just weeks away from launch, Blackbird Interactive has done what surprisingly few developers do these days: updated and released a comprehensivechart. For gamers using a modest PC, it looks very promising, but if you're hoping to play it at 4K with maximum graphics, you're going to need the very best gaming hardware.
Those are both six-core processors, though AMD's does offer multithreading support for 12 threads in total. That Intel chip dates back to 2018 so it doesn't look like Homeworld 3 will be especially CPU-heavy. That said, it is a real-time strategy game set in space, so I should imagine that in really big battles, especially online ones, the 9600K might struggle a bit., which is a seven-year-old GPU.
Going to the other scale of things, 4K gaming on the Epic preset needs far more recent and potent hardware. A Core i7 12700K or Ryzen 7 7700X for the CPU, and anfor the graphics card. So you're looking at processors with eight or more cores and while that makes more sense for this type of game, it's rare to see any game actually use that many threads.Those GPUs aren't the latest models, of course, but neither are they lightweight offerings.
If I have one criticism of Blackbird Interactive's system requirements is that while they're pretty comprehensive, the chart says nothing at all about expected performance—in other words, what kind of frame rate should expect to see with that hardware and setting combination.
