Radiant Optimizer — What It Actually Is
Two things circulate under this name: a Windows PC optimization tool for gaming, and a community "game list" of browser-playable fan builds. Here's what each one is — and what the searches usually mean.
The Windows optimizer
What it does
Tunes Windows and supported game settings in one place — game profiles, power settings, CPU controls and NVIDIA options, plus diagnostics.
Undo is built in
Supported changes include backup or undo — configs are read and written on disk, never memory, and backed up before every change.
Free vs Premium
Free to start with no card — Game Profiles (per-game graphics presets and frame caps) sit on the Premium side.
Honest limits
It tunes your PC's settings — it can't fix a game server's hit registration or make a weak GPU strong.
Supported games
The Game Profiles screen lists 20 titles — cards show detected status and open graphics presets or config review.
| Category | Games |
|---|---|
| Shooters | Apex Legends, Battlefield 2042, Black Ops 7, Modern Warfare III, Warzone, CS2, Fortnite, Marvel Rivals, Overwatch 2, PUBG, Rainbow Six Siege, The Finals, Valorant |
| Moba / strategy | Dota 2, League of Legends |
| Open world / other | Cyberpunk 2077, GTA V, Minecraft (Java), Roblox, Rocket League |
The "game list" people search for
A different thing entirely
Fan directories circulating under the same name list browser-playable community builds — Black Ops zombies, Halo CE, Quake, DOOM and retro classics rebuilt for the web.
Fan recreations, not originals
Entries are community projects — ports, remakes and shareware-era titles running in a browser tab, not the retail games.
Mixed reliability
Listings carry status labels like "experimental" or "not linked" — a listed address proves an entry exists, not that it still runs.
Two separate projects
The Windows utility and the browser game directory are different projects — searching one often lands you on the other.
FAQ
Is Radiant Optimizer free?
Free to start with no card — the per-game profile tools are Premium.
Is it safe?
Its own docs say configs are disk-only with backups before every change — still, create a restore point before any optimizer touches system settings.
Does it work for my game?
Profiles exist for 20 titles — Fortnite, Valorant, CS2, Roblox, Warzone and others in the list above. Unsupported games only get generic Windows tweaks.
What's the browser game list?
A separate community directory of fan-built browser versions of classic shooters and retro games — unrelated to the optimizer's tuning features.
