LOL. Trouble is that this HFC stuff is science. It's amazing it works at all!
The upstream channel (you've and the others on your node have got access to 1 upstream channel) is organised into timeslots for which your modem can bid when it needs to send something upstream. When you gain a timeslot, your data up to codeword size goes into the opportunity given by the timeslot. For gaming, the amount of data per request is very small, but the requests are very frequent as you move your mouse or shoot the peasant.
If your area/node is oversubscribed or heavily utilised, your timeslot opportunity doesn't come up as frequently as you need it, so there is lag and jumping around etc.
The solution, as Igni points out, lies in resolving contention at the node end. He said (and this is what the CEO needs to take on board):
Could take another channel from the legacy network and either bond them or run them as a single 6.4MHz channel. Could also clean up network some more and/or use better upstream PHY migrating everything to DOCSIS 2 and use previously unusable frequencies for SCDMA / 16QAM TDMA to add additional capacity.
Reducing node sizes or upstream service groups further will have the effect of cleaning up networks, at present a number of overlay upstreams span more than one node.
These would produce considerably more capacity in the same RF space.
HTH.
