Exactly. You need minimum 80GB of space for the download, and then 140GB for the install. But better use 250GB to be safe. After the install the 80GB download folder is deleted, but you need the 250GB workspace to install.
If you later want to patch the game, you need 140GB free space - because Oculus makes a full copy of the game before patching. Thus make sure you have at least 140GB free on the location containing the game if you later need to patch it.
You need at least a GTX 1080 or RTX 2060 to play Asgard's Wrath. Better with RTX 2080. And I'm talking real desktop gpus here, not some weak downscaled laptop gpus. Thus don't bring a knife to a gun fight B)
If you do not have a powerful gaming PC, do not spend time on Asgard's Wrath. 2c.
Btw, I had no problems installing Asgard's Wrath. Right now I'm running the game from my 4TB Samung 860 SSD.
