What's New in v1.2 (Beta)

• ⚡ Auto-configure for my PC & Restore: Detects your CPU (selecting RPCS3 Alternative Scheduler on Intel hybrid CPUs), GPU tier, motherboard/PCIe link, and system RAM (Mega SPU block size when 7+ GiB RAM is detected, Safe otherwise) to configure optimal settings in one click, with a Restore previous settings button next to it.
• PCIe 3.0 x8 GPU Bottleneck Fix (Issue #36): Automatically detects narrow-link PCIe x8/x4 GPUs (such as RTX 5060 / 4060 / 3050 / RX 7600 / 6600) on PCIe 3.0 motherboards (B450, B350, A320, etc.) and applies Force CPU Blit + Speedboost (disable Write Color Buffers) + Disable MLAA + 100% scale + FSR + Lamp glare 0 to keep races smooth at 60 FPS without green edge artifacts.
• Expanded Handheld & Gamepad Support: Bundles community SDL gamecontrollerdb.txt mappings into RPCS3's input_configs/ folder, adds runtime mapping synthesis as a fallback, prioritizes integrated handheld controls in Automatic mode, and identifies handheld devices (Steam Deck, ROG Ally / Ally X, Legion Go / Go S / Z1E, MSI Claw / Claw A8, Strix Halo, GPD, AYANEO, OneXPlayer).
• Racing Wheel Setup Overhaul:
  • Adds Logitech G923 and multi-device USB support (separate pedals/shifters) with device selection and auto-switching inside the wizard.
  • Waits for calibrated axes/buttons to return to rest before advancing steps.
  • Adds a live Input level progress bar and percentage (0%–100%) during axis calibration.
  • Fixes pedal axis polarity for Thrustmaster wheels (such as T150/T300 where released pedals rest at +32767).
  • Adds a Controls Review & Test screen with live axis meters, button test, and per-axis Invert checkboxes, plus an Invert pedals quick button.
• Graphics & Emulation Improvements: Adds Strict Rendering Mode, ZCULL Accuracy (Approximate, Relaxed, Precise), keeps ZCull queries enabled by default, warns on integrated/low-VRAM GPUs, and blocks mod installation until GT6 finishes unpacking first-boot PDIPFS data.
• Language Switcher & Diagnostics: Adds dynamic English / Simplified Chinese switching, automatic crash-report capture, direct-RPCS3-launch detection, and an updated Log → Save current logs .zip exporter (system-info.txt, launcher.log, RPCS3.log header + tail, and recent crash reports) with an Open folder button.
