OptiScaler is a tool that lets you replace upscalers in games that already support DLSS2+ / FSR2+ / XeSS ( 1 ), now also supports enabling frame generation in those same games (through Nukem’s dlssg-to-fsr3 or OptiFG). It also offers extensive customization options for all users, including those with Nvidia GPUs using DLSS.

• Compatibility list view with detection and OptiScaler install status/version.
• Install from stable, alternate release source, or local OptiScaler archive (.7z).
• GPU vendor settings and OptiFG/Nukem frame generation options.
• Add-ons: Fakenvapi, Nukem FG DLL, nvngx_dlss.dll, ReShade, Special K, ASI plugins.
• Global OptiScaler.ini defaults (merge or replace) during install.
• Default install option presets (hook, GPU, DLSS inputs, frame generation, conflict mode).
• Detect existing OptiScaler installs and offer update/reinstall/uninstall.
• Compatibility refresh diff tracking (+added/-removed/~changed) with row highlighting.
• Per-game workaround template auto-apply on detected game selection.
• Version-aware add-on behavior for newer OptiScaler builds (0.9+ bundled component handling).
• Post-install verification report with INI and file checks.
• Archive provenance metadata (source URL, size, SHA-256 fingerprint) in install manifest/log.
• Built-in installer update checker with optional startup auto-check and non-intrusive in-app notice.
• About window with current/latest installer version, release date, installer repo link, OptiScaler repo link, and author.
• Diagnostics export bundle (logs, settings, detection snapshot).
• Configurable URLs for lists and releases.
• Anti-cheat signature hints in detection results with install-time warning prompts.
• Optional custom folder scan source and startup compatibility auto-refresh toggle.
• FSR4 INT8 (Experimental) workflow with detected-game picker and optional visibility override on unsupported GPUs.
• Robust GPU detection using adapter vendor IDs (with fallbacks), and detected GPU model shown on the title bar.

• Windows 10/11
• .NET 10 SDK (for building)
• Visual Studio 2022/2026 with WinForms workload (optional)

[Major]

• Added Experimental FSR4 INT8 installation (This tab by default is only visible if you own an AMD RDNA card)
• Hardened GPU detection using adapter metadata and PCI vendor IDs (VEN_10DE, VEN_1002, VEN_8086) with safe fallbacks.

[Minor]

• Added detected GPU model to the main window title bar.
• Hardened OptiScaler detection to reduce false positives.
• Improved game executable resolution for nested binary layouts.
• Added startup setting to enable or disable automatic installer update checks.
