I guess you're trying to get stable 1000 fps server? For that you need Dedicated Server, I don't think VPS will do the jobI have a VPS on openvz . bought from ovh game Provider. Still testing it at the moment.
Need to upgarde 1000hz on linux kernel Debian 8.x 64 bit OS .
Can you guide me if its possible and if yes what are the steps needed to accomplish it
Thanks.
