Games, not a PC optimizer download
Radiant Optimizer is also the name of a Windows optimization product. The projects here are separate browser destinations. This is an independent directory, not its official website.
These entries were checked on desktop Chrome on October 10, 2026. An accessible page is not proof that a full game works, is free, or is approved by its publisher. WebXash requires your own files; Diablo's full-game mode also needs your own data.

Common questions
Is this the complete Radiant Optimizer games list?
No. This collection covers 5 projects traced to the shared list. Other entries have not been verified for inclusion here. Follow the original game-link reply for the full source. The homepage also contains editorial picks that are not attributed to Radiant.
Do I need to install Radiant Optimizer?
The links lead to separate browser projects. Our checks did not establish any need to install the Windows optimization product. Follow each game project's current requirements.
Can I play these games on a phone?
Mobile gameplay has not been tested. Surfd specifies desktop keyboard and mouse; do not treat these entries as verified mobile games.
Does Skate 3 run without game files?
The linked fan project says it streams data from your own converted copy. We did not supply files or test gameplay. This site does not provide game data.
Is this the official Radiant Optimizer website?
No. Tab Game Guide is an independent directory and is not affiliated with Radiant Optimizer, project authors, or game publishers.
