With the GPU requirement listed being a NVIDIA GeForce GTX 650 Ti or better, the CPU a Intel Core i5-4460, and only 4GB of RAM - the only part of Shenmue 3's PC requirements that reminds us that we're in 2018 is the 100 GB of available storage space needed. For some reason. Of course as the game is still in development this could all change, but the specs were posted as part of the latest Kickstater update
The backer update itself was more survey related so the specs were posted for those interested in the PC version. The modest hardware requirements point to the early screens we've seen so far being indicative of the final game - in that technically clean and decent looking, not exactly on the cutting edge of visuals.
On the plus side, the presentation should scale incredibly well and we should expect 4K output across both the PlayStation 4 Pro and most modern day gaming rigs.
