ReviANGLE

A drop-in opengl32.dll proxy that routes Geometry Dash's OpenGL through Google ANGLE → DirectX 11.

Unlock FPS, reduce input lag, eliminate microstutters — all on hardware Geometry Dash never officially targeted.

What is it?

ReviANGLE is a performance mod for Geometry Dash 2.2 that replaces the game's opengl32.dll with a custom proxy. The proxy:

  1. Translates OpenGL → DirectX 11 via Google ANGLE.
  2. Adds 84 low-level performance modules that hook into ANGLE's hot path:
    • GL state deduplication (skip 30-50 % of redundant cocos2d-x calls)
    • High-resolution frame pacing (no CPU spin)
    • ANGLE mutex stripping (+6-12 % CPU gain)
    • P-core pinning (no E-core migration on hybrid CPUs)
    • VRAM reservation against texture eviction
    • NVAPI driver profile (PSTATE=P0, max-perf, no driver vsync)
    • Windows Power Throttling killswitch
    • 75+ other tweaks — see docs/CONFIG_REFERENCE.md
  3. Ships with a standalone GUI configurator with bilingual (EN/RU) descriptions for every option.

Why?

Vanilla GD was written for OpenGL on hardware that's now 15+ years old. On low-end systems (laptops with integrated graphics or older GPUs) it stutters, caps at 60 FPS, and wastes huge amounts of CPU on redundant driver calls. ReviANGLE rewrites that pipeline.

Quick install

  1. Go to Releases and download ReviANGLE-vX.Y.Z-win64.zip.
  2. Backup your Geometry Dash folder (or at least the original opengl32.dll if it exists).
  3. Extract the ZIP into your Geometry Dash install directory (where GeometryDash.exe lives). You should now have: 
    Geometry Dash/
├── GeometryDash.exe
├── opengl32.dll              ← from ReviANGLE
├── libEGL.dll                ← from ReviANGLE (ANGLE)
├── libGLESv2.dll             ← from ReviANGLE (ANGLE)
├── d3dcompiler_47.dll        ← from ReviANGLE (ANGLE)
├── angle_config.ini          ← config (editable)
└── gd-angle-editor.exe       ← optional GUI configurator
  4. Launch GD. If everything works, angle_log.txt will appear next to the .exe.

Configure

Run gd-angle-editor.exe for a GUI:

  • Bilingual descriptions (English + Russian) for every option
  • Enum dropdowns where applicable (e.g. backend = d3d11 / d3d9 / vulkan)
  • Comments and section structure preserved on save (round-trip safe)
  • One-click "Reset to defaults" applies the best-feel preset for the tested hardware

Or edit angle_config.ini directly — it's plain text with full bilingual comments.

Performance numbers

Measured on the tested hardware, average over 10 runs of the same hard demon (Acu):

Build Avg FPS 1 % Low Frame-time variance
Vanilla GD 2.2 88 41 high (visible micro-stutter)
ReviANGLE 2.0.0 156 (+77 %) 121 (+195 %) very low

FPS uncapped (unlock_fps_cap=true), pacer at frame_pacing_target=120. Your numbers will differ — these are reference figures from the tested system.

Building from source

See docs/BUILDING.md. TL;DR:

# Prerequisites: Visual Studio 2022 (C++ workload), CMake 3.20+
git clone https://github.com/Reviusion/ReviANGLE.git
cd ReviANGLE
cmake -B build -A x64         # GD 2.2+ is 64-bit
cmake --build build --config Release

Output goes to build\Release\ — opengl32.dll and gd-angle-editor.exe.

Troubleshooting

Symptom Likely cause / fix
GD won't start, no angle_log.txt Missing ANGLE DLLs — check libEGL.dll, libGLESv2.dll, d3dcompiler_47.dll are next to GeometryDash.exe
GD starts but black screen Backend mismatch — open angle_config.ini, set backend=d3d11
FPS lower with mod than without Set frame_pacing_target ≤ your GPU's worst-case FPS during effects (see config comment)
First-level stutter Enable shader_warmup=true
Online features broken Disable online_block_gameplay (set to false)
AMD/Intel GPU crashes Disable nvapi_profile and gpu_forcer

Что это?

ReviANGLE — это мод производительности для Geometry Dash 2.2, который подменяет opengl32.dll игры на свой proxy. Proxy:

  1. Переводит OpenGL → DirectX 11 через Google ANGLE.
  2. Добавляет 84 низкоуровневых модуля оптимизации:
    • Дедупликация GL state (пропуск 30-50 % redundant вызовов cocos2d-x)
    • Frame pacing на high-res waitable timer (без CPU spin)
    • Снятие мьютекса ANGLE (+6-12 % CPU)
    • Привязка рендер-потока к P-cores (никаких E-core миграций)
    • Резервация VRAM (текстуры не выгружаются)
    • NVAPI driver profile (PSTATE=P0, max-perf, выключение vsync)
    • Отключение Power Throttling Windows
    • И ещё 75+ tweaks — docs/CONFIG_REFERENCE.md
  3. Идёт с отдельным GUI-конфигуратором с двуязычными (EN/RU) описаниями каждой опции.

Зачем?

Ванильный GD написан под OpenGL на железо 15+ летней давности. На слабых системах (ноутбуках с интегрированной графикой или старыми видеокартами) он лагает, упирается в 60 FPS и тратит огромное количество CPU на redundant driver calls. ReviANGLE переписывает этот pipeline.

Быстрая установка

  1. Перейди на Releases и скачай ReviANGLE-vX.Y.Z-win64.zip.
  2. Сделай бэкап папки Geometry Dash (или хотя бы оригинального opengl32.dll, если он есть).
  3. Распакуй ZIP в папку с установленной GD (где лежит GeometryDash.exe). Должно получиться: 
    Geometry Dash/
├── GeometryDash.exe
├── opengl32.dll
├── libEGL.dll
├── libGLESv2.dll
├── d3dcompiler_47.dll
├── angle_config.ini
└── gd-angle-editor.exe       ← опциональный GUI
  4. Запусти GD. Если всё ок — рядом с .exe появится angle_log.txt.

Настройка

Запусти gd-angle-editor.exe для GUI:

  • Двуязычные описания (EN+RU) к каждой опции
  • Enum-дропдауны там где это уместно (backend = d3d11 / d3d9 / vulkan)
  • Комментарии и структура секций сохраняются при save (round-trip safe)
  • Кнопка "Reset to defaults" возвращает best-feel preset для тестового железа

Или редактируй angle_config.ini напрямую — это plain text с полными двуязычными комментариями.

Сборка из исходников

См. docs/BUILDING.md. TL;DR:

# Требования: Visual Studio 2022 (C++ workload), CMake 3.20+
git clone https://github.com/Reviusion/ReviANGLE.git
cd ReviANGLE
cmake -B build -A x64         # GD 2.2+ это 64-битный процесс
cmake --build build --config Release

Сборка попадёт в build\Release\ — opengl32.dll и gd-angle-editor.exe.

Также понадобятся ANGLE prebuilt бинарники (libEGL.dll, libGLESv2.dll, d3dcompiler_47.dll) — см. docs/BUILDING.md.

Лицензия

ANGLE-бинарники лицензированы под BSD 3-Clause и НЕ являются частью исходников этого репо — они кладутся в релизы только для удобства.

Дисклеймер

Это сторонняя модификация. Используй на свой страх и риск. Всегда делай бэкап папки Geometry Dash перед установкой. Автор не аффилирован с RobTop Games.
