Linux Graphics Debugger 2.3 - New Features

Graphics Debugger Range Profiler

Pixel History showing attribute changes by contributing draw calls

Vulkan 1.0 support for the GPU Frame Debugger
Pixel History allows you to analyze every event that contributes to the final rendered pixel
Range Profiler performance and accuracy enhancements, providing improved instant GPU throughput analysis
Volta GPU support for the GPU Frame Debugger, Performance Dashboard, and Range Profiler
Centos 7.4 support added

Visualize draw call batching efficiency using the new Batch Histogram View
View query object results and conditional rendering results in the API Inspector View
Enhanced visual experience with new Color Theme and timeline unit selection support
Improved Frame Capture Serialization with new options
New Insert Clear command on the Target View helps visually isolate the event actions that follow
Visualize host or client side memory modifications in the Events view
Logging of all unsupported functions encountered
Improved shader performance when large amount of sampler and uniforms are used
More robust remote debugging with improved SSH connection

Support for Fedora 25 (x64 only)
Fixes:
- Deadlock when debugging multithreaded rendering applications
- Crash when UE4 applications exit
- Bug when “Null fragment test” when program pipeline is used
- Issues with “Linked Programs View”

Frame debugging and profiling can be done on the latest Pascal family of GPUs (Requires a Linux driver version > 370.00)
The Range Profiler is a powerful new view for determining how your application utilizes the GPU
- All new performance library for improved GPU instrumentation as well as collection speed and accuracy
- Improved data mining allowing the user to construct ranges from sections of the scene based on predefined or user-defined criteria
- Elapsed GPU time is reported for each range, as well as hardware statistics detailing how efficiently the GPU was used
Added new Disable Depth Test and Disable Cull Face performance tests
Better support for GL_ARB_draw_indirect, GL_ARB_multi_draw_indirect, and other extensions
Improved Resources View UI, including side by side selection and resource inspection
Improved the Geometry View with powerful visualization capabilities and automated detection of vertex buffer data errors
Added Issues column to the Events View to point out potential bugs and performance issues, correlated to the event stream
Frame Debugger now has a Capture Next Frame feature to help track down intermittent issues
Users can now retry capture if unsupported OpenGL operations are encountered
