Yes, I have the same problem too. I started playing tanki about 2 weeks ago and thsi issue started creeping slowly about 3 days ago. I can be playing for 2-3 hours with no issues and then it would start happening. I have a fast internet commections that gives me 60 Mbps down and 12 Mbps up. I have a single 4core XEON W3565, 8 GB Ram, and a Quadro FX 1800 video card (not the best gaming card but it can hold on its own). The video card stats show temp around 65 C (seen it as high as 77C on prolonged play > 60 min, Card specs uper limit temps is 90C so it is within limits). Utilization: GPU 30% -70%, Frame Buffer 15%, Video engine 2%, Bus Interface 2%. In other words, the card is not stressed palying this game. Perhaps the dvelopers can find a solution as it seems that this is not an isolated case. I do not know if we are the only ones having this problem or we are the only ones complaining about it. Tanki is a great game and any help is appreciated.
