Ok, let's try. But i don't think writing this here will solve the problem. Already posted in some other threads about this (in part).
First, I am having lag spike issues during combat. NOT versus player (not tried that, low level) but against monsters and npcs. If i use a "fire staff" many times the fire comes out of the staff some seconds later. Sometimes i push the fire button 2 or 3 times, i move, nothing happens, some seconds later i see the enemy dead (killed by my fire shots). If i use the third person view, if i keep moving, i can see the shots going from where i WAS to the enemy. This happens almost every time. Not only with magic but with swords and alike too. I noticed lagging in emotes action too.
I've tried everyhing. Fresh windows install, fresh TESO install, Repair, opened router ports, changed all the graphics i could (d3d,opengl, various settings), firewall, dns, compatability mode, administrator mode, with or without launcher, etc. Checked my latency/ping during gameplay. Always way under 100. Fps in game from 30 to 60.
Reading in forums (official and not) i can see many people having this problem.
Another thing, which may be connected or not, sometimes i can't see objects and they appear late, or not at all (npc, tables, books, etc.). See attached files.
Sounds too have some delay. Not always, just sometimes. Mainly in combat, but even when i use the inventory (or other things) sounds are a lot LATE.
/reloadui does not fix anything.
Thank you very much, have a nice day.
