It’d be interesting to hear if anyone with some UE4 experience has thoughts on the min-spec machine (CPU/GFX/memory mainly) it may be possible to aim for with a PC FPS game. Potential min-spec for a game with simple graphics / gameplay (UT2003?) to an FPS with graphics and gameplay features comparable to those shooters from the past year(s).
Aiming for high-end all-bells-and-whistles is tempting with all the graphical features in UE4, but it can severely limit the potential audience. Something very important to consider for many smaller devs.
I understand UE4 is still in heavy development and will be for a long time - no games have yet shipped with it. There are probably a lot of optimizations still to go in as AAA developers optimize in the months before shipping and we (hopefully) get some of these optimizations in the github repo (perhaps some optimizations from fortnight is planned to be merged in as well?).
