I'm getting terrible input lag in Crimson Desert during city expansion on my ASUS TUF B760M-PLUS D4. Should I disable power saving?

Dealing with a few milliseconds of lag in an open world is a nightmare. I started by stripping all background apps to the absolute minimum. My latency tester showed memory response times swinging randomly between 65ns and 80ns, which is lethal when you're trying to turn quickly in combat. I tried the 'High Performance' power plan in Windows, but it only shaved off 2ns and the spikes remained. That's when I realized the motherboard's memory power-saving features were the problem. I went into the BIOS, disabled every single memory power-saving option, and enabled High Performance mode. The latency finally stabilized at 58-62ns. I did have some minor stuttering at first, but locking the memory voltage at 1.35V fixed it. Chipset temps are sitting at 42°C - 47°C, and the overall feel is a massive leap forward—the controls finally feel precise. Verified with a timestamp analyzer, the response time is now a rock-solid 58-62ns.
