Upshift 1.0.0

The first public release. Upshift is free, unofficial and open source (MIT License).

• Finds your games from Steam, Epic, GOG, Xbox / Game Pass, EA, Ubisoft, Battle.net, Heroic and itch.io, plus folders you add and an optional drive scan.
• Shows what's inside each game: its DLSS, FSR and XeSS files and versions (with names such as "DLSS 4.5"), DirectX or Vulkan, the engine and anti-cheat, together with PCGamingWiki info and suggestions from the OptiScaler wiki.
• Installs OptiScaler in one click, with a backup of every file it touches and an exact uninstall. Pick the upscaler, frame generation and DLSS model, with a "Which one should I pick?" guide for each.
• Updates the DLSS, FSR and XeSS files a game ships with to newer official ones, in one game or all of them at once. Every new file must be signed by NVIDIA, AMD or Intel, and "Restore original files" brings the originals back.
• Keeps things up to date: new OptiScaler versions (Stable or Beta) keep your settings, with "Undo last update" and repair for changed or missing files.
• DLSS 5 (experimental): switch a game to the DLSS 5 build of OptiScaler and back, with checks for your card and driver.
• Play games through their own store, with launch options, and see a dated list of every change Upshift made to each game.
• Safe by design: games with anti-cheat are never changed, games never start as admin, and admin rights are asked for only when a game folder needs them.
• Installer and portable zip, no admin needed. Upshift updates itself when you choose "Restart to update", and uninstalling keeps your data unless you ask.
