lowering foliage draw distance, LODs, Volumetrics, particles, crowd density etc. does lower your draw calls though.
Yeah, the series X has a faster GPU that can take advantage of the slightly higher clocks for higher framerates or additional detail/objects.
Practically speaking that 6% makes no difference whatsoever in terms of whether or not you can do something. Maybe the series S drops a few frames below it’s target when something intense happens, that’s going to be about it.
The memory bandwidth is shockingly halved with 2GB of it running at 1/10 the bandwidth of the X though, I see that being a huge issue in many titles.
