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.

‘Every Microsoft engineer got a stopwatch,’ says Windows veteran reminiscing about company’s past focus on speed — asserts that ‘everything’ was timed to ensure acceptable performance in the 1980s

Steven Sinofsky, a former president of Microsoft’s Windows Division, reflected on the coding practices at Microsoft during the 1980s, highlighting that every engineer received a stopwatch to promote efficiency. He noted that these stopwatches were used for tasks such as scroll speed, boot time, and resource management. Sinofsky stated that from 1980 to 2000, managing resource usage constituted half of software engineering. He shared a humorous anecdote about a colleague's request for a free stopwatch in 1993, which was deemed too expensive by Microsoft. In response to criticism regarding the performance of its Windows operating system, Microsoft has committed to improving performance, reducing overhead, and enhancing reliability across its services. The company aims to be more intentional about resource utilization and feature integration.

‘DLSS fundamentally makes no sense’ says Minecraft creator Notch, but actually it kinda does

Markus Persson, known as Notch, criticized Nvidia's Deep Learning Super Sampling (DLSS) technology on social media, stating that it "fundamentally makes no sense" because it uses the same hardware to run a neural network for frame generation. Community responses clarified that DLSS utilizes specialized hardware, specifically Tensor Cores, optimized for machine learning tasks. Some commentators suggested a focus on raw raster performance instead of machine learning enhancements. Nvidia's vice president, Bryan Catanzaro, emphasized the need for smarter graphics rendering approaches, arguing that brute force methods are inefficient. Current testing of DLSS and Frame Generation is being conducted by an expert named Nick, who is analyzing the GPU's workload in rendering frames. While DLSS has supporters, it also faces criticism, particularly regarding its performance on lower-spec graphics cards.

PostgreSQL cost model: estimating the cost of flushing temp buffers to disk

The project focuses on enabling temporary tables in PostgreSQL's parallel query execution by benchmarking sequential writes and reads of temporary buffers. Functions were introduced to measure buffer flush operations, and tests were conducted to estimate the cost of flushing temporary table buffer pages to disk. Findings indicate that sequential writes are about 30% slower than reads, leading to a proposed cost model. Temporary tables have limited parallel usage due to their function as relational variables and the complexity of parallel workers accessing the leader process's local state. Two enterprise PostgreSQL distributions already support parallel operations on temporary tables, and discussions on logical replication of DDL highlight the need for improved tooling for temporary tables. A significant challenge is that temporary buffer pages are local to the leader process, and if not flushed to disk, parallel workers cannot access them. A comment from 2015 suggests flushing the leader's temporary buffers to disk before parallel operations to allow workers to scan the table in parallel. However, this raises concerns about the cost of writing buffers versus the benefits of parallelism. The benchmarking toolkit includes modifications to PostgreSQL to facilitate measurement of local buffers. Two key commits added statistics infrastructure to track allocated and dirty local buffers and UI functions to manage buffer operations. The methodology involves creating a temporary table, flushing buffers, measuring I/O, and evaluating scan overhead. The tests reveal that the cost of writing a temporary table approximates the cost of a sequential page, leading to a proposed formula for flushing costs. The results show that larger buffer sizes lead to higher write overhead and increased variability. A comprehensive formula for pre-flushing temp buffers is suggested, factoring in the number of dirtied and allocated local buffers. Next steps include adding planner flags for temporary objects, implementing executor support for worker access to temporary table storage, introducing a temp-buffer flush operation, and integrating the cost model into the planner for parallel scans of temporary tables.
