Can disabling C-State fix the lag on Biostar H310MHD3 in Helldivers 2?
Every time a massive explosion went off, my frame rate would take a dive. It's incredibly distracting when you're trying to time your dives. The power delivery on this Biostar H310MHD3 had a response lag of 25-35ms, causing the CPU to swing wildly between 3.1 and 3.6 GHz. I tried 'Ultimate Performance' mode in Windows, but the CPU hit 88℃ almost instantly, which felt way too risky. I went into BIOS, completely disabled C-State power saving, and locked the minimum CPU voltage at 0.95V. In RivaTuner, the frame time variance shrank from 12-38ms down to a smooth 11-15ms. I did notice the PC pulling 15W more at idle, but adjusting the low-load fan speed balanced it out. CPU temps are now 72-78℃ and VRMs are at 65-71℃. The frequency curve is finally flat, but the idle power draw is a bit annoying.
