As for Total War Saga: Troy, we know this game favours Nvidia hardware, and that is clear to see with even the RTX 3080 beating the RX 6900 XT at 1440p. The RTX 3080 Ti is 10% faster than its non-Ti sibling, and just 1% slower than the RTX 3090. At 4K, that gap does widen to 2%, but clearly the RTX 3080 Ti is snapping right at the heels of the BFGPU.
