What is this Radiant Optimizer site?
An independent community directory inspired by the browser-game list shared by @RadiantOpti. It brings game links and practical gaming calculators together. It is not the official Radiant Optimizer Windows app.
Can I play every game inside this site?
Many games open in our embedded player. Some hosts block embedding, need their own tab, or are temporarily unavailable. Every game has a link to its original host. Some ports require your own game files.
Do these tools change my PC settings?
No. These calculators run in your browser and help you compare settings. They do not install software, change Windows settings, or promise an FPS boost.
Where are my saved games stored?
Bookmarks stay in this browser on this device. There is no account to create. Clearing site data will remove them. If browser storage is blocked, favorites last for the current session.
