I just had this happen trying to reinstall 2020 with a 4080s. Didn’t think too much about nuking it as far as bringing in 2020 content BEFORE committing to deleting it…
Anyway, make sure your drivers are updated/functional(likely are fine), and just go to your nvidia(or whichever) control panel and reset everything to defaults. Close out any legacy GPU/Mobo performance enhancement apps and see if it gets past that. I was hitting it in 2020 on re-installation it’s the same bug and not specific to 2024 or any other game. You can find that error attached to threads on many other games.
Ironically I had no issues with 2024, just trying to get 2020 back on. What a dunderhead move I did deleting it before the MP management was implemented, 500gb poof in 20 seconds… Trying to install compatible aircraft outside of MP and the installers kept bugging out trying to ‘find’ the 2020 version to update. Back to a slog I never envisioned being back in again. High probability it’s some tiny setting somewhere the sim doesn’t like on initial installation, that’s likely fine once it’s installed.
Putting in an old card probably usurped the setting/capability the modern card has.
