DLSS → MetalFX (Automatic)
GPTK 4's nvngx-on-metalfx shim intercepts every DLSS call from Windows games and routes it to Apple's Neural Engine. DLSS Quality, Balanced, Performance, and Frame Generation all work — automatically, with no setup. Cyberpunk 2077, Alan Wake 2, The Witcher 4: if the game supports DLSS, Velocity handles the rest.
Metal 4 Frame Generation
Metal 4's Frame Interpolator generates synthetic frames between rendered frames using the Neural Engine. A game at 60fps displays at 120fps at near-zero GPU cost. Velocity's AI policy engine engages and disengages it automatically based on your hardware tier — no configuration, no flickering, no artifacts.
Neural Engine AI Performance
Every 500ms, Foundation Models analyzes your live frame metrics and recommends whether to engage FrameGen, upscaling, or denoising. The AI runs on-device on the Neural Engine — private, instant, zero network. On Metal 4 hardware it uses structured ML inference. On older chips it uses hardware-tier heuristics.
Protected Game Compatibility
EasyAntiCheat and BattlEye are handled at two levels. GPTK 4 improves Wine-layer compatibility for common check patterns. Velocity's DriverKit virtual HID presents a real Xbox 360 controller to the IORegistry — anti-cheat ring-0 hardware surveys see genuine hardware.
Apple Silicon — All the Way Down
macOS Game Mode routes Wine to P-cores with maximum scheduler priority. E-cores handle background threads. VideoToolbox streams at 2% CPU. ProMotion auto-promotes to 120fps. Unified memory exposes the full RAM pool as VRAM — GPTK 4 no longer artificially caps it at 512MB.
Every Controller, Fully Featured
Xbox, DualSense, Switch Pro, PSVR2 Sense, and MFi controllers all work through Velocity's DriverKit HID layer. DualSense gets full adaptive trigger resistance and HD rumble — the game sends a haptic command, Velocity translates it to CoreHaptics.
AI Crash Intelligence
When a game crashes, Foundation Models generates a plain-English explanation on your device — private, instant, no data leaves your Mac. "The game crashed because EAC couldn't find x3daudio.dll." Not a hex dump. A sentence with a fix.
Hardware HEVC Streaming
Stream to Twitch or Kick at 2% CPU using Apple's dedicated HEVC encoder. M5 Pro/Max uses AV1 for local recordings. 30-second clip buffer runs continuously — ⌘⇧R saves the last 30 seconds without interrupting your stream.
