Why is my Sapphire Pulse RX 9070 XT choking in Far Cry 6?
While trekking through the thick vegetation of Yara, my frame rate was swinging wildly between 85 FPS and 42 FPS, making combat an absolute nightmare. I initially thought it was a driver conflict and tried rolling back three versions, but that actually made the stuttering worse—a total waste of time. After digging into the VRAM usage, I noticed that while the 16GB on the Sapphire Pulse RX 9070 XT is plenty, the memory management was hitting a scheduling latency of 14-22ms during high-density texture loads. I went into the driver panel, set the Shader Cache to 'Unlimited,' and forced 'High Performance' mode. Monitoring with HWiNFO showed the frame times tightening from a messy 11-25ms range down to a rock steady 8-12ms. Interestingly, the first time I tweaked the cache, game boot times jumped by about 30 seconds until I rebooted and cleared the temp files. GPU core temps stayed around 66-71℃, while VRAM hovered between 82-88℃. I used a system config tool to export these scheduling parameters, and now the frame time is locked at 8-12ms. It's a relief to finally stop the stuttering.
