Anyone know what effects the betfair live feed latency, and how to improve any lagging??
I watch the BF racing, and the odd German / South American football live feeds with no problem at all, maybe a 1 second delay. But when it comes to tennis live feed... OMG it keeps stopping and then skipping forward to catch up the the present. Its soooooo anoying when a player is about to serve and it freezes mid racket swing... and the stopping and starting isn't good for my mentality

I am using my mobile to tether to my PC, not ideal I know, but am receiving 80-100+ mbps download and 50-80mbps upload, testing on mobile and desktop browser Google speed test. Looking online and BF recommend a minimum of 1mbps. Not sure how old that info is.
My average ping rate to betfair.com is around 60ms, and the recomendation is below 100ms. Check!
I am running BA on a recently built gaming rig, with a ryzen 5 cpu (6cores, 12 threads), using M.2 hard drives, 32gb RAM.... the only thing thats letting it down atm is the graphics card, being an old Geforce GTX 650 2GB which I was thinking could be the issue, but the problem only seems to be with the tennis live feed, and as I am within the recommended specs with everything else I am wondering if its my end or betfairs.
I do need to upgrade my graphics card to something with more memory, and am currently on the lookout for a 5G phone to see if this solves things... But I am not convinved that it will.
I have also tried watching the tennis live feed with nothing else running on my PC and it makes absolutly no difference.
Any ideas will be appreciated.

TIA
