I Have a 4096mb/s internet speed and can i Play Gta Online Without Lags and what is my Ping In Game ?

Your ping will depend on other things, so we can't tell you what your ping will be.

You may have lag and/or slow loading, as I recommend people have at least 10 mbps for gaming, so you're under that by over half.

Careful how you word things. If you say 4096, you mean kbps, not mbps :)
