How to calibrate real-time monitoring for Lost Ark?
I took a deep dive into the rendering pipeline to figure out these frame time swings. I noticed that whenever the core clock fluctuated between 4.8GHz - 5.2GHz, the frame time jumped wildly from 13ms - 19ms, causing some pretty nasty screen tearing. Here is the toolchain I used: I cranked up the sampling frequency in MSI Afterburner, used HWiNFO to catch the frame time deviations, and then set a hard cap using a frame limiter. The dynamic amplitude showed that after calibration, the frame time variance shrunk from a 6ms swing to under 1.2ms. The tearing is basically gone now, and the fluidity during chaotic raids is a massive upgrade, with input lag sitting steady at 12ms - 18ms. The calibration check confirms the sampling rate is actually sticking. Breaking down the render link to sync the sampling rate is the only way to stop the monitoring data from lying to you.
