Xbox series x 2k 120hrz support

What you are describing sounds like a lag or latency issue to me, and not a problem with the controller itself. To test this theory I searched 2k19 lag issues and found a 2K series Network Troubleshooting Guide at support.2k.com . It seems you are not alone
in expieriencing these issues within 2K series games. A number of players across all platforms seem to have the same performance issues when going live. I would reach out to 2K for support as well as it seems the issue is within the 2K series games.

Nba 2k won’t support crossplay on Xbox one the developers unfortunately said it’s for Xbox series and ps5 consoles only

Sorry but 2k has not announced cross-play for the game.

Since you have to pay for the game separately on both consoles I doubt they will have Xbox One and Xbox Series X crossplay.

Before someone says If you buy NBA 2K21 Mamba Forever Edition you get the Xbox Series X version. Yes, that edition bundles both the Xbox One version and the Xbox Series X version but is not a free upgrade or the same game.

Yes

Series x

No

Yes headset dongle

Only after the 1st quarter in 2k rec games… no other mode at all

I wanna know how can I transfer my 2K myplayer from current version to next gen I went from x box one to x box series S
