How to stop clock speed fluctuations in Stalker 2 with B240?
While stalking targets, I noticed the FPS was jumping in a weird pattern, diving from 100 to 60 suddenly, which made precision shooting a total gamble. The B240 cooler was doing its job, but the default Windows power management was way too aggressive, causing the CPU to swing between 1.5GHz and 4.8GHz during load shifts, leading to frame time spikes of 20-35ms. I tried Game Mode, but it only tweaked the peaks without fixing the lows—just another surface-level fix. I went into the BIOS, disabled C-State energy saving, and forced the minimum processor state to 100% in the power plan. Now, clock fluctuations are within 0.1GHz and frame times are steady at 8-12ms. Disabling C-States did bump my idle power by about 15W and raised temps by 3℃, but the absolute stability is worth it. CPU temps are now 62-68℃ with fans at 1300 RPM. After three hours of testing, the drops are gone, and the fans are stable at 1300 RPM.
