## Questions and answers

### What is Radiant Optimizer game?

The phrase can lead to Radiant’s Windows software and to browser games shared by its account. Choose the collection that matches what you want to do.

### Do the browser games need the optimizer?

They run on separate project sites. Their own requirements determine access; this directory does not require an optimizer purchase.

### Are all the games ready to play without files?

No. Some projects need your own game data or provide a limited demo. The cards identify those setup paths.

### Have you tested an FPS improvement?

No. PC guides explain sources and a comparison workflow. They do not publish measured FPS gains.
