Can I fix Metro Exodus tearing by adjusting G.Skill DDR5 timings?

Running this 6400MHz kit felt like a gamble. The bandwidth is insane, but the default timings were sluggish. While sprinting through the wasteland, the tearing was brutal, and RTSS showed frame times bouncing wildly between 11ms and 28ms. I tried turning on V-Sync, but the input lag jumped to 60ms—it felt like I was wading through mud, which is just pathetic. I decided to go aggressive with the secondary timings in BIOS, crushing tRFC from 480 down to 320 and pushing tREFI up to 65535. In latency tests, I saw a drop from 72ns to 61-64ns, and the tearing visually vanished by about 80%. I actually blue-screened three times while tightening the timings until I bumped the voltage from 1.4V to 1.45V. The RAM is running hot now, between 52-58℃, and the heatspreaders are practically scorching. I exported the data via a frame time analyzer, and the generation time is now a consistent 5.1-6.4ms.
