Is my Valkyrie V360 pump failing in Metro Exodus?
Whenever I hit those smoke-filled battlefields, the FPS would dive from 80 down to 40, and that kind of stutter makes the combat feel completely sluggish. I noticed the CPU temps were bouncing between 88℃ - 94℃, triggering some aggressive clock throttling. I first tried limiting the max CPU frequency in software, but while it cooled down, I lost about 12 FPS overall—which actually made me excited to try undervolting instead. I went into the BIOS and forced the pump header to a constant 12V output and used compressed air to blow out the radiator dust. Monitoring with RTSS, the frame time stabilized from 18-35ms down to 12-16ms, and the fluidity improved massively. I did have one black screen on boot while messing with the voltage, but a tiny offset tweak to -0.03V stabilized everything. CPU temps now sit at 68℃ - 74℃ with fans at 1400 RPM. Compared the FPS curves, and the performance mode switch is a success.
