Halo Reach has been released on Steam but the system requirements there don't include the updated minimum which was provided by 343 Industries on release. Apparently, we can run the game with integrated graphics, at 30 frames per second.
Halo Reach's system requirements weren't high to begin with, since they allowed 4K 60 FPS gaming with a six-year-old GPU that wasn't even top of the line back in its day. GTX 770 was still a pricey and really good GPU for its time but since this is 2019, 4K gaming on it is still an impressive feat.
However, that is not the only interesting quirk 343 have in store for us. On 3 December 2019, when the game was released, the developers revealed the updated system requirements, as the ones from late October 2019 didn't include minimum PC specs for gaming under 60 FPS on average.
The new specs have exactly that - 30 FPS requirements. According to these, Intel UHD Graphics 630 or Radeon Vega 10 Mobile are enough on the GPU end while the CPU requirement would be Intel i7-8750H or AMD Ryzen 7 2700U.
While the Intel CPU requirement is somewhat beefier, it is running with the integrated graphics. Furthermore, the RAM requirement remains 8GB even here, which is not entirely surprising since the remaster did have the current console generation in mind.
According to 343 , these components will be enough to run Halo Reach in 30 FPS on average, which could potentially bring fans back into the golden age via nostalgic time travel. Or they could just go with some rig that's more capable than that and play the game in 60 FPS.
Considering that Reach is getting negative reviews primarily for the input lag, it wouldn't hurt to give yourself a little bit of an edge with an increased frame rate.
