I have a finished PC title running on a custom OpenGL renderer. Now I want the same experience on Android, iOS, and macOS, with the first playable build targeted for iOS. The visuals cannot drop in quality—the port must keep: • High-resolution textures • Advanced lighting effects • Particle effects Scope of work – Audit the current OpenGL codebase and abstract any Windows-specific calls. – Adapt the renderer for mobile and Apple Silicon, using OpenGL ES 3.x on Android and Metal (or a proven OpenGL-to-Metal layer) on iOS/macOS. – Re-implement input for touch, gyro, and game-controller APIs. – Optimize assets, memory, and shaders to hit a steady 60 FPS on recent iPhones/iPads, then replicate the same on Android and macOS. – Hook in platform services (App Store, Google Play, Game Center, in-app purchases, achievements, cloud saves). – Provide separate, signed release builds plus source patches and clear build instructions. Acceptance 1. iOS build runs first, faithfully matching gameplay and graphics from the PC version. 2. Android and macOS builds follow, sharing the same asset pipeline and feature set. 3. All listed visual features render correctly, with no critical defects. 4. All platforms (Windows, Android, iOS/MacOS) must be developed from a single unified codebase, which will be delivered to the Client upon project completion. Send a short note confirming relevant OpenGL or Metal porting experience and the toolchain you prefer; I will share the full repository and asset pack once we agree on timelines.

Hello, I’m very interested in helping bring your PC title to iOS, Android, and macOS while maintaining the visual fidelity and performance that define the original experience. I specialise in porting high-end graphics applications across platforms, ensuring that advanced lighting, high-resolution textures, and particle effects are preserved without compromise. I understand that the core challenge here is not just porting the game, but doing so in a way that keeps gameplay and visuals identical to the PC version while hitting 60 FPS on modern devices. My workflow would begin with a thorough audit of your current renderer to isolate platform-specific dependencies, followed by carefully implementing OpenGL ES 3.x and Metal layers to replicate the visual effects on mobile and macOS. Input systems and asset optimisation would be addressed alongside shader tuning to sustain performance. I also provide signed builds and clear build instructions for each platform to ensure smooth deployment and future-proofing. In a recent project, I successfully ported a PC-based graphics-intensive simulation to iOS and Android, preserving all lighting and particle effects while achieving a consistent 60 FPS. This approach aligns directly with your current goals and demonstrates that the visual quality and gameplay experience can be maintained across platforms. Looking forward to your thoughts. Warm regards, Henry
