How to Profile Modern PC Games with NVIDIA Nsight Graphics

Performance analysis in PC gaming has become more complex with the introduction of DirectX 12 and Vulkan, incorporating technologies like asynchronous compute, hardware ray tracing, and machine learning-assisted denoising. Understanding GPU performance requires advanced tools to analyze workload distribution and shader behavior, with NVIDIA Nsight Graphics being a key resource. NVIDIA Nsight Graphics is a graphics debugger and profiler for modern graphics APIs, featuring the GPU Trace Profiler, which provides detailed insights into GPU execution and performance bottlenecks. Recent updates have improved its utility, including a Flame Graph for the Shader Profiler and support for NVIDIA's DLSS in D3D12 applications. The Peak-Performance-Percentage analysis method focuses on identifying GPU workload constraints and optimizing utilization rather than relying on assumptions about performance bottlenecks. This methodology is applied using Nsight Graphics to analyze GPU traces from the game Cyberpunk 2077, contrasting traditional rasterization with path tracing enhanced by DLSS Ray Reconstruction. The test setup included an Intel Core i7-14700K CPU, 32 GB RAM, and an NVIDIA GeForce RTX 4090 GPU, capturing two scenarios: one with raster-only settings and another with path tracing and DLSS. The analysis revealed that the rasterized frame's most costly aspect was lighting processing, while the path-traced frame showed increased total frame cost and a hybrid workload involving rasterization, ray traversal, and AI-driven processes. Key findings indicated that modern GPU performance is heavily influenced by memory behavior rather than just shader arithmetic, with significant time spent on compute-driven lighting processing and data movement. The analysis also highlighted that ray tracing performance is constrained by memory efficiency, indicating that performance does not scale linearly with RT-core throughput.

Hoarder is what happens when a Darkwood co-creator makes a cleaning simulator: Your job is to clean the abyss and ‘no one is coming to save you’

The 2017 survival horror game Darkwood is known for its unsettling atmosphere and innovative gameplay, despite its top-down perspective. A sequel is in development by Ice-Pick Lodge, not the original creators, Acid Wizard Studio. One of the new projects from the game's co-creators is Hoarder, a cleaning simulation game where players declutter a house once occupied by a hoarder. The game features structured gameplay with checklists and quest markers, but later introduces a challenging basement environment. The horror genre has seen increased creativity from indie studios, with titles like Iron Lung and Creature Kitchen appealing to a broader audience. Players are encouraged to add Hoarder to their Steam wishlists, though a release date has not been announced.

Death Stranding 2: On the Beach PC impressions

Death Stranding 2: On the Beach features themes of connection, grief, and the transient nature of existence, set in Australia and linked to the Chiral Network. The game is noted for its engaging gameplay and visual capabilities, with performance tests showing around 60 fps in demanding environments on high settings with an RTX 4070 Ti and Intel Core i9-12900K. Lowering settings can yield up to 94 fps, while enabling frame generation can surpass 126 fps. PICO upscaling combined with DLSS frame generation provides optimal visuals. The Steam Deck struggles with performance, achieving only 24 fps on the Portable preset. The game supports various controllers, including the Nintendo Switch 2 and DualSense, with a new difficulty mode called "to the wilder" that increases challenge through tougher enemies and resource management.

Replicate spatial data using AWS DMS and Amazon RDS for PostgreSQL

The process of migrating spatial data from self-managed PostgreSQL, Amazon RDS for PostgreSQL, or Amazon Aurora PostgreSQL-Compatible Edition to Amazon RDS for PostgreSQL or Amazon Aurora PostgreSQL-Compatible Edition using AWS Database Migration Service (AWS DMS) is outlined. Spatial data includes points, lines, polygons, and collections of these features, which are essential for applications like mapping and asset tracking. AWS DMS treats spatial columns as large objects (LOBs) and requires proper configuration for LOB handling and PostGIS support to avoid migration failures. PostGIS is an extension for PostgreSQL that manages geospatial data types and functions, enabling operations such as radius searches and distance calculations. Amazon RDS for PostgreSQL fully integrates with PostGIS, making it suitable for geospatial applications. The migration solution involves ensuring compatibility of PostGIS versions between source and target databases, configuring AWS DMS, and validating the migration. Prerequisites include having an AWS account, RDS instances for source and target, a DMS replication instance, and the PostGIS extension installed on both databases. Tables must have primary or unique key constraints, and geometry columns must be nullable for LOB handling. Best practices for configuring PostGIS include validating version compatibility, monitoring resource usage, and establishing backup strategies. Implementation steps involve creating a spatial table in the source database, preparing the target database, configuring the AWS DMS task with specific settings, and monitoring the migration process through CloudWatch logs. Common errors during replication may relate to LOB handling or PostGIS data types. Post-migration validation includes comparing row counts, verifying geometry data types, and ensuring the functionality of PostGIS spatial functions. Finally, it is recommended to clean up all resources post-migration to avoid ongoing charges.

Just when you think there’s no room for shooters to innovate, here’s one where your health is literally your framerate

FPS Quest links player health to framerate, causing framerate drops as the character takes damage. Players can upgrade weapons and manipulate the game environment to boost framerate and health, such as replacing a 3D gun with a 2D sprite or altering level geometry. One upgrade can increase framerate by 10 fps at the cost of removing structural columns, which eliminates cover. This mechanic encourages a balance between alterations and game stability.

Sektori developer says the response to his Geometry Wars-inspired roguelike has been ‘awesome’, but the game’s sales still leave him ‘with zero salary for 4.5 years’

Sektori, a game released in 2025, has achieved a 97% positive rating on Steam and features Geometry Wars-inspired roguelike mechanics. Developer Kimmo Lahtinen noted the game's unexpected success among a niche audience and highlighted the challenges of achieving commercial success in a competitive market. He observed a disconnect between lengthy game development cycles and the short attention spans of modern users, leading to a trend of quicker, smaller projects. Lahtinen humorously pointed out that the majority of Sektori's players are older gamers, indicating a generational divide in gaming preferences. The game's design philosophy intentionally limits explanations of mechanics to encourage player exploration, although some players expressed a desire for more clarity. Lahtinen is currently working on a patch to address minor issues, including a difficulty spike during the first boss battle.

This roguelike take on Geometry Wars is the best game I’ve played this month, and the latest to become a permanent fixture on my Steam Deck

November has seen the release of various notable games, including Sektori, developed by Kimmo Lahtinen, a former Housemarque developer. Sektori is a twin-stick shooter reminiscent of Geometry Wars, featuring a three-card upgrade system similar to Vampire Survivors. The gameplay involves controlling a ship shaped like an arrow in a dynamic arena filled with unique rogue polygon enemies. The game features vibrant visuals and an energetic soundtrack, demanding high focus from players due to its challenging mechanics. Players start with a shield that can withstand only three hits, and the arena's boundaries add to the difficulty. Collecting defeated enemies' triangles leads to blue upgrade tokens, which can be used to enhance the ship's abilities. Yellow "Evolve" tokens allow players to choose from three upgrades, adding strategic depth. The game includes eight card decks with unlockable abilities, and players can trigger "Rainbow Mode" by collecting letters to spell "MIRAGE." Boss encounters present significant challenges, with some balancing issues noted in the first boss fight. Overall, Sektori offers a rich and immersive gaming experience, quickly becoming a favorite among players.
