So my brother & I both use our consoles (ps4) simultaneously. He plays SFV and I play R6 Siege; every time we do so one of us lags and the other has decent ping (in siege I get around 20-30 ping [there are ping spikes that make it difficult to play]) I understand SFV uses P2P, but it's also noticeable when streaming video. The quality goes down briefly, but then goes back up and this happens many times.
Just wondering what could I possibly do to get far more consistency with the connection.
The anti-buffer is at 65/65
both our consoles are prioritized
geo-filter is set to spectate for him and filter for myself
UPnP is on
Perhaps it's something else.
