Performance issues in PostgreSQL can arise as databases grow, leading to declines in query performance. To identify problematic queries, one can log long-running queries by setting the `log_min_duration_statement` parameter in the `postgresql.conf` file. The `pg_stat_statements` module can be enabled to monitor execution statistics of SQL statements, providing insights into query performance, including execution time and the number of calls. Queries with high standard deviation in execution time may indicate inconsistency, while sorting query statistics by total execution time can reveal excessive load from multiple fast queries. Real-time monitoring can be done using the `pg_stat_activity` view to check active queries and their states, and the `pg_locks` view can help identify blocked processes. The `EXPLAIN` command can analyze query execution plans, and using the `auto_explain` module can log plans for slow queries. Understanding cost parameters in query plans helps in optimizing performance, and different join methods (Nested Loop, Merge Join, Hash Join) have varying complexities and costs. To influence the planner's choice of scanning methods, configuration parameters can be adjusted, such as disabling sequential scanning. Extensions like `sr_plan`, `pg_hint_plan`, and `AQO` can further optimize query execution. Monitoring query progress can be done using dynamic views like `pg_stat_progress_*` for various commands.

Nvidia's Deep Learning Super Sampling (DLSS) was introduced in 2018 with the GeForce RTX 20-series graphics cards and has evolved into its fourth iteration, becoming a standard expectation for modern PC games. DLSS enhances gameplay by upscaling lower-resolution images, improving frame rates, and enabling advanced graphical effects without sacrificing performance. The latest version, DLSS 4, debuted with the GeForce RTX 50-series in 2025 and features a new transformer model to enhance image quality. DLSS includes Frame Generation, which creates additional frames to improve gameplay fluidity, and Multi-Frame Generation, which can produce up to three additional frames per real frame. DLSS significantly reduces the performance impact of ray tracing, allowing gamers to enjoy high-quality graphics without compromising frame rates. Over 500 games and applications currently support DLSS technology.

The game was released on March 28, 2025, and received a warm community response, though it drew comparisons to a scaled-down version of GTA. It was quickly pirated on various torrent platforms. The developers initially used the Denuvo anti-piracy system but removed it after criticism regarding its negative impact on game performance and restrictions on modding. Players reported that Denuvo hindered performance and limited user-generated mods, essential for the game's longevity. In response to these challenges, inZOI Studio and Krafton focused on community support, leading to modders releasing enhancements. The game featured unexpected mechanics, such as fighting NPCs, kidnapping children, and running over pedestrians, prompting comparisons to GTA. The development team has since addressed some of these mechanics and bugs.
