After 35 hours of benchmarking, I finally got first place. On my RTX 3060 12GB EVGA XC Edition, I applied liquid metal, new thermal pads and flashed new vbios. I also did a shunt mod, but it was pretty unnecessary. I set up my big 600mm 250W circulation fan and pointed it at my graphics card – the temperatures wouldn't exceed 55 degrees Celsius.
In the end, I ended up with one point more than the guy who was previously first on the leaderboard. I overclocked my card to +200 core and +3600 memory with the ASUS GPU Tweak III tool.
Anyway, the whole leaderboard on Steel Nomad is now full of my scores. It's pretty fun to see.
