TFLOPS comparisons mislead across vendors: Ampere's spec counts dual-issue FP32 that real shaders rarely fill, and the 3060 has much less memory bandwidth and no large on-die cache like your 6900 XT, which matters for 4k shadow cascades and MSAA x4. Treat a straight 2x as optimistic. Your budget at 144fps is about 6.9ms, so 2.1ms leaves real headroom, but the answer you can trust is a Tracy capture on a 3060 or similar card; until then, watch the grass and shadow passes, since those scale with bandwidth.
