Upon further googling the consensus seems to be that the Series S's GPU is equivalent to a GTX 1650, which actually benches worse than the RTX 2050 Laptop. I think there's no question that a power starved 2050, running in handheld mode, will run slower than the Series S GPU, however if docked it can run at a full 30W then maybe it's not crazy to believe that a Switch 2 could be in the same ballpark as Series S...
Incidentally, DF also describes Alan Wake 2 on Series S, as 'perfectly fine'. It runs at approximately the same settings as the Series X performance mode, but at 30fps and with a slightly lower internal resolution. So unless I'm off with some of the above, a docked S2 may well be able to deliver a perfectly acceptable experience. In handheld, if the internal res is reduced to 540p or lower, who knows...
All this supposes that S2's GPU is built on the same 8nm process as the 2050. If however it's moved to a more modern node then that will only work in S2's favour.
