I've noticed several instances of fog volumes popping in and out across levels, like seen here in the second circle from the left.

I know this is an older post but I can confirm most (if not all) of these are behaving this way. Don't know if this is something that would take up to much space if ever fixed or even if this is LE1 Patches problem to fix but just confirming nonetheless.

The entire diplomat office area at the embassies (BIOA_STA00 Start_STA20_08) is streamed in/out too early at the door that leads back to the embassy lobby (BIOA_STA00 Start_STA20_07) and the issue is clearly visible due to the office door automatically opening and having a large trigger area. This is fixable by setting BIOA_STA20_08 as a visible chunk in BioTriggerStream_140 in BioA_STA00.pcc and removing it as a loaded chunk in the same export.

Looking out of the office to the right, the door and button for Pallin's office and a light fixture next to the bar door are also not loaded in (BIOA_STA00 Start_STA20_09). This is fixable by setting BIOA_STA20_09 as a visible chunk in BioTriggerStream_94 in BioA_STA00.pcc and removing it as a loaded chunk in the same export. This way, one does not have to modify and ship BIOA_STA20_08.pcc while only rendering the layout and placeables of those rooms without the actual NPCs

After 7 days I've managed to fix a majority of pop-in issues.

I've decided to just concentrate on things that I can fix using streaming states in order to avoid having to modify tons of files like in my initial approach in February. That way everything is limited to the *_00.pcc files of Ilos, Virmire, Feros, Citadel, Therum and Eden Prime. Noveria did not have any noticeable issues. As for any popping related to LODs, I've left untouched because it would necessitate modifying other files and would be detrimental to performance and isn't too drastic as the other stuff. The end product also didn't go over the 6GB memory limit that I set out for myself.

Along with this approach I've also fixed several loading hitches related to improper streaming setups from both OT and LE. And I also increased the amount of visible chunks on the Citadel at any given time, most notably in the Presidium, in order to increase detail over distance, such as NPCs that are within render bounds and minor objects like benches. The change Presidium "extension", according to my testing on my rig, impacted performance by an average of 10 frames at half of the locations within the Presidium when looking out into the entirety of it with Vsync disabled and a framerate cap of 240. Given the increased detail, I feel that sacrificing that amount of FPS is within margin. I've made sure to only add what was necessary in order to not add miniscule details that wouldn't be visible even by the minority who'd see it pop.

Here are a couple of issues I've encountered:

• Feros' Geth Ship destruction cutscene's skyway is visible through the holes in the ceiling in the room with the clamps. Hiding it would require restoring the bloom plane that originally covered the ceiling hole or restructuring the specific BioTriggerStream so that it doesnt load the entire contents of the chunk and therefore excludes the cutscene file from being visible until it actually plays.
• Several instances of being able to see parts of Feros' level from outside in due to missing bloom planes or other could not be resolved with streaming changes except for a floating skyway visible through a large hole in the ceiling of a stair case that precedes the room where you destroy the Geth ship
• At the ExoGeni survivor camp, the assets of the skyway leading to Zhu's hope visibly pop as you approach/leave the door thats obscuring it in the form of skybox towers and smoke particles visibly popping through the window next to the door, as well as minor geometry at the right lower corner of the door's frame. This was not fixed due to the outer model of the tower youre in being part of the same file and being visible inside the tower and visually partially obstructing the camp and road going up the tower if the file is visible inside the tower. This would require relocating the object into another file or changing the bounds / adding a new biotriggerstream specifically for the tower exterior model.
• Debris flying over the level during the endgame's citadel tower exterior portion is tied to specific chunks in position and streaming. Fixing the debris may require reworking several files and possibly the debris itself, then adding the debris into a global file for that section.

Patch Notes:

• Fixed any loading hiccups during normal active gameplay
• Fixed most instances of obvious level chunk / object and environmental popping (LOD based popping untouched due to performance reasons)
• Fixed Normandy Airlock interior being visible from the outside on Feros
• Increased amount of visible chunks on Citadel to allow for seeing detail such as minor objects or NPCs from a further away distance
• Increased amount of environmental detail (foliage, rocks, smoke) for Eden Prime landing cutscene
• Made Flux NPCs and furniture visible during the cutscene where Schells is tossed out
