Alethes where's that chart from? The only player count chart I know of is Steam Charts, which only tracks PC players on Steam.
Steam Charts peak number of players over the last 24hrs:
- Battlefield 2042 = 4,974
- Battlefield V = 10,567
- Battlefield 1 = 9,849
- Battlefield 4 = 1,328
- Battlefield 3 = 180
As RanzigeRidder2 said, DICE using matchmaking and splitting the player base over multiple game modes and special events is definitely an issue.
I would be playing on PS5 with PC crossplay turned off due to PC having a high number of cheaters compared to console. I'd be willing to console crossplay with Xbox players. PC crossplay only with a PC invite.
That's how APEX Legends handles crossplay. I've read the newest CoD BLOPS 6 game also has console only crossplay. Hopefully game companies are starting to understand their customer preference.
