Hello, I am from Gurgaon and I recently got a new breoadband connection from YOU broadband India. It is cable and both the download as well upload speeds are 1 mbps. The connection is good and stable for surfing and downloading but I can't play counter strike 1.6 as my latency (ping) spikes when I shoot or I guess it spikes after every 2-3 seconds. Generally the latency is 40 to 80 but it spikes to 150-250 sometimes 300. I formatted my system 3 days back and have checked it for malware, spyware and viruses and found none. I have a Nvidia gfx card and Vsync is turned off. Is there any solution to this problem. Please let me know if anything needs to be done from the ISP's side. I can try to talk to them. Please let me know if any additional information is required from my side.
