Fixing performance dips on Zotac RTX 2060 Super
During heavy shadow rendering, my FPS would plummet from 55 to 20, which is just pathetic scheduling. The Zotac GeForce RTX 2060 SUPER was hitting a 175W peak, triggering the hardware power wall and tanking the core clock from 1800MHz down to 1200MHz. I first tried cranking the power limit in MSI Afterburner, but the card shot up to 88°C and the fans sounded like a helicopter taking off. That was a suicide mission. Instead, I tried the opposite: I manually dropped the power limit to 90% and paired it with an aggressive custom fan curve, forcing 85% speed between 65-80°C. HWiNFO showed the clock fluctuations stabilize from 1200-1800MHz to a consistent 1500-1600MHz. While peak performance dropped slightly, the minimum FPS improved massively. I actually messed up the voltage offset at one point, which caused the game to crash the moment a fight started, until I reset it to default. VRAM temps are at 78-84°C and core temps are 68-74°C. I saved the profile using a config export tool. Backup successful, and fan speeds are steady at 1400-1600 RPM.
