Why Radiant Optimizer
Most tweak tools change Windows settings and leave you to figure out how to undo them. Radiant Optimizer takes the opposite approach: before anything is changed, the original Windows setting or game file is backed up, so you can return to exactly where you started with a single click of recovery.
