help with memory settings. unsure

[domjam]

hello im confused about memory settings.  im not sure if I understand it correctly  is this correct? i have 16gb of ram a 6gbs of vram on my graphcis card.

 

[MEMORY]

ExpandSystemMemoryX64=true

ReduceSystemMemoryUsage=true

DisableDriverMemoryManager=true

DisablePreloadToVRAM=false

EnableUnsafeMemoryHacks=false

ReservedMemorySizeMb=258

VideoMemorySizeMb=6144

EnableCompression=false

AutodetectVideoMemorySize=false

Try this:

 

[MEMORY]
ExpandSystemMemoryX64=false
ReduceSystemMemoryUsage=true
DisableDriverMemoryManager=false
DisablePreloadToVRAM=false
EnableUnsafeMemoryHacks=false
ReservedMemorySizeMb=256
VideoMemorySizeMb=6144
EnableCompression=true
AutodetectVideoMemorySize=false

[MEMORY]

ExpandSystemMemoryX64=false

ReduceSystemMemoryUsage=true

DisableDriverMemoryManager=false

DisablePreloadToVRAM=false

EnableUnsafeMemoryHacks=false

ok thanks im still getting horrible stuttery lag  just in vanila skyrim with this enb? im sure this should not be happning. any ideas whats going on? i get solid 60fps with it turnd of.  the enb is Natrule lights and atmosphirics v1-4 with the skyrim enhanced shaders NLA.  im using a 980ti

What is your FPS with the ENB?

[domjam]

well i installd alot of 4k textures since then. and testing right when you exit the cave at the bigining. my fps with it of is still 60fps. with it on  its around 50-47-45 but there is a horrible stutter present.

[phazer11]

The horrible stutter is ​from      the 4k textures (if you have them in the landscape) most likely. Skyrim doesn't tend to do well if you have more than 1-2k landscape textures unless you have TONS of VRAM (like 6-8GB)

He's on a GTX 980TI, which has 6gb VRAM I think.

 

From the looks, your VideoMemorySizeMb is too low. Did you follow the instructions here to get your 6GB number? https://wiki.step-project.com/ENBoost#tab=Recommendations

 

You might play with ReservedMemorySizeMb as well.

 

Or do you really have a GTX 980TI in combination with very little actual RAM. If so, it sounds like your problem is not enough physical RAM.

[TechAngel85]

VideoMemorySizeMb is fine. It's not used until it's needed anyway and this setting only tells ENBoost how much memory it can use; it's not how much it will use unless textures are freakishly maxed out and are using all of it up. Since 4K textures are being used, set ReservedMemorySizeMb to 768 (you'll have to play with this value). Also, you'll probably want to up your SKSE vales from the default. This you'll have to play with as well. Currently mine are set at:

 

[Memory]
DefaultHeapInitialAllocMB=896
ScrapHeapSizeMB=256

 

Never adjust ScrapHeapSizeMB away from the default because it never uses more than the default so you'll just be wasting memory by doing so. Unfortunately, every system is different so it's going to take some enough on your part to test out different value until you achieve a smooth game.

I think he said he was having trouble with stutter, not CTDs.

[TechAngel85]

Two birds, one stone.

I have a similar problem, I'm also unsure.

I have an older computer with 4GB of RAM, but under 'System Properties' in Control Panel it says I only have 3.25 GB of RAM.

I'm just installing a new 2 GB video card.

So I'm uncertain if VideoMemorySizeMb = 2048 + 4096 - 2048 = 4096

Or should it be something less

Maybe 2048 + 3072 - 2048 = 3072 ?

Thanks for your help.

[TechAngel85]

Some of the RAM is probably reserved. Use Total Available Graphics Memory - 170 (for Win7...for Win8+ minus 350).

[aristotle]

Thanks for the prompt response.

I still use Windows XP.

The 3.25 GB is "usable RAM", I think.

[TechAngel85]

Just use Boris's tool: https://enbdev.com/download_vramsizetest.htm

 

He still runs WinXP too so you'll be fine. Subtract 170 from the number it gives you from the DX9 executable.

Try this:

 

EnableUnsafeMemoryHacks=true

 

The only way I can use ReduceSystemMemoryUsage=true without horrendous stutter is to use the other setting.  It is this way for a lot of people - I'm surprised this wasn't suggested yet...  While it's better to see if re-adjusting some of the other settings solves the problem first, it just may well be that the only way to solve it is to either set EnableUnsafeMemoryHacks=true or set ReduceSystemMemoryUsage=false.  At least to try to see if it works, since quite a few people need to do this to remove the stutter introduced by ENB's memory handling features for Fallout New Vegas.

 

EDIT:  Oops.  I was thinking this thread was in the Fallout New Vegas forum...  :)

[TechAngel85]

You only want to enable that as a last resort. It's called "unsafe" by Boris for a reason. ::
