- Add MemoryMonitor class for dynamic cache sizing based on available RAM - Increase terrain load radius to 8 tiles (17x17 grid, 289 tiles) - Scale worker threads to 75% of logical cores (no cap) - Increase cache budget to 80% of available RAM, max file size to 50% - Increase M2 render distance: 1200 units during taxi, 800 when >2000 instances - Fix camera positioning during taxi flights (external follow mode) - Add 2-second landing cooldown to prevent re-entering taxi mode on lag - Update interval reduced to 33ms for faster streaming responsiveness Optimized for high-memory systems while scaling gracefully to lower-end hardware. Cache and render distances now fully utilize available VRAM on minimum spec GPUs.
