Highly optimized the Source view so that it can display contents a lot faster, and speed doesn't depend on the length of your profile anymore, it's 100% scalable now
Improved support for instrumentation events in the Source view
We now have support for selecting multiple threads in the CallGraph and Function list UI, including a convenient thread selection UI that replaces the previous simple combobox. The new UI automatically organizes your threads into groups, based on thread name, so that you can easily select related threads in one go
The new thread selection UI is also used in the thread Find UI
To help with iterating on performance, the source view now caches symbol data for all functions you've clicked on. The cache will persist over sessions and recompiles, which means you can always re-visit the source view in a previous session to compare results
The installer now adds a SUPERLUMINAL_API_DIR environment variable that points to the location of the Superluminal API
Fixed issues where Superluminal would sometimes not start in maximized mode
Fix for crash in piechart when no data is available in the CallGraph
Fixed rare hang after processing a profile
Fixed crash in CallGraph
Fixed rare symbol resolving issue which could result in the source view not being populated
Based on your feedback, the start page ("New Session" tab) has been completely redesigned to allow users to effectively manage their captures and recent runs. We're excited for you to try it out! If you have any feedback, please let us know. The full list of changes would be too big to list here, but the highlights are:
The "Recent Files" UI has been reworked. It has been replaced with a new "Session Explorer", which allows you to browse & manage your previously recorded captures. Functionality includes sorting, filtering, renaming, deleting, setting per-file annotations, and much more
The "Recent Runs" UI has also been reworked. Recent runs are now grouped by application & platform. Clicking on an item in the navigation panel will show you all recent runs for that application. The new UI also allows you to give meaningful names to your runs, as well as options to delete old runs
The navigation sidebar is now much more compact if you have support for multiple platforms installed: the Run/Attach buttons are no longer duplicated per platform
All known high DPI issues on the start page have been fixed
Greatly improved the startup time of Superluminal. A number of blocking UI stalls right after startup have been fixed. Startup time is back down to a more reasonable ~2 seconds now
The source view has been greatly optimized when showing large files
The source view now has a new parser that correctly deals with nested comments, strings, etc. This fixes various bugs where, in certain files, the entire file could get highlighted as a 'comment'
Superluminal now fully supports Live++: when profiling an application that has had live edits with Live++ applied to it, Superluminal will now correctly pick up the new symbol info
Added DLL version of PerformanceAPI, which can be used in situations where you don't want to link against the library. The DLL version can be loaded at runtime and exposes a function to retrieve the API. See PerformanceAPI_capi.h for more info
The Instrumentation Timings window at the top of the session now has a much more compact display if no Instrumentation data is present in the profile. Furthermore, it now has an option to always hide the window if no Instrumentation data is present
Improved processing time of captures with many threads
Right-clicking on a tab will now show a context menu with some common options like "Show in Explorer", "Close", "Delete", etc
Double-clicking on a bar in the thread timeline will now zoom to that bar
The pie chart in the CallGraph view now shows the name of the function when hovering over a slice or the label
Added tooltip with the full function name to the 'Function' column of the CallGraph
Added "Expand All Children" option to the CallGraph context menu & toolbar
When a profile is opened on Windows that does not contain any sampling data, a warning will now be shown with an indication of likely causes and possible ways to fix the issue
Fixed crash when opening certain .etl files that had lost events due to a busy disk drive
Fixed bug in PERFORMANCEAPI_MAKE_COLOR; the B component was incorrectly used to form the final color
Full support for PlayStation® is now available at no additional charge! Getting access is easy: simply click the 'Confirm Developer Status' button next to Superluminal in the Tools & Middleware directory on DevNet or just let us know at info@superluminal.eu.
Fixed several issues when using paths with Unicode characters on them
Superluminal is now fully per-monitor DPI-aware. The UI will be scaled correctly using the Windows setting, no matter the scaling factor or monitor that is used.
When dragging the window between monitors with different DPI settings, all UI will be updated correctly
Runtime DPI changes, such as when logging in to a remote machine over RDP, are now correctly handled
The source view now has the functionality to browse to an alternate source location when the original source file path doesn't exist
The source file location in the source view will no longer disappear if the file path is too long.
The source view now always displays the source file location, even if it doesn't exist on local disk
The CallGraph now has support for filtering based on function names
The Function List now has a per-item context menu which can be used to jump to the corresponding function in the CallGraph
The context menu to hide/show columns in the CallGraph & Function List is now also enabled for the butterfly view.
Tooltips are no longer hidden behind the mouse cursor when using larger cursor sizes
Improved rendering performance
Fixed crash when using a control scheme with Omnidirectional pan
Fixed crash when cycling through find results while a timerange selection is active
Fixed crash when selecting a bar in the Instrumentation Timings window while a timerange selection is active
Fixed rare issues with starting a capture with 'start immediately' disabled
Fixed issue where the Thread Interaction tab could display the wrong blocking/unblocking stack in certain cases
Fixed issue where the UI rendering would be corrupted if the QT_SCALE_FACTOR environment variable is set
Fixed issue where the navigation pane on the start page could become too big, which would result in a window that could not be resized vertically anymore
Full support for Xbox One® and Xbox Series X® (Project Scarlett) is now available at no additional charge! Getting access is easy: just send us an email at info@superluminal.eu
PlayStation® 4 support is now available for preview. To get access, simply click the 'Confirm Developer Status' button next to Superluminal in the Tools & Middleware directory on DevNet or just let us know at info@superluminal.eu.
Fix for rare crash in threads view Fix for attach settings (including filter) not being persistent between runs.
Fix for update timer that could keep running while in 'start paused' mode
The selection mechanics have been completely reworked
The timerange is only ever set by the user. When clicking on a function, we do not automatically make a timerange selection anymore. This makes it also possible to continue clicking on functions while having an active timerange, making navigation with the callgraph a lot easier.
All views are always filtered to the active timerange. The option to choose between 'entire session/selected timerange' has been removed from all UIs. If there is no active timerange, data for the entire session is displayed.
Find results separated. The Find results are now separate from your selection. This means you can now click through/interact with your Find results without losing them.
Highlight changes.The Find result highlights are always displayed in yellow. The highlights that indicate your selection in the callgraph/function list are now always white.
We'd love to hear what you think of these changes!
Greatly reduced CPU usage of the profiler itself. It will no longer use CPU when idle
Added support for adding multiple input-bindings to a single action
The default bindings now support Alt + Mouse wheel zoom as secondary binding
Added support for pre-installing a license during install of Superluminal. This allows system administrators to remotely install and activate Superluminal without intervention from the user. To use, specify /lic=<path to license file> on the installer command line
Breaking Change The PerformanceAPI has been completely reworked. Please see the documentation (Help -> Documentation) for more information. Most important changes:
It is now a static library instead of a DLL
It is no longer required to use the InstrumentationScope class to send events to Superluminal. New functions BeginEvent and EndEvent are now available to achieve the same effect, allowing for easy integration with existing profiling systems
A FindSuperluminalAPI.cmake file is now included for easy integration in CMake-based build systems
Input bindings have become much more versatile: key and mouse bindings can now be configured to match many existing input schemes. Standard presets for commonly used profilers have been added
GPU memory consumption has been lowered a great deal
Vertical scrolling is now smooth instead of a stepwise scroll
Improved capturing UI: start/stopping/canceling profiling is now done through buttons rather than 'links'
Improved capturing UI: the progress icon is greyed out and doesn't animate when profiling is paused, to more clearly indicate the paused state
Fixed issue with symbol resolving progress bar being on 100% while symbols were still loading
Fixed go to blocking/unblocking stack not highlighting the target stack in certain cases
Fixed go to blocking/unblocking stack not highlighting the entirety of the stack in certain cases
Fixed 'F' to frame: now frames the selected timerange again
Added software rendering support for systems where GPU acceleration is not available
Added 'Flat List' view, which collapses all data for a given function into a flat view, giving you total inclusive/exclusive time per function
Added butterfly (called by/calls) view (in the 'Flat List' tab). This will show you where a particular function is being called from and what other functions it calls
Added support for resolving thunk functions in all views. This resolves various cases of calls to thunk functions missing from, for example, the disassembly view
License entry is now more forgiving; extra newlines and such are ignored
Fixed some font rendering artifacts
Fixed performance regression in symbol resolving
Fixed crash when drag selecting a timerange after switching the callgraph to 'selected timerange' in rare cases
Fixed several rare crashes that could occur right after opening a profile
Fixed corrupt display of thread states in CallGraph in certain cases
Fixed thread state distribution being incorrect in the callgraph in cases where there is a context switch without callstack
Fixed exclusive time in the callgraph being off in cases where there is a context switch without callstack
Fixed timings in the source view from diverging from timings in the threads/callgraph views in certain cases
Fixed display of files with UTF8 byte order mark in source view
Fixed rare shutdown crash when using the profiler over RDP
Fixed crash when browsing through the callgraph while two sessions are active
