To do this, use needsToDrawRect: or getRectsBeingDrawn:count: to identify the specific area to update, and pass the result to drawRect:. Analyze the profiling and performance data to find heavily used functions that can be optimized.Display Device Performance Profile Analysis 12. If you want to change your language preference later, use the language menu at the bottom of each page. Press Command-2 to show record settings in the inspector pane. this contact form

You can use the DispPerf tool to create a performance profile for your platform's display system. Reduce the use of opacity, such as in views that exhibit a translucent blur. It allows you to quickly see where your app renders fewer frames than expected.

You’ll be auto redirected in 1 second. Copy // Performance Logging Type if (pBltParms->pBlt != EmulatedBlt) { DispPerfType(DISPPERF_ACCEL_HARDWARE); } When the blit operation completes, the BltComplete function stops profiling with a call to the DispPerfEnd function. Copy Dispperf –cwwwwwd Dispperf calls the CreateWindow function five times, profiling the performance of the display functions. In the profiling template selection dialog that appears, click Time Profiler.

Clear the checkboxes for the other cloneable libraries, then choose OK. Change Language Not Now This class requires API level or higher This doc is hidden because your selected API level for the documentation is . Windows 7, 32-bit – Driver version needed (347.74) Windows 7, 64-bit – Driver version needed (368.39) Windows 10, 64-bit – Driver version needed (368.39) To access older versions of NVIDIA PerfKit, When ProfApp.exe is finished, it writes a message similar to this in the debug output: Copy ProfApp: Took 34297 ms to perform blts.

If the operation is not supported directly by the graphics hardware, the driver tries to find a function among the BitBlT emulation library functions to handle the operation. To learn how the environment variable causes the correct compiler directives to be set, see the Sources file for the ATI driver. On the device, press the F12 key to stop profiling.

Each of these pieces of hardware has constraints; pushing or exceeding those constraints causes your app to be slow, have bad display performance, or exhaust the battery. PC packages includes support for 32-bit and 64-bit Windows 10, Windows 8, Windows 7, and Vista platforms.

  1. Correlate Interactions with Results After capturing data with the Core Animation instrument, you may see spikes in the timeline pane where the frame rate of the app becomes appreciably better.
  2. To discover what causes your specific performance problems, you need to take a look under the hood, use tools to collect data about your app execution behavior, surface that data as

Cloning a Catalog Item 3. Use the CPU strategy usage view to compare core usage over given time periods. PerfWorks is the successor to NVIDIA’s Perfkit.

Note: While profiling an app, you should disable Instant Run.

When reviewing the results from DispPerf, also look for functions that inherently use large amounts of CPU time, such as WaitForNotBusy.

Multiple view layers that are drawn on top of each other with blending enabled are highlighted in red. Look for unbalanced core usage. Build a release configuration for your run-time image. Check This Out The detail pane shows the frame rate for each recorded sample.

To measure times accurately, DispPerf can be used only on run-time images that support QueryPerformanceCounter and QueryPerformanceFrequency with a recommended resolution of 1 microsecond. Look for Performance Bottlenecks Performance monitor counters (PMCs) are hardware registers that measure events occurring in the processor. When the build is complete, configure your download and debugging connections. On your Platform Builder workstation, open the file %_FLATRELEASEDIR%\DispPerf_Results.csv with a spreadsheet application to review the profiling results for your display driver.

OK, make this page visible Take a one-minute survey? All drivers in the %_WINCEROOT%\Public\Common\OAK\Drivers\Display tree demonstrate how to use the profiler for measuring performance of blits and line drawing. Do not use the Core Animation instrument to measure OpenGL ES performance. The following code example shows how DispPerf clears its buffer of all profiling information.
