiple patches aimed at improving framerate stability. The company has committed to providing performance and stability updates until at least Winter 2025, with significant improvements expected by then. Game director Yuya Tokuda announced that the upcoming version 1.021 update will not include major performance enhancements, while the Title Update 4, scheduled between November and January, will focus on reducing CPU load. This is part of a two-phase optimization plan that will also address GPU load in future patches. Despite minor improvements, the game still struggles to perform well on high-end graphics cards, and previous solutions have been seen as ineffective. Tokuda suggested that players may need to adjust their graphics settings to better manage frame rates based on their hardware capabilities.

Valve has released an update to the Steam Client that includes a performance monitoring overlay for enhanced gaming experience. This overlay provides comprehensive analysis of game performance, displaying FPS values and differentiating between frames generated by technologies like Deep Learning Super Sampling (DLSS) and FidelityFX Super Resolution (FSR). Players can select from four monitoring levels: Single FPS Value, FPS Details, CPU & GPU Utilization, and FPS, CPU, GPU, and RAM. The overlay shows minimum and maximum frame values, graphical representation of frame rates, and insights into CPU, GPU, and memory usage. It appears at the bottom of the screen and can be customized in real-time for color saturation, text size, and background opacity. Users can visualize CPU utilization per core and track FPS trends. To activate the overlay, users navigate to Settings > In Game and adjust the Performance Overlay section, where they can reposition it and assign a hotkey. Valve plans to enhance the overlay with additional data to identify hardware performance issues and provide a broader summary of game performance.
