Arm Performance Studio vs Orx

Arm Performance Studio is a free profiling suite for applications running on devices with Arm CPUs and GPUs. Streamline records CPU, GPU, and application activity from a device, and Performance Advisor turns those captures into reports highlighting potential problems and optimization advice. Frame Advisor examines API calls and rendering data for a problem frame and provides geometry metrics. Mali Offline Compiler estimates shader and compute-kernel performance across Arm GPUs, including register usage, cycle cost, and stage-specific recommendations. The suite also includes RenderDoc for Arm GPUs, an Arm fork of the graphics API debugger with support for Arm GPU extensions and Android features. Tools can run without a graphical interface in continuous-integration workflows and export machine-readable data for custom reporting; Unity and Godot integrations can add application markers or counters. The product describes profiling Android and Linux applications and lists Android 11 or later for Streamline, Performance Advisor, Frame Advisor, and RenderDoc for Arm GPUs. Graphics profiling supports Mali GPUs from the Mali-T700 series onward, but not Mali-400 or Mali-T600 products. Community support is provided through Arm’s Gaming, Graphics, and VR forum.

Orx is a free, open-source 2.5D game development engine for C and C++ programmers. Its templated, data-driven configuration can define objects and scenes, and changes can be made without recompiling. The engine includes accelerated rendering, sprite batching, multiple cameras and viewports, custom shaders, off-screen rendering, and multiple render targets. Audio capabilities include 3D sound and music, recording, filters, and controls for volume, pitch, and stereo balance. Orx also provides collision handling, rigid-body physics with joints, and input for keyboard, joystick, mouse, and touch. Data-driven animation graphs and event management cover clocks, effects, input, physics, shaders, sound, spawners, and timelines. Localization can select language-specific images, text, and sounds while a game runs. A plugin architecture supports customization and porting. Target platforms include Windows, Linux, macOS, Web/HTML5, Android, and iOS. The zlib license permits free use and modification in freeware and commercial projects. Learning resources include tutorials, examples, setup and beginner guides, and configuration information.
