GTX 760 is the minimum GPU listed on steam, which is a 1.8TF-2.2TF card.
It also needs 8gb of ram + 2gb vram card.
Basically listed Minimum requirements are WAY above the Switch, and marginally above the PS4/XBO on ram/gpu and substantially above ps4/xbo on cpu.
Getting the game to run on the Switch Docked, but especially in Handheld, would be an absolute nightmare.
I see Tegra X1 given with 1TF, which is not way below 1.8TF.
That is the FP16 figure (half precision) thus double the number. It's single precision (FP32) is 0.5TF.
But the Switch is also downclocked a little it runs at 0.4TF docked and 0.2TF undocked, or 384Gflops & 192 Gflops to be more precise.
