TSW has always been DX11 by default. DX10 support is likely only there as last-resort compatibility if you have a truly ancient GPU (like a GTX 200- or 300-series which probably couldn't run the game well anyway). If you have a GPU from the last decade then you have been playing in DX11 mode. Users can manually force TSW2 (and presumably TSW3) to run in DX12 mode instead of DX11 but it is not the default.
