Regardless, the remaster appears to have been rushed out due to increasing leaks, no? It's hard to believe that with the technical issues the release was actually intended to land in April 2025, instead of fixing issues until March 2026 and releasing it as an anniversary remaster.
I don’t care for Oblivion but I hear the remaster crashes a lot, whereas I’ve had 3 crashes in 400 hours of Starfield. Two of those crashes were BSODs that Microsoft was responsible for. Maybe the Oblivion remaster’s instability indicates they will stick with Creation 2 in TESVI: I was skeptical that UE memory management was a good fit for BGS games’ complex global state. My suspicion is that Creation 2 uses multithreaded scripting, and Starfield on release had some odd bugs suggesting dangling threads (e.g. NPCs which stayed stuck on “busy” and couldn’t be interacted with). But in recent updates they’ve hammered a lot of that stuff out.
[1] Obviously Microsoft has a strong incentive for console exclusivity but the other side of this is that BGS games always sucked on PlayStation. Morrowind was also PC/XBox only, and Bethesda’s roots are in PC development.
