NZ Player wanting to reduce latency

I recently upgraded to Windows 10, fully forgetting that I had followed a tutorial (here)

which was helping a huge amount to reduce latency. currently I'm getting 300-350ms latency when playing on zodiark. I would rather stay on Zodiark but i noticed it was basically unplayable when going for S rank hunts and though I haven't been charting progress in dungeons, i think the same is happening there. Does anyone have a solution to huge latency?

Im contemplating moving to Tonberry because it has more nz players and the latency isn't as bad (running ping commands through command prompt)

Any help appreciated in advance. Thanks

Hi, have you tried the tool "Leatrix Latency Fix" ?
It modifies your netsettings. Many people achieve to significantly lower their ingame latency tho it has a downside. It will lower the speed loading homepages via browser f/e. Working perfectly to me playing on korean servers.
