I know this isn't Redfall specific, but I feel like MS should designate a specific team to go round and improve a bunch of existing releases on XSX/XSS.
Perhaps say the team that did the FPS boost work? and the Back compat work - assuming it's the same team.
Give them some time, and tell them, anything MS owned needs to be "Best on XSX" - EG. Ghostwire, Deathloop,
Also try and get to EA, and offer to do the same for them. Eg. Jedi Survivor and Dead space remake.
Then get this team to help fix the perf problems in Redfall!
The most powerful console narrative only works, if you can back it up with the perf numbers in big releases.
It does look like UE5 titles will end up performing slightly better on XSX vs PS5 ( based on fornite )
The collation and undead labs both have small teams to help with unreal 5 development apparently. I am sure also that ID would be able to help with ID tech stuff and likely already do at Bethesda. I think the forza engine is fine and its only used by the forza teams.
I think the problem is that there are way to many engines that they are using. The halo engine (slipspace ?) Forza tech , Id Tech, Unreal 4 , Unreal 5 now , Gamebryo/creation are just the ones I know of off the top of my head. It sounds like internally they are looking to Ditch the halo engine for the next game and go to either id tech or uneal 5. So at least there they are dropping one engine.
This was the first unreal game that Arkane made the previous ones I think where crytek so that may be where some problems come from. Also this game was originally going to be on last gen and ps5 until the purchase. So much of its development life would have had the development spread across all that. Likely it didn't help its cause.
Like I said, lets hope this is the misstep from the bethesda purchase and MS goes and looks at everything in the pipeline from them and either internally delays them or add more man power to them (or both really). Of course if there are a lot of problems in the pipeline we will get more years of thin game releases. I'd hope however that the wolf and doom games wouldn't face those issues, hopefully the extra year on Starfield and MS already adding more support to that team also helps iron out issues there. They still have a good 5-6 months for that game and even assigning more people now could improve it.
