Update 1.3 (often referred to colloquially as version 1037 in back-end distribution logs) was supposed to be the "stability savior." Released in late spring, it introduced:
But for a subset of users—specifically those running high-end NVIDIA 40-series cards and Windows 11 24H2—the patch created as many problems as it solved. Crashes referencing memory address errors became known colloquially as the "1037 runtime trap."
Enter the 1580exe exclusive.
If you look in your Windows Task Manager while running Horizon Forbidden West post-1037, you will notice not one, but two executables: the standard HorizonForbiddenWest.exe and a secondary process: 1580exe .
Guerilla Games has a history of playing the long game. Remember the secret "Master Chief" radar blip in HZD? Or the mysterious door in FW that took six months to open?
Update 1.037 is a sleeper agent. It isn't meant to fix your game; it is meant to prime your console for a reveal.

Until Guerilla speaks up, we are left in the dark. But one thing is certain: Do not delete Update 1.037. Whatever is lurking inside that 1580exe branch is the key to the next chapter of the Horizon saga.
Stay dangerous, hunters. And watch the skies. The machines are learning.
