Orx vs Tracy Profiler

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.

Tracy Profiler is a remote profiler for games and other applications, built to capture telemetry in real time at nanosecond resolution. It combines CPU profiling with frame and sampling analysis, and supports C, C++, Lua, Python and Fortran integrations. GPU profiling covers OpenGL, Vulkan, Direct3D 11/12, Metal, OpenCL, CUDA and WebGPU. Tracy can also capture memory allocations, locks and context switches, and associate screenshots with recorded frames. A capture daemon can find Tracy clients over UDP and save each capture to a separate file; a separate tool merges multi-process traces. Merging preserves zones, messages and plots, but drops GPU zones, memory events and call stacks. Sampling can heuristically reconstruct zone call stacks. An optional assistant analyzes captured data with llama.cpp models and requires local setup. Tracy is free under the 3-clause BSD license. Platforms include Windows, Linux, macOS, Android, iOS and other listed environments; releases include PDF documentation and compiled Windows x64 binaries.
