Elgato practically has the monopoly on video game capture at this point. There are dozens of solutions from other companies, but Elgato has been at the forefront for so long that its offerings have simply pulled ahead. The Elgato 4K S takes all of that to the next level.
Anyone who watches my very occasional Xbox game streams on YouTube and with the Xbox Two Podcast will know that I have occasionally seen issues with game capture. Whether it's HDMI sources not registering or capture feeds getting corrupted, my weird and extreme setup has often caused strange issues as I've tried to use Elgato products beyond their intended parameters.
