Just was reading on the 2k steam community that it might have to do something with this:
Confirmed: AVX is required to play NBA 2K21
The 2K Knowledge Base article was updated in the last 24 hours to include the AVX instruction set as a requirement for your processor.
NOTE: In order to play NBA 2K21 on PC, you need a processor capable of supporting SSE 4.2 and AVX.
https://support.2k.com/hc/en-us/article ... quirementsIf the game doesn't boot up at all (or closes after a few seconds of boot), that is a symptom of a lack of SSE 4.2.
If you are not able to actually load into a game of basketball, that is a symptom of a lack of AVX.
There are websites and System Information software where you can check whether your processor has SSE and AVX. Please check those if you are experiencing these issues to help you diagnose the issue.
the point is i have checked my processor with HWINFO and it both supports SSE 4.2 and AVX ... strange stuff
