How do I fix random frame drops in Elden Ring on a Sapphire PULSE RX 9070 XT?

I was losing my mind watching my 9070 XT hit 100% load while Elden Ring stuttered badly. I tried lowering textures to High, but RTSS still showed 18-24ms spikes. That just made the game look blurry. I used GamePP to set the GPU clock to 2400 MHz and core voltage to 1.05V via HWiNFO. Now, AIDA64 keeps temps at 64-68C, and RTSS confirms a steady 144 FPS with no dips.
