What causes random stutter in Elden Ring and how do I fix it on a Sapphire 9070 XT?

The stuttering in Liurnia was making me question my entire build. I updated my BIOS, but GPU-Z still showed clock speed fluctuating between 1500-2000 MHz. That didn't solve the issue. I used GamePP to lock the frame rate to 144 FPS and disabled background processes. After this, HWiNFO showed consistent 65C temps, and RTSS confirmed frame times stayed between 6-8ms, completely eliminating the micro-stutters I was experiencing.
