Changelog 1.8.7

🚀 New Features

• OptiScaler Enhancements:
  • Added Preferred Upscaler option support to select a preferred upscaler profile.
  • Added Force FSR4-i8 option to force the INT8 model on unsupported GPUs (available under the Bleeding-edge channel).
  • Implemented dynamic layout adjustments under the Bleeding-edge channel: hides the redundant FSR version dropdown (locking it to "Latest") and aligns the "Force FSR4-i8" checkbox in its place.
  • Preserved the Emulate FP8 checkbox on the Bleeding-edge channel, updating its tooltip dynamically to explain its role in activating FSR MLFG on RDNA3 GPUs.
  • Enabled automatic synchronization of OptiScaler.ini and fakenvapi.ini on game launch.
• Low Latency & pascube benchmark information:
  • Integrated vulkan-low-latency-layer dependency status and UI management on the Home tab (renamed to Korthos low latency).
  • Added CPU/GPU max power and temperature along with version tracking for PasCube.
• System Integration:
  • Added a "Create Steam shortcut" option in the settings menu, making it easy to launch GOverlay inside Steam's Gaming Mode (useful for handhelds like Steam Deck).
  • Added persistent Intel CPU power monitoring fixes, triggering proactively and restricting execution strictly to Intel hardware to avoid side-effects.
  • Implemented detection for non-Steam AppImage games and improved cover art port mapping.

🔧 Fixes & Stability

• Appimage:
  • Several problems in the old appimage builds are now fixed.

• Compatibility & Platform:
  • Fixed Flatpak configuration paths to properly respect XDG_CONFIG_HOME.
  • Whitelisted safe ASCII characters during game name sanitization to prevent naming conflicts.
  • Ignored crash and bug report folders in Unreal Engine directories during game path discovery.

🎨 UI & Polish
