Internet connection on testing

4723Kbit/sec
364Kbit/sec

I've posted on their website but sadly they think its my router causing the interference...........................................

That is highly doubtful. Yes it is slideshow lag, not warping lag.
Only thing I haven't tried at this point is full reinstall of said game, or full reinstall of Windows. Unless someone, much like the topic stated, might know a needle in a haystack common video performance loss misconfiguration or something to that effect. Or a benchmarking 3d tool that isnt 500mb and costs money that I could try to see if the hardware is failing or slow at any point. However according to performancetest, it seems to be fine.

I'll try reinstalling the 4gigabyte game from scratch next, as it seems much like on the mmorpg forum, everything has been ruled out. It has to be software, right? If performancetest says hardware is reasonably good, and nothing was "dramatically" low, and the internet connection is fine... then... it has to be a misconfiguration somewhere.
