Doom Eternals next-gen upgrades are out today for PS5 and Xbox Series X/S, bringing de rigueur enhancements to last years well-received first-person shooter. The upgrade is free, but it also more or less tells PlayStation players to go to hell. To wit: Theres no way to carry your campaign save data from the PS4 version to the PS5 one.And, oh yeah, that PS5 version is currently busted for some players.Following the Tuesday morning rollout of Doom Eternals next-gen upgrades, some players (myself included) found themselves locked out of the PS5 version. In my case, I downloaded the requisite upgrade file, but the PlayStation Store still listed Doom Eternals snazzy PS5 version at full price. On the PS5 dashboard, a little lock sign popped up next to the games launch icon. To play, Id have to switch over to the PS4 version. Other playersshared similar issues. Bethesda, Eternals publisher, acknowledged the issue in a tweet on Tuesday, and said its currently working with Sony on a fix.Doom Eternals PS5 version will eventually get fixed, but itll still be lesser than other PS4-to-PS5 upgrades. The total lack of a save-data transfer poses a stark contrast to how cross-gen upgrades have functioned so far on the console. For instance, with the PS5 version of Marvels Avengers, you can copy your hard-grinded progress between generations. You simply have to download the PS4 version, hop into the main menu, upload your save data to the cloud, download the PS5 version, go into that main menu, and then re-download your save data. Final Fantasy VII Remake Intergrade, the currently PS5-exclusive version of Final Fantasy VII Remake, requires a similar set of steps. Yes, the process is often a pain, but at least you can do it.And then theres another contrast: Upgrading your games from Xbox One to Xbox Series X/S is generally pretty smooth. With Doom Eternal, that remains the case.How To Upgrade Doom Eternal On Xbox Series X Or SIf you own Doom Eternal on Xbox One, your Xbox Series X or S will automatically upgrade it to the next-gen version. Youll be able to pick up where you left off in the campaign, provided youve connected your console to the internet. This is all thanks to a background feature called Smart Delivery. (How it works: Basically, if a game exists across console generations and is part of Smart Delivery, you get the next-gen version without any effort or financial commitment on your part.)Read More:Xbox Smart Delivery Turned Out To Be A Pretty Big DealHow To Upgrade Doom Eternal On PS5Upgrading Doom Eternal on PS5 requires several steps:Open the PlayStation Store on your console.Search for Doom Eternal Campaign - PS5 Upgrade.

Those fine with 1800p resolution can activate modes that offer either ray-tracing or 120fps frame rates. (Ray-tracing isnt available on Xbox Series S.)

Its just that one is a little bit of a pain.As we pass the six-month mark of this console generation, its clear the story around their differences is less to do with performance and more to do with features. Doom Eternals next-gen upgrades are just the latest footnote. One system demands you to jump through hoops for a download and then prevents you from accessing your old save data earned over the course of a 25-hour campaign. The other does not. At that point, how much do teraflops and storage space and imperceptible performance benchmarks really matter?
