Experiencing severe texture flickering in Delta Force on my Colorful CVN B760M FROZEN WIFI D5 V20; do I need to manually tweak RAM timings?

Finally got the system stable; MemTest86 ran 8 consecutive passes with zero errors, and the flickering is completely gone. It was a mess during long-range sniping—distant buildings had these pixel-level jumps that were honestly nauseating. I realized the default XMP profile on the Colorful B760M was way too aggressive for high-load data streams, causing slight checksum errors at 5600MHz. My first instinct was to loosen the tRCD parameters in the BIOS, but that just spiked my overall latency and made the game feel sluggish. I switched gears and used the GamePP BIOS Load-Line Voltage Adjust Wizard to bump the memory voltage from 1.25V to a precise 1.
