Borderlands 3 became available on Google Stadia on 17 December 2019 along with Dragon Ball Xenoverse 2 but the looter shooter version that came to Stadia was available to PC and console players back October of the same year.
Gearbox Software's fiesta is running at full speed on PC and consoles as these versions of Borderlands 3 received numerous updates as we are heading into 2020. Meanwhile, Stadia's version of the game will kick off at a snail's pace as it released on 17 December 2019 but the game build is based on the version from 24 October 2019.
This means it will launch without any updates that were released between the two dates which is roughly almost two months worth of patches. However, Gearbox did state some of the features should be arriving shortly and the Stadia version is expected to catch up with the rest in early 2020.
Stadia catching up to other platforms is tied to the release of the first expansion, Moxxi's Heist of Handsome Jackpot which will bring more contents for the Vault Hunters.
While lagging behind the other platforms could be written off as Stadia just entering the scene just recently, the troubles don't stop there. There are reports of the platform which was advertised, sort of.
Namely. Google mentioned the game would run in "up to 4K 60 FPS" but it appears the players didn't see the actual implications of the statement. Many assumed this was only a matter of their own bandwidth but now it looks like Stadia's servers may not be able to handle it either.
It also remains to be seen whether this is a matter of Gearbox Software's optimisation. This would be the best-case scenario for Stadia users as a future patch that increases performance would be much more likely than Google swapping out their server hardware in order to run 4K Borderlands 3 smoothly.
