Lag when turning camera around [FIXED]

[yag1z]

It occurs every time when fps under 50. It doesn't happens with high FPS like 50-60. I don't know what causing it even I have high-end machine for Skyrim.

I have 2GB VRAM(gtx680mx) and I am using enb with 2k textures for most of the things  but it does not pass the VRAM capacity. Game uses  around 1900-2030MB of VRAM,

2GB of VRAM is not very high-end IMO. How noticeable is that "lag"? Is it just a fps drop while you move the camera? does it persist for a while or until you move the camera in other direction? It coul be the usual frame drops you get by looking at some places (with trees/bushes/buildings). You can always try to play a while with just enboost and no/minimal texture replacers to see if there is any difference.

in 2012, 2GB gtx680 was earlier version of gtx1080 and was high-end card considering skyrim realised in 2011. It is still great card for skyrim runs 60fps without mods and real problem is starting here; When turning the camera  It suddenly drops to 20fps and happens everywhere even in empty areas(ex:whiterun tundra)

 

*EDIT* at the same time fps drops from 40 to 20 when changing weapons  and persist for a second.

@Sternum is correct. 2GB of VRAM is not 'high-end'. Especially if you are using an ENB. Which ENB is it?

 

How long have you had the problem? What has changed?

 

Whiterun tundra is not 'an empty area'. It is full of grass and plant textures for starters. Grass density, wind speed, shadows - all these and more will make demands on your resources.

already said the game is not even use 2GB VRAM with 2k texture mods+enb my game uses 1980MB of 2048MB vram and I am using Suki enb.

 

When I was not using enb the lag was still there however only appeared when riding horse now I am realy tired of it. Played game like this since 2013.

I assume you are using something like Skyrim Performance Monitor to get the VRAM usage? I'm also assuming that you don't use many mods.

You haven't 'played the game like this since 2013'. In 2013 you didn't have Suki ENB as it only came out in 2017.

With 2GB of VRAM and an ENB even with a limited amount of mods you are making demands on what it can do. If you sweep your mouse around on the Whiterun tundra then all the new grass etc which comes into view has to be rendered.

Try going in a small room, e.g. an inn bedroom, and turn the camera.

I am using Rivatuner for monitoring.The lag happens without enb too.Ridiculous thing is without enb It only happens turning the camera while riding a horse.

 

And yes it only happens in outdoors.

Yes, it is a 2011 game. But you're adding textures, meshes and other stuff through mods. And on top of that post-process effects via ENB. So you're just pushing the limits of what your system can do. I'd recommend you to try other enb presets and maybe change your textures for others more performance friendly.

tbh stating you have a "high end machine" in 2019 when your post was made then telling us your specs are for a 2011 card isnt what we call "high end machine". BUT that isnt important as you also didnt really mention your ram or cpu as it could also be those as well.

of course it don't use more than 2gb

how is it supposed to use more than what you have?

textures.bsa is about 1.5gb (you can't ram ctd without mods, there isn't enought to load)

 

most texture in there are 1k, if that's optimised, it's 700 kb for the diffuse, 1.4 mb for the _n, 2mb each texture

in those dds, you have the 1k texture, the 512*512, the 256*256 and the 128*128 (mipmaps that replace full resolution when too far from it), about 30% of the dds size

 

you can get about 650 1k texture load in a gpu that have 1 gb (it's skyrim minimum?)

that's 1.4 gb in your ram, and with all dlc, your skyrim.exe is about 2.2 gb, you can't ram ctd without mods

 

you install a texture replacer, 2k, that replace about 10% of those .dds, but let's go crazy, everything 2k, in your gpu with 1gb vram, you can load 158 2k textures

that's 1.3 gb in your ram, it still not enought to ram ctd, even with 100 mb of .esp

in town, you can need more than 158 textures, you start seeing purple

 

 

 

 

of course the game use 2gb vram, everything is load in it, until it's time to unload unused texture to load newer textures

and that's the performance drop

 

either because cpu is too busy with unoptimised crap to tell what to render to the gpu, so the gpu wait to know what to render

either because the harddrive can't keep up, and if the gpu have to wait for the textures to render stuff, 0 frame are rendered while it wait, so frame per second drop

either because there isn't much ram left to load newer textures, so cpu have to unload unused texture to load newer ones, it will unload to load newer textures when you turn around, and again, unless you ram ctd

 

a 2gb gpu isn't a problem with 2k texture replacer, it become a problem with npc mods with those custom race, that need much more ram

an enb isn't a problem, if it come with a 4k sun.tga or other performance hungry stuff, then it can the fps much more than the others

hundred of mods isn't a problem either, depending on what they are (40 custom race followers you keep around you, that need a lot of ram, dozen of quests mods, if there's a few ones as crappy as heartfire, you are running a lot of stuff for nothing all the time now)

 

the only way to find out the bottleneck, is to run skyrim performance monitor, and check what can't keep up when fps drop

gtx680mx and 2048MB vram would suggest onboard graphics.

[yag1z]

Bros and sisters everyone talking about things that they don't know. I said ten times the game using around 1900-1950mb vram and my vram is 2048mb  still free 98MB. Also when this lag happens my game uses %85 percent of my GTX680mx. If you don't know what I metioned please don't be a placebo.

Your system uses ca. 1950 Mb because there is no more memory available.

 

Example: 1 uncompressed texture (dds with 4096 x 4096) is about 85 Mb in size.

However, the game does not load all existing textures at game start, but only the "visible", depending on the angle and distance.

And your laptop graphics card is too slow to erase "unnoticed" VRAM textures and load new textures.

So do not use mods / replacers with large textures, any "standalone" followers and reduce the view distance in the graphics settings. Additionally, check your ini's for Lod, Trees, Grass etc. and setup your ENB.

Fast Answer:

Configure your ENB properly.

Open EnbLocal.ini and up ReservedMemorySizeMb from 64 to 128 and test.

If the lag or the stutering persist up to 256. Bigger values are not recomended.

https://wiki.step-project.com/Guide:ENBlocal_INI/Memory#ReservedMemorySizeMb

 

Long Technical Answer:

Spoiler

A video card with 2048 mb of Vram is not enougth for play skyrim with 2k HD textures.

When you turn the camera the game must show diferent mesh and textures and the video card need discard unused data for have space in the Vram for the new mesh and textures.

That work is made by ENB and use a buffer of the size specified in ReservedMemorySizeMb of 64 mb by default.

 

That size is enougth for the normal game but is not enougth when you use 2k HD textures.

A small buffer mean that ENB must make a lot of rounds for transfer the mesh and textures and you can have lag and stutering.

A big buffer alow ENB transfer the mesh and textures much more fast.

 

But as you can read in the web page, the ReservedMemorySizeMb is taken from the real Vram of the video card. If you have 2048 mb and put the value in 1024 you are putting half of your Vram in buffer. That is a waste and can give you other problems. Put the value in 512 is the 25% of your Vram and that is another waste but can works.

Is better use 128 or 256. If the lag persist, maybe, your problem is not in the ReservedMemorySizeMb and we must search in other side.

 

Aditionally, for your information, the memory used by the video card never can up to the maximun posible value of 2048. The video card need space for swap textures and compute effects and the ussage of the Vram is dynamic. Never can up to the maximun.

The same thing happend in your computer. You can have 8 gb of ram but the machine never use all of them. Always have a small block of free memory for make swap with the virtual memory in the hard disk.

Additionally I am using 4k textures only for characers and npcs 2k for landscapes&misc now I am going to try to compress my 4k textures to 2k

it's you that don't know what you are talking about...

 

you always have 100 free mb, because gpu start unloading unused texture before reaching the max, to not have to do that when there's textures to load

you will only reach max vram usage when you see purple in game, because you don't have enought vram or ram (gpu can't load textures from ram if they aren't in the ram)

 

gpu usage is supposed to be 100%, if it drop under 100%, gpu isn't fully used because of a bottleneck

 

nobody can find that bottleneck from some blabla "ouin ouin my fps is droping", if you want to do something about that, run skyrim performance monitor, check what reach max usage when the fps drop, and do whatever have to be done about that

These people do know what they are talking about.

You on the other hand appear not to know the meaning of the word 'placebo'.

A PC with 2GB is insufficient to run modded Skyrim with an ENB. With a lappie or notebook - more so.

[yag1z]

I know what placebo means however this is not the topic

 

 

Fixed the issue with texture ordenator compressed some 4k textures to 2k. Tweaked enb vram settings. Now vram usage  1700-1800 mb

In other words, the people who didn't know what they were talking about, knew what they were talking about.

 

Just for future reference, most things that come with 4K textures also have a 2K option or at least some sort of 'performance' option.
