Radiant brings Windows performance and gaming-related adjustments into one application. The useful question is which changes you need—and whether they help your own setup.
Start with the free tier
The vendor says the free version can apply some optimizations without an account or payment card. Check its scope before paying for the full license.
Understand the license
The official site lists the full version at $57 as a one-time purchase, with future updates included. It links the license to the motherboard; transfers may require support.
Keep claims and results separate
The vendor describes restore points and an undo function. We have not tested recovery behavior, anti-cheat compatibility or FPS improvements. The site's performance illustration is not an independent benchmark.
Where should I download Radiant?
Use the download entry on radiantoptimizer.com. FrameLedger does not host an installer or a mirror. Review the vendor's current system requirements and instructions before installing.
What should I check before buying?
Confirm the current price, free-tier limits, hardware-binding rules and refund policy. The vendor currently describes completed purchases as final. Test the free version first.
Is it safe, and will it increase my FPS?
We have not run the application or independently verified its safety and performance claims. A feature list or vendor promise cannot establish the outcome for a particular computer. Keep a baseline and use a repeatable test before drawing a conclusion.
