Optick vs Orx

Optick is a free C++ profiler for game performance analysis and optimization. Its tools include instrumentation, context-switch tracing, sampling, CPU profiling, frame-time analysis and GPU counters. Developers can integrate it with OPTICK_FRAME, OPTICK_EVENT and OPTICK_THREAD macros. Context tracing uses ETW on Windows, FTrace on Linux and DTrace on macOS; GPU profiling supports D3D12 and Vulkan on Windows, and Vulkan on Linux and macOS. Desktop build configurations are listed for Windows x64, Linux x64 and macOS x64. Optick also offers Unreal Engine 4 and Unreal Engine 5 plugins; its v1.4.0 release added Unreal Engine 5.0 support, and Android support in the core appears in v1.3.0 release notes. The configuration header can enable or disable features for particular platforms or builds, including disabling Optick in final builds. With multiple DLLs in one executable, Optick must be added to a shared dynamic library compiled with OPTICK_EXPORT; static linking will not work. The MIT license permits use, copying, modification, publication and distribution, and provides the software without warranty.

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.
