Quantitative Performance Bottleneck Analysis in BioShock 4
Linear benchmarks are lying to you; they mask the actual compute distribution in BioShock 4's messiest scenes. My early attempts to tweak single-thread priority were useless and only triggered the power wall early, leading to forced throttling. I had to go the hard way with stepped stress testing, ramping up from 50% in 10% increments to find the exact breaking point. Using a ZOTAC GeForce RTX 2060 SUPER-8GD6 Supreme PLUS OC, I cross-referenced a 3DMark stress report which revealed that multi-core usage spikes between 85% - 92% coincide with sharp clock drops. It's an annoying ceiling that feels like a driver limitation. I managed to push past some of this by overriding the thermal limits, but I've found that in extreme explosion-heavy sequences, the FPS still dips. It’s a stark reminder that you can't just software-magic your way out of hardware age. The stability is better now, but it's not an overnight miracle for an older card.
