I can faithfully recreate my plummeting fps without dying by zoning into Shornhelm. Let me elaborate.
I can ride my horse through Cyrodiil (Dawnbreaker) and get 20 to 27 FPS. If I approach a battle and let the toons render off in the distance, my FPS drops to around 13 to 17 and stays that way as I get closer and closer. At 13 to 17 I can actually participate in some fighting. Its tough and not really functional, but I note that here as a baseline.
However, if after a battle I am standing outside the keep, my frame rate is cruising at 24 to 32. I'm just standing there so no duh. Suddenly the zerg comes over the hill. Fifteen or twenty toons suddenly need to be rendered right in front of me. Frame rate drops to 3 to 8 fps until I die (which is no more than five seconds since I cant retreat at that frame rate).
Now as for Shornhelm. If I'm standing next to a wayshrine in say Ali'kr Desert, my frame rate is zooming (cough) at 20 to 27 fps. I zone to Shornhelm.
For the next two minutes and a half, my frame rate drops to 5 to 8 fps and one by one each toon appears. Since no one is killing me and rushing off the screen I can watch my frame rate struggle. After all the toons are rendered, Shornhelm gives me 13 to 17 fps. Enough to craft and bank.
Can anybody use this data to help me make some changes to what I'm doing? Do I have to change ISP's? Do I have to change how my network is set-up? Is there some tool I can use to see what traffic is killing me?
I'm on a laptop with a GeForce 460M. Not great I know but it was doing fine before 1.2.3. I ran High graphics, with Firefox and mumble open, twenty addons through several public dungeons and cyrodiil keep battles.
Now I run low graphics, only four addons, close everything, shut off sound, set eso.exe to high priority and yet I am still hosed.
What the heck can I turn off from 1.2.3 so that I can get back to where I was?
