Full platform integration
Select your devkit, run your game directly from Superluminal, and capture performance data — it all works exactly as you would expect.
The sampling frequency on Xbox is even higher than on Windows: Superluminal supports capturing performance data up to 10 kHz.

With Superluminal we can easily attach to remote kits and quickly access and navigate an overview of the game frame even with very long captures. We can locate hotspots in the code and analyse if there are any stalls between threads without any code modifications. This has been proven exceptionally useful when analysing third party libraries and instrumentation is not an option!
Made for real world workflows; a tool you’ll actually enjoy using.
Get a visual breakdown of exactly what’s happening in your application. Easily identify bottlenecks across multiple threads, see the interactions and drill down all the way to the instruction level in real time, using one seamless UI.
Unlike other profilers that dump raw data tables, our interface is designed to show you the information you need, when you need it, in a way that actually makes sense.

Finally, a profiler that won’t let you down.
Superluminal has been engineered from the ground up for performance and stability, at scale. When other profilers choke and crash under pressure, Superluminal keeps going.
Thousands of threads? No problem. Hundreds of gigs of data? We’ve got you. Superluminal is proven to deliver even on hours long captures and the most complex codebases.

And many more features
Visual UI
Sampling data is displayed on a per-thread timeline, allowing you to see what function is being called when, in what order, & what other functions are being called around it.
Multithreading analysis
These complex interactions are visualized in an intuitive interactive interface, allowing you to inspect blocking and unblocking callstacks.
High frequency sampling
High frequency sampling (8 – 40 kHz, depending on platform) allows you to hit the ground running without the need to make any code modifications.
Source & Disassembly
A mixed-mode disassembly view lets you view per-instruction timing information. If no source code is available, the disassembly is displayed.
Filtering
Superluminal is capable of isolating a specific portion of a capture. Investigate unexpected frame spikes, or zoom in to the startup phase of your application.

Superluminal is great.
Its UI is really simple & quickly allows you to go from overview, thread interactions, PC samples, to source and disassembly. We fixed many performance issues, including ones we didn’t even know we had.
An utter joy to use.
I went from download to profiling in five minutes. An hour later, several embarrassing performance issues were made painfully obvious. After just four days, I got our frame-time down from 50 to 20 milliseconds.
It just works.
Seriously cannot recommend Superluminal profiler enough. It Just Works™ Case: VS locks up on project open for 2 minutes. Traced it, could instantly see where the problem was, and 5 min later, found the offending process. End to end, 7 min for what historically took ~2hrs.
Getting access
Getting access is quick & painless! You’ll first need to verify your Xbox developer status by following these instructions. Once verified, Superluminal will automatically install the Xbox support for you.
