Is the rendering pipeline causing lag on RX 9070 XT in Space Marine 2?
When hundreds of Tyranids flood the screen, my FPS would plummet from 120 down to 45, which was honestly anxiety-inducing. The core clock on my VASTARMOR Radeon RX 9070 XT Super Alloy PRO was jumping by 200-400MHz at peak load, clogging the rendering pipeline. In a panic, I tried an aggressive PBO profile in the BIOS, but the system just blue-screened the moment combat started. That's when I realized the voltage was the real culprit. I locked the core voltage at 1.1V and disabled Radeon Anti-Lag in the driver, switching to the game's internal sync instead. RTSS showed my 1% lows jump from 42 FPS to 78 FPS—a massive leap in fluidity. I also tried lowering the resolution first, but the jaggies were hideous until I enabled FSR Quality mode and tweaked the sharpening. Now, GPU temps sit at 68-75℃ with fans at 1800-2100 RPM. 3DMark stress tests confirm the load is balanced and the input lag is gone.
