Lag spikes in instances but no latency increase?

[Underworldhades]

I have created the thread on General discussion without realizing it, so creating this one here now, idk if it would cause an issue, but on to the issue:

Hi, I started back up a month ago, and it was fine until a week ago when I noticed that I get lag spikes whenever i start doing instances, whether its raids, dungeons or trials.
Now, the odd part is that my net is fine. I would look at the top right and it would show "0" on receiving YET when I look at the resource monitor on my other screen it would still show actual numbers. and the latency would be normal.

This is the resources Im seeing when that "spike" happens: https://i.imgur.com/oZxOmvA.png

Can anyone help me figure out what's going on and how I can fix this? Thank you.

For about a week I've been getting frequent lag spikes in FFXIV (and only in FFXIV) as well. This happens out in the open world as well as when in duty instances. Obviously it's going to be more noticeable in instances as there is constant action happening there. When it does happen in duty instances it usually results in an 90002 error along with a disconnect.
