How to Fix Minecraft Lag and Stuttering on PC and Mac in 2026

Experiencing a freeze in Minecraft Java Edition can be frustrating due to the game's demands on computer performance, which can lead to lag spikes, stuttering, and low FPS. Performance issues can often be resolved without new hardware by optimizing settings on Windows and macOS. To address lag, identify the type of lag and adjust settings one at a time, starting with visuals and add-ons, then moving to memory, Java, drivers, and multiplayer servers. Quick fixes include closing background apps, restarting Minecraft, testing in a single-player world, disabling shaders, using default resources, and lowering render distance. Different types of lag include low FPS, stuttering from world loading, network or multiplayer server lag, and performance drops after enabling visual add-ons. To diagnose lag, symptoms should be matched with potential causes and fixes, such as adjusting video settings or checking server performance. Common issues include low FPS, stuttering while exploring, FPS drops when shaders are enabled, resource pack hitching, and problems with memory allocation or incompatible Java versions. Each issue has specific symptoms, causes, and recommended fixes, such as adjusting render distance, disabling shaders, or ensuring the correct Java version is used. Platform-specific fixes for macOS and Windows involve updating drivers, managing graphics settings, and ensuring proper memory allocation. Configuration mistakes can hinder performance improvements, and hardware limitations may also play a role in lag. For ongoing issues, gathering relevant logs and system details is essential for seeking help, and preventative tips include maintaining a clean test profile, gradually adding mods, and matching versions carefully.

Permanently disable Microsoft’s hidden tracker on all Windows 11 versions with this script

Microsoft's Global Device Identifier (GDID) is an internal marker that uniquely identifies each Windows installation across Microsoft services. It is a persistent device-level identifier that remains constant across supported services, and there is no option to disable or regenerate it manually. Windscribe has developed a free utility called deGDID to permanently remove the GDID from Windows systems and prevent its recreation. This tool operates by blocking Microsoft registration pathways and wiping local GDID-related states without altering system files. While it can remove the GDID from the local system, it cannot erase historical records linked to the device. Windscribe provides instructions for using the tool, which is compatible with Windows 10 version 22H2 and all versions of Windows 11 from 21H2 to 25H2. Users should be aware that disabling GDID generation may impact Microsoft services that rely on device identification, but the tool includes an undo feature to revert changes.

Generating Referentially Consistent Synthetic Test Data for PostgreSQL in .NET Application Modernization

Satyajit Gokhale, Aiswaryaa Venugopalan, Ruchi Agarwal, Nits Jeganathan, Khurram Khawaja, Vijay Mandadi, and Luke Huan contributed to this article. AWS Transform offers a .NET application modernization service that allows enterprise customers to migrate from Microsoft SQL Server to Amazon Aurora PostgreSQL Compatible Edition. This migration reduces licensing costs and enhances scalability while utilizing an open-source ecosystem. Schema conversion tools can assist in translating DDL to PostgreSQL-compatible definitions, but correctness must be verified by teams to ensure performance under real-world workloads. Traditional testing methods, such as using production data or manual checks, are not scalable and raise privacy concerns. Therefore, there is a need for realistic synthetic data generated at scale that adheres to the migrated schema's constraints. AWS Transform for SQL Server modernization employs an AI agent to generate constraint-respecting synthetic data at scale during the migration workflow. This process involves loading the PostgreSQL schema into a live database, constructing a dependency graph for data generation, and distributing tasks across multiple sub-agents. The agent validates each generated INSERT against the live database, ensuring compliance with constraints and providing error diagnostics for any violations. The synthetic data generation workflow consists of four stages: schema analysis, establishing generation order, distributing tasks across sub-agents, and validation with error recovery. The agent extracts metadata from the PostgreSQL schema, determines a valid table generation sequence, parallelizes data generation while maintaining referential integrity, and generates and validates data row-by-row against the live database. Each successful insertion enriches the context for subsequent generations, while errors are handled through structured diagnostics and iterative regeneration. The process ensures referential integrity and preserves the generation state, allowing for recovery from interruptions without data loss.

Persistent Telemetry: Permanent Microsoft Windows Identifier

Discussions about consumer privacy in the Windows ecosystem have focused on optional diagnostic settings and telemetry controls. Recently, the Global Device Identifier (GDID), a permanent device-level token embedded in the Windows operating system, was revealed in a U.S. Department of Justice complaint related to a cybercriminal investigation. The GDID uniquely identifies a Windows installation and is used by Microsoft services. It is generated when a device is linked to a Microsoft account and resides in the Windows registry, being included in data sent to remote servers. There is no option to disable or delete the GDID, and attempts to do so can disrupt essential features. This has led privacy-conscious users to consider alternatives like Linux, which offers more control over data and does not require persistent identifiers. For Windows users, strategies to minimize data linked to the GDID include using local accounts, disabling optional diagnostics, and reviewing cloud app sync settings. Privacy advocates are calling for better user controls and opt-out mechanisms for hardware tracking tokens.

Что такое троттлинг и как понять, что провайдер намеренно замедляет ваш трафик

Throttling is the intentional limitation of speed for specific types of traffic, services, protocols, devices, or users. It can occur due to various reasons, such as exceeding data caps, prioritization of certain services, load management during peak hours, or technical policies in networks. Users may experience speed drops that are selective to specific traffic types, indicating potential throttling, while universal slowdowns suggest network overload or outages. Speed tests measure connectivity to specific servers and may not reflect actual download speeds across different paths. Signs of potential throttling include isolated speed drops, consistent slowdowns at specific times, and discrepancies between speed tests and real-world performance. Initial checks should rule out home network issues, and practical diagnostics can help identify throttling by comparing speeds across different servers, types of downloads, and times of day. If throttling is confirmed and support does not resolve the issue, exploring alternative ISPs may be necessary.
