How to fix texture flickering on Vastarmor RX 9070 XT in Deathloop?
During those tense moments when an enemy is about to strike, I noticed some bizarre pixel flickering on the edges of the screen. It was a really unsettling visual glitch. The Vastarmor RX 9070 XT tends to downclock way too hard during low-load scenes, which causes a tiny sync delay in the memory controller when it tries to ramp back up. I first tried 'Max Performance' in the driver settings, but while the flickering stopped, my idle power draw shot up from 15W to 40W, which felt like a waste of electricity. I ended up using a clock control tool to lock the core frequency between 2400-2600MHz and tweaked the memory voltage. The rendering latency dropped from a random 15-40ms mess to a smooth 11-14ms. I actually crashed the game a few times at first because I set the voltage too low, but 1.1V seems to be the sweet spot. Temps are 52-60℃ with fans at 1300 RPM. 3DMark confirms the flickering is gone, though locking clocks is a bit of a chore.
