I've recently installed FCOM plus some couple of hundred mods to my taste - only to face the infamous "2 Gb mem ceiling CTD bug". So perhaps someone could comment on my mod list and say which ones are the greatest memory eaters in it.

P.S. I have a 1 Gb VRAM card which should be enough for all my texture replacers, so I'm interested in RAM figures only.
P.P.S. So far I've only been to Vilverin and the Imperial City. So I suppose it is some global mods that overload my RAM, the ones that kick in right from the start and not in some particular location.

Are you sure you're experiencing that particular CTD?

Just off the top of my head here at first glance...

RAEVWD and Open Cities.... I know, the two you probably want most, right?

EDIT- After a more detailed overview... UL mods and any texture replacers will be your next largest memory hogs.

EDIT - If you check the OP of my signature, you can get some good pointers
for testing if you are crashing because of a memory ceiling.

No hard facts except I have a regular CTD once every half an hour for no apparent reason. Seemed the most likely cause.

Are you sure you don't mean Better Cities?

I didn't see Better Cities in his LO. OC still uses a good amount of memory because of all the new objects that are moved into the world cell. Though, BC would be much heavier on memory use.

@Elenhil -
Although you make a good assumption based on the timing of the crash, I would take the steps necessary to pinpoint the cause of the the crash. Only way to do that would be to monitor the memory usage of your Oblivion.exe process in your task manager while running Oblivion in windowed mode.

Many people max out there allocated memory for Oblivion by creating hundreds of PC clones in game. Try this while hanging around Anvil Docks or The Waterfront.

I think the command is player.createfullactorcopy

EDIT - Actually, in your case it would be better to play the game normally since you need to identify if you crash is happening because of a memory ceiling or because of other factors.

Open Cities would have an impact on memory usage. What it shouldn't impact on is FPS.

What? I would think that Open Cities would impact FPS, since it moves whole cities into the world, thats alot more AI to process and bog down the CPU.

Yeah, but its still the same amount of AI that is in the vanilla worldspaces, so you get the same performance you would get inside each city's worldspace.

Does in make a difference if I use OC or not if I'm still in IC (which is not open)?

I did. It crashed at 1.4 Gb (the remaining ~0.6 being used by my OS and other programs).

The weird thing is that Streamline does not help a bit even with Streampurge set to 1 (most frequent purges). I thought it could save tons of memory! Could its functioning be affected by OSR?

Not unless you're visiting the Arcane University or Prison Districts.



Doesn't Streampurge conflict with OSR, causing crashes?

Not that I've heard of, purging should be safe to use, you should disable FPSsmoothing, which will convict with OSR's FPS manager and slow motion clamp.

@Elenhil, you could try loading the purge mode to lower number to make Streamline purge more often, or you can force a manual purge with Ctrl + Del

1.4gb sounds about right if you know for a fact you OS and programs are svcking 600mb of memory. It would do you well to optimize the amout of memory your OS uses and stop any services used by background running programs. There are countless guides on how to do this. Just for a quick fix that may help free up some memory try GAME BOOSTER.

Purging memory keeps your memory usage under control within a cell. However, there are certain cells such as Anvil Docks, and the IC Waterfront that can simply fill your memory up so quickly that Streampurge can't keep up. This is especially true because you are using UL and Open Cities. So Anvil Docks for instance is a major memory hog now with UL and OC enabled. It wouldn't surprise me if you are capping out your memory usage within minutes of hanging around Anvil Docks.

Where are you experiencing your crashes? What cell are you in, or what towns are you near? Based on the amount of mods you have loaded, it wouldn't surprise me if you crash anywhere within the world space.

EDIT - If you haven't already done so... Try lowering your uGridDistantTreeRange and uGridDistantCount. Lowering uGridDistantCount help reduce the major memory usage hit from RAWVWD. Try playing with the fog settings within Streamline's .ini file. You can still balance out your game to look realistic by getting creative with the fog distance amount in Streamline and the amount of visible distnat LOD trees. I don't have a link for it off hand, but Arthmoor and Tommy_H had some handy tips for this. I will try to dig up that thread.

Strangely, OSR thread does not mention it, only recommends to set Streamsmooth threshholds at least 10% higher that OSR ones. By the look of it, it works - Streamsmooth handles most of FPS stuff via game settings and when it still drops below its lowest margin OSR kicks in with slow motion etc, working by entirely different ways.


I already set it to 1, that's the thing that surprises me.

If the problem is VRAM related, then you'd have something here, though RAEVWD's impact on VRAM isn't much more than about 50MB additional space.

Open Cities will be even less of an impact on that because it uses vanilla assets and would only be an issue in combination with texture packs. Otherwise it uses the same amount of resources as the vanilla game. Unless you're in the new Leyawiin, but even then, you're going to have far more influence from FCOM and other AI heavy mods on the system RAM pool.




The impact on memory usage is negligible. The FPS hit is a phantom which I really shouldn't still need to keep addressing

As far as AI, there aren't any more AI's than normal. The game is tracking the same amount of NPCs it always has so that's not a factor.

Pretty much so. Especially in Waterfront


Already. Currently trying to see what difference removing OC does.

What are the hungriest mods, then?

I always thought that texture replacers like QTP (Redimized in my case) affect VRAM, not RAM. Is that so?

@Elenhil - Regardless if your Physical RAM or VRAM is the main culprit towards hitting your Oblivion.exe memory process ceiling, you really don't have enough RAM to run that large of a load order. So your CTD's are imminent. You could prolong them a bit more by freeing up your OS and background progams memory usage as I explained before, but you're only looking at extending the amount of time before you reach that memory ceiling. With a good PCB mod like HTFPCB Extended, you could set it to run a PCB every 10 seconds. This will add to the lag and stutter of your game, but it may be the only way to prolong your memory ceiling CTD enough to enjoy a decent length of game play time.

Your 1gb of memory is fine. Windows will start using available system memory for VRAM as backup, although you will notice additional lag and stuttering start to occur once this happens. You should monitor your texture memory usage while in game. Type tdt in the console and hit enter, then type sdt 13 and then hit enter. Having this open along with your task manager to watch the memory usage of the Oblivion.exe process will help give you more insight on how much total system ram is getting used up while you are playing.

Texture replacers mostly use VRAM yes.
I mentioned texture replacers as a culprit because if you exceed your VRAM dedicated amount (1gb) then Windows will start to use system memory as VRAM


Your hungriest physical RAM eaters are

RAEVWD, UL and OC , IMO.

The hungriest IMO is RAEVWD.

You will notice some improvement loosing OC, but probably not as much as the other two mentioned above.

EDIT - What OS are you running?

Checked that out with sdt 13. VRAM usage below 800 Mb prior to CTD. That rules out texture replacers, I guess.


Windows 7

Yeah, it's a fairly safe bet that VRAM isn't reaching past dedicated.

Windows 7 is system memory hog obviously. Is it 32 or 64 bit?

This guide can help reduce memory usage for Windows 7... http://www.blackviper.com/Windows_7/servicecfg.htm

I'm curious as to how you're arriving at this conclusion. RAEVWD is strictly mesh+texture which affects VRAM. The UL mods would only factor in if you're in those areas, and OC is no more memory hungry than the vanilla game.

You do realize the game buffers in the memory of whatever is immediately behind any load doors that get popped into the local space? So the data from closed cities is still in system memory even when you haven't gone inside, right? It's part of how the load screens aren't very long since it doesn't have to load nearly as much as it would if the entire buffer memory was gone.

The only way it becomes an issue is if the purge scheme you're using is set to empty buffers on passing through a load door, but in that case it only comes into play if you're leaving the city.

I may be wrong, but I'm just basing off of memory which mods I noticed the most dramatic impact of physical memory use. You are correct about UL, my guess is his crashes would occur in the more memory intensive areas. Chorrol Hinterlands would be another fair CTD bet. I'm under the impression that his game is overly stressed for physical memory period. His load order is amazing for the amount of ram he has installed. On XP, he might get away with it for 2 hours of gaming, but not on Win7 it's a different story.



I would be willing to debate against that. Yes, it's true that data is cached into memory after having entered a cell. What data is cached, and how much is a entirely different story. I can't prove what data is and isn't cached as I'm not home right now. But I highly doubt all of it is, because that would create near instant load times. In a small interior cell, that may be the case on most systems. But that is only because there is less data in that cell. But for a whole city, that's debatable. With OC, city data is constantly loaded as long as that cell is in your loaded space. I know you have defended OC's performance hit for a while Arthmoor, and I agree with you on most plains about it's low performance hit. However, I would need to test for myself and see the numbers to really be a believer of your defense on this one.

Any legit test would need to account for LOD (both color and normals) as well as other replacers. And have two people compare with the same set of each.

Say a person was using Qarls 4096 compressed Normals and a decent color replacer, as well as, texture replacers for architecture and clutter and landscape and ... hi res HGEC skin replacers, and clothing replacers ... all that adds up and when you then take a city space that has all that information in mass and smack it down into the wildness where it will have a heavy impact if your rig is already sweating the wilds.

That said - there is nothing that hits my system harder than FCOM - it is the single (well combined) biggest drain on FPS in my very extensive load order.

To Arthmoor's credit he actually does work at keeping his own load order based on performance and last I knew was very light on overhauls (basic FRANS and TIE) ... not trying to talk for Mr. Arthmoor here - just as I understand it.

In short, It does make a difference what you run OC with.
