Radiant Optimizer download: official site and safety checks
We do not host or mirror the installer. This page points to the vendor's site and lists what to check before you run anything.
Official site: radiantoptimizer.com. The free edition needs no payment details and Premium is $57.77 USD, paid once, per the vendor (read October 10, 2026). Windows 10 and 11 only.
How to tell you are on the right site
- The address bar shows radiantoptimizer.com exactly, over HTTPS.
- The link matches the one on the vendor's own social profile.
- This site, radiantoptimizer.website, is an independent guide, not the vendor, and hosts no installers.
- Other domains that use the name, including guide sites, are not the vendor. Do not download from them.
Before you install
- Create a Windows restore point and back up important files.
- Scan the downloaded installer with an online multi-engine scanner. A clean scan lowers risk; it is not proof of safety.
- Read the license terms and the refund policy.
- If a tool asks you to disable security protection to install, stop and investigate before continuing.
- Do not install on a work or school PC without administrator approval.
After you install
- Change one setting at a time and keep a note of what you changed.
- Measure the same game scene before and after.
- Check the game's anti-cheat policy before playing online with any tuning tool.
