Using Graphics Performance Analyzers
- How do I start using Graphics Performance Analyzers?
- It is pretty easy to get started with Graphics Performance Analyzers -- most game developers start using Graphics Performance Analyzers immediately after installing the package, since the tools use standard graphics drivers and do not require modifications to your game code (one exception is if you are trying to perform thread-based analysis with the Platform Analyzer, which requires that you add some code to designate individual threads). To get you up and running quickly, check out the Getting Started and Online Help, which explains how to use the product features.
- How difficult is it to learn how to use the product?
- Graphics Performance Analyzers features an intuitive user interface that does not require extensive training to quickly access key performance metrics. Therefore, many users will immediately realize many benefits of the product. However, as Graphics Performance Analyzers enable you to perform precise analysis and experiments for every portion of the rendering pipeline, users with a detailed knowledge of Microsoft* DirectX, OpenGL OpenGL ES for mobile devices can quickly utilize even these advanced features.
- What kinds of problems can Graphics Performance Analyzers find?
- If you have performance "hot spots" within your game, Graphics Performance Analyzers can help pinpoint them at the system level, at the frame or sub-frame level, or by visualizing task performance across the CPU/GPU. Once you have identified issues, try different experiments to see the resulting changes in the rendering time as well as the visual effect of these changes. The benefit is that Graphics Performance Analyzers can help improve your frame rate and/or enable you to add new visual effects, while still providing an acceptable level of user interactivity.
- How do the System Analyzer and Graphics Frame Analyzer for DirectX/OpenGL help identify optimization opportunities in my game?
System Analyzer provides access to system-wide metrics for your game, including CPU, GPU, API, and the graphics driver. The metrics available will vary depending upon your platform, but you will find a large collection of useful metrics to help quantify key aspects of your application's use of system resources. Within the System Analyzer you can also perform various "what-if" experiments to diagnose at a high level where your game's performance bottlenecks are concentrated.
If the System Analyzer finds that your game is CPU-bound, perform additional fine-tuning of your application using Platform Analyzer or one of the Intel performance optimization products such as Intel Parallel Studio or Intel VTune Amplifier XE.
If the System Analyzer finds that you game is GPU-bound, use the Graphics Frame Analyzer for DirectX/OpenGL to drill down within a single graphics frame to pinpoint specific rendering problems, such as texture bandwidth, pixel shader performance, level-of-detail issues, or other bottlenecks within the rendering pipeline.
- How does the Platform Analyzer help identify optimization opportunities in my game?
- Platform Analyzer visualizes the execution profile of the tasks in your code on the entire platform over time, on both the CPU and GPU. This helps you understand task-based issues within your game, enabling you to optimize the compute and rendering tasks across both the CPU and GPU. Platform Analyzer uses trace data collected during the application run to provide a detailed analysis of how your code executes across all threads, and correlates the CPU workload with that on the GPU.
- Though Graphics Performance Analyzers seems to be targeting game developers, will the tools work with other graphics applications?
- Graphics Performance Analyzers are primarily designed to solve the performance optimization needs of game developers, and for media application developers. However, the features of the tool suite are broad-based for use with any visual computing application. In other words, our expectation is that anyone developing graphics applications, both "expert" and "novice" alike, should be able to take advantage of the analysis and optimization capabilities of the product.
- Do I have to modify the software for my game, or install special drivers, in order to be able to use Graphics Performance Analyzers?
- System Analyzer, Graphics Frame Analyzer for DirectX, and Graphics Frame Analyzer for OpenGL can analyze your game without any code modifications or special libraries. This is possible because the tools access the CPU, driver, DirectX, and GPU metrics directly from the game environment, a big plus for common analysis tasks. For more complex, task-based analysis with the Platform Analyzer, you will benefit by inserting Instrumentation and Tracing Technology (ITT) API calls that tag the various tasks in your game code -- but you will have to do this once, as the ITT library used by Graphics Performance Analyzers is also used by a number of other Intel performance analysis tools.
- What are the Graphics Performance Analyzers system requirements?
- As the specific requirements depend both upon your target platform and analysis platform, read the Intel GPA Release Notes and Intel System Studio Release Notes for a breakdown of supported third-party devices and individual tool capabilities on those devices. When using Graphics Performance Analyzers in the client/target mode, the minimum requirements of the client system used to analyze either Windows or Android workloads are: Intel Core Processor with a minimum of 2GB of memory, though at least 4GB of memory and a 64-bit OS are highly recommended. When analyzing and taking frame captures of workloads on Android* devices, the target should have a minimum of 1GB system memory. More memory may be required for more complex OpenGL ES* 2.X/3.1 workloads.
- Do Graphics Performance Analyzers work with netbook computers and Intel Ultrabooks™?
- Yes, the tool suite supports many popular netbook computers and Ultrabook systems. However, lower end systems may not have sufficient resources to run the tools. So if you encounter issues when running System Analyzer HUD or Graphics Frame Analyzer, use the client/target ("networked") version of these tools with a more powerful client system. A good suggestion for a client system would be a computer running a 64-bit OS with greater than 4GB of memory.
- Are Graphics Performance Analyzers supported on Windows 32-bit platforms?
- The provided support is limited. Frame and trace captures taken on 32-bit Windows* OS can be opened remotely from Graphics Frame Analyzer installed on a 64-bit Window* OS platform. For more information, see Graphics Performance Analyzers: Analyzing Windows* Applications Running on 32-bit Target Systems.
- Do I need to "root" my device to analyze Android workloads with Graphics Performance Analyzers tools?
- I can't analyze my Android* applications by Graphics Performance Analyzers. Do I need to build my apk with any special settings?
Yes: If the application you want to analyze appears in the Non-analyzable applications list, modify the application permissions as follows:
- Open the AndroidManifest.xml file of your application.
- Enable the Internet connection permission.
- Enable the debuggable permission.
- Rebuild the application package and restart the System Analyzer. The application appears in the Analyzable applications list and can now be analyzed. For details, see the Preparing Android Applications for Analysis section at http://software.intel.com/en-us/articles/intel-gpa-online-help-win.
