YOUR HARDWARE, IN VIEW Interface preview · Example data ↗
01 / WINDOWS TUNING
Make Windows work for your next session.
Review performance, input and background settings without hunting through menus. Read the trade-offs, then choose what fits.
Availability depends on Windows, your hardware and the setting. Custom tuning is something to compare on your PC.
02 / GAME & APP PROFILES
A setup for the games you actually play.
Find supported profiles for your games and everyday apps. Review the settings before making a change.
Supported settings vary by game, app version and detected installation. Save work before closing apps.
03 / NETWORK & LATENCY
See what’s behind the lag.
A fast download isn’t the whole story. Check your connection, look at delay under load and explore supported Windows network settings.
Network tweaks include supported receive processing and Windows download controls. Server hit registration and your internet route remain outside Radiant’s control.
04 / DIAGNOSTICS & MONITORING
Find out what your PC is doing.
Follow real readings, compare your runs and investigate the parts of your setup that need attention.
Results describe the workload you run. A clean sample is not a hardware health guarantee; sensors and game capture support vary.
05 / TOOLS & RECOVERY
You choose what changes.
Start with a scan. Test your inputs. Review recovery options before you make changes to your setup.
Some actions need administrator access. Review the effects and keep backups of important files.
