Why is Civ 7 lagging during late-game turn processing?
When hitting the late-game on massive maps, the turn transition wait times suddenly spiked, making the strategic flow feel sluggish as hell. The default XMP profile on my Asgard Bragi II DDR5 6000 was struggling with the heavy AI compute load, causing memory latency to jump wildly between 72-88ns. I first tried enabling 'Ultimate Performance' in Windows, but it did absolutely nothing for the calculation time—a shallow fix that didn't touch the hardware bottleneck, which was beyond frustrating. I eventually dove into the BIOS Advanced Memory settings, manually bumped the voltage from 1.35V to 1.38V, and locked tRCD at 36-36-36. Running AIDA64, I saw the read latency tighten up to 64-67ns, and those instant hitches during turn processing basically vanished. I did hit a snag where the system failed to boot twice after the first voltage lock, but it finally stabilized once I loosened tRFC to 480 cycles. Temps sat between 45-52℃ with fans humming at 1300-1500 RPM. HWiNFO confirmed the memory controller load curve flattened out, and frame generation time finally locked in at 5.1-6.4ms.
