So I got to an area with pretty terrible performance last night... eastern shore, ~middle of the map. The very dense area around the Old North Church, Faneuil Hall, The Shamrock Taphouse, etc. FPS isn't the issue. I can maintain 60 by lowering shadow distance to medium; however, I get these awful hitches whenever the game loads a new cell. FPS drops to 20-30 for about half a second every time it loads a new chunk of content.
A similar thing happens in Lexington and other dense areas, but out in the wilderness it's smooth. I ruled out a ton of stuff last night trying to find the culprit. Did a fresh install of the game with default .ini files (didn't have any tweaks anyway), closed RivaTuner/Afterburner, put all settings to low, disabled SLI, ran the game in borderless windowed mode, tried various methods of vsync (game, ENBoost, nVidia CP), moved the game over to a different HDD (5400rpm HDD... the game is normally installed on on a raid0 of 500gb 850 Evo SSDs), and tried increasing/decreasing pagefile size. Nothing helped. The only thing that affected it at all was installing on a different HDD. It was noticeably worse which really makes me think that it's somehow related to storage.
I was certain that borderless windowed mode was going to fix it. Since for whatever reason the game takes 3-4x longer to load in fullscreen vs borderless windowed I was thinking that the same was happening for loading in new cells. No luck though. RAM speed is another thing that seems like it could affect this. I have 16gb of 1600mhz DDR3. I'm wondering if overclocking the RAM would help.
Can anyone provide some insight on this issue? Does anyone else experience this? Not going to lie, it's making me not want to play the game. Though with Bloodborne DLC on the way I'll be taking a break anyway. Maybe a patch or two will help.
