Why is Crucial DDR5 4800 causing tearing in A Plague Tale?
When thousands of rats swarm the screen, the tearing and stuttering became unbearable, but it was a classic case of bandwidth starvation. Running the Crucial DDR5 4800 in single-channel mode limited me to about 30GB/s, creating a massive 20-40ms delay in data exchange between the VRAM and system RAM. I tried lowering the texture quality, but the game looked like a pixelated mess, which was a total dealbreaker. I ended up reseating the sticks into the proper dual-channel slots and enabling the XMP profile in the BIOS, which pushed the effective bandwidth over 60GB/s. The frame time graph finally smoothed out to a consistent 11-15ms. I had a heart attack when the PC wouldn't boot after the swap—turns out one of the gold contacts was dirty. A quick clean with an eraser fixed it. Now temps are 40-46℃, though they can hit 58-63℃ under peak load. The visual fluidity is night and day.
