GTA VI on Intel Core i5 14600KF keeps hitting frequency bottlenecks that tank frames, does Intel XTU optimization with config backup actually boost performance?

In heavy load scenes of GTA VI the Intel Core i5 14600KF frequency bottlenecks send frames straight down and I ran stress tests feeling nervous about stability. Intel XTU optimization first adjusted voltage but the system fluctuated at first then fine tuning parameters finally let everything run normally. The crash risk lingers especially when pushing high frequencies so even after tweaking there remains some limitation and this processor really needs strong cooling and stability. Later I backed up the config and temp curve stayed reasonable while performance smoothed out nicely though in long high load sessions you should still monitor voltage to stop surprise restarts ruining the flow.
