DynDOLOD 3.00 Alpha 182

Thanks Sheson, Just found this out on my own as I installed USSEP and that error went away. I just got back to edit this when I saw your answer. I have no messages anymore and that's after do the CC downloads. All good and thanks again.

I apologize in advance for this post and want to thank anyone in advance who replied to this thread. I am pretty desperate to get this working. I have some screenshots of the FPS/Frametime to show what I am dealing with. I have also posted the same topic on Reddit for additional help.

So my Skyrim has been plagued by an unplayable stutter. I have spent close to 100 hours trying to troubleshoot this issue myself. Basically, my Skyrim will be smooth and perfectly playable for the first few minutes. After a few minutes, it becomes a stuttery mess.

Now this stutter does not appear to be loading stutter, which is actually pretty surprising for how many mods I am running. I had Skyrim Performance Monitor running and saw that the I/O graph looked pretty normal as well Example.

This stutter is just constant when you are moving and is unplayable. If I stand still and rotate the camera the FPS/Frametime is just fine.

Before I ever started modding my game, I made sure that it was playable and smooth and stable. I basically run in a giant loop to do this. My test run takes me from the exit of the cave from Helgen down to outside of Whiterun, east towards the soutside of Riften, then north up to Windhelm and then to Winterhold and west to Dawnstar, then to Morthal, and then across the swamp to Solitude and then finally follow the road back to the cave outside Helgen. I never stutter, hitch or anything on vanilla Skyrim. This tells me that my ini files should be okay. I even tried running at 2.5x speed to make sure I didn't get any stutter.

Now for my testing here with my screenshots, I am only running to the southside of Riftens gate and I am running at 2.5x speed to test for load stutter. The stutter is pretty much the same whether its 1x speed or 2.5x speed, its just a tiny bit more spread out on 1x speed.

All Mods enabled WITHOUT DynDOLOD

Through my troubleshooting I have narrowed it down to DynDOLOD as the culprit or at least somewhat responsible. I am not sure why this is. I have tried to use the reddit search and google specifically for DynDOLOD stutter and there really hasnt been anything in a few years. No one else seems to have my issue or at least comment about it. I have tried just about every setting in DynDOLOD from Low to High to removing the Ultra tree LOD and grass LOD and nothing seems to help. If I run DynDOLOD on the vanilla game with no mods, it will run close to perfect. I get a few little blips on the frametime graph, but I cannot feel it in game which is fine Example

. If I run my Skyrim with all my mods minus DynDOLOD, it will run mostly fine. I say mostly fine because with how many mods I am running, I will occasionally get a stutter. I have come to accept that as I do understand that Skyrim and its engine is not perfect. These stutters are consistent enough to not bother me Example

. The problem with this is that I find Skyrims default LOD to be hideous and consider DynDOLOD to be essential and do not want to play with out it if I can absolutely avoid it.

I have tried to disable half my mods with DynDOLOD and then do the other half and then do groups of mods at a time and once I think I have narrowed it down to the mod that is causing the problem, it will just start right back up. One bright thing about doing this, is that I did discover that Enhanced Blood Textures will cause a repeatable stutter outside Riften every single time. Not sure why either, but I have removed that mod for now.

Another thing that I tried is that I copied my Skyrim and mods over to my wifes computer to rule out a computer issue. I received the exact same issue. Smooth and playble for a few minutes and then same stuttery mess. so I know its not my computer, and it should be something with my mods.

I have followed the STEP guide for SSE display tweaks and used the custom ini for Display tweaks and settings and followed the Step guide for Bethini settings and I am still pretty much have the exact same issue. Screenshot

Moved to the DynDOLOD 3 Alpha thread. Read the first post.

Post/upload logs and debug logs as explained on the first post.

DynDOLOD 3 is ALPHA. This is an ALPHA test.

It seems the setup might be overmodded and could be exhausting resources. The memory and RAM usage graphs at  https://imgur.com/rhWKbX6 hitting the top, seems odd.

Check draw calls with ENB.

Apologies for not including the log files. Here they are. I am unsure why MSI Afterburner shows that my VRAM is at the top like that. Skyrim Performance Monitor shows that I still have a long ways to go before my VRAM is maxed out. I will check the draw calls like you requested. When my FPS is uncapped I am well over 100fps except when looking at the open cities like Riverwood or Dawnstar and thats why I cap my fps at 60 rather than letting it run free.

Edit: I just ran through with the ENB window open and my draw calls were as low as 3k and only got close to 10k when passing through Riverwood. The rest of my test stayed around 5k - 6k draw calls.

You did not upload the DynDOLOD log and debug log.

It is odd that the memory has a flat max limit like this. You should investigate if the graph to show 0 to 100% usage or whatever else.

Check the papyrus log for stack dumps.

Check if there is any change deactivating dynamic LOD from the DynDOLOD MCM - it will enable again when crossing cell borders.

Test if there is a change if hiding all object LOD Level 32, 16, 8, 4 files respectively. Meshes\terrain\Tamriel\Object\Tamriel.X.*.*.bto where X is 32, 16, 8 or 4.

Sorry Sheson here are the other log files. I will check back once I have looked into the other queries. And I am sorry Sheson, I am not quite following, do you want me to hide all the files in this folder?

 

Edit: I enabled papyrus logging and I dont think there are any stack dumps? I am really not sure to be honest.. Here is the log. I also deactivated DynDOLOD from the MCM but I saw that it never enabled again when crossing cell borders? Either way I still had the same stuttering the the same places.

Those are the files at the path I mentioned. You might start hiding all BTO for the first test. If there is a difference, hide the files of one LOD level at at time to start narrowing it down. Then continue in a binary search.
LOD 4 will contain the grass and ultra tree LOD. So if there is a change there, generate LOD without one or both options to compare, though the billboard4 tree LOD should not really be a problem in itself.
If those files make a difference that can not be really pinpointed to a group/single file, shrink the texture atlas Textures\DynDOLOD\LOD\DynDOLOD_Tamriel.dds for a test.

Well this is a little disheartening. So as a blanket test just to check, I hid that folder in MO2. I was still getting the same stutter. I then disabled DynDOLOD completely to make sure it wasnt more of Skyrim's shenanigans and my test run was perfect minus for a stutter because I paused briefly. Results. The left side is me hiding the .BTOs and the right side is with DynDOLOD disabled completely. I will clean the plugins that contain disabled references as you requested and will edit the post

You are testing with a new game, right? coc whiterun from main menu console can be sufficient.

Checking the papyrus log shows no stack dumps, however (in addition to the appalling lack of mod authors not QAing their mods/scripts) you want to look at the hundreds of "cannot fetch variable named * of type int, returning 0." There might be something amiss with the animation setup.

If deactivating dynamic LOD and hiding object LOD does not change anything, then it narrows it down pretty much to records being copied/overwritten from other rmods maybe.

Test what happens if you hide the SKSE folder (ignore any error messages about not being able to find things). It is just to double check without dynamic LOD. If that does not change anything, see what happens without DynDOLOD.esp, only DynDOLOD.esm. If there is not change see what happens without any plugins. 

Depending on which plugin makes a difference, the next step would be to remove records from DynDOLOD.esp in a binary search.  Typically only worldspaces/cells/references but never references with the Editor ID Tamriel_Firstborn* or Tamriel_Minion*, as explained here https://stepmodifications.org/forum/topic/17510-dyndolod-300-alpha-103/page/314/#comment-260724. I would start with removing overwritten references in the persistent cell D74.

Alright we are getting somewhere now. So I still had the stutter with DynDOLOD.esm enabled, but removing it and only have the .esp and occlusion.esp enabled resulted in NO stutter. What are the next steps now since it looks like its the .esm thats causing the issue?

sheson typically must sleep, and I suspect that time is now where he lives.

In the meantime: Have you cleaned all of your plugins using xEditAutoClean as he instructed? Then you would want to rerun TexGen and DynDOLOD from scratch for Tamriel worldspace to test.

Also look at his last post link and reference to cell D74. You may want to sort this out before rerunning, but that's up to you.

Delete/move all DynDOLOD logs before regenerating TexGen and DynDOLOD. This will give you clean logs to share. And don't forget to disable all of the existing output mods for those before regenerating new object LOD.

I appreciate your reply and I understand that Sheson must sleep lol I was in no hurry for him to reply back I am very grateful for the help thus far.

Yes I have cleaned the plugins like he asked, but have not re-ran DynDOLOD, I will do that now.

I was not sure if looking at cell D74 still applied since it looks like it was for the .esp, but it looks like the .esm is the culprit. If re-running DynDOLOD does not fix my issue, then I will try to follow his suggestion as I am a little hesitant to mess around with that as I have not done this before. If you have any guides or suggestion to help that would be great (I read the post he linked several times, but its as clear as mud). This is what I see what I try and navigate to it. I am sorry I do not mean to be a dummy with this.

Again thank you for the help

The ESP relies on the ESM, so I wouldn't assume it's the latter. I would do as recommended in that post: remove records other than those with the Editor ID Tamriel_Firstborn* or Tamriel_Minion*.

This is the same method used when narrowing down a problem mod in your install: Disable top half > test. If problem persists, disable bottom half > test. One of those will almost always resolve the problem, so you focus on first or second half and repeat by disabling half of that (one quarter disabled), and so on until you isolate the problem.

Just save our your DynDOLOD.esp somewhere so you have the original. You are just deleting records and saving in xEdit and testing until the problem is resolved, and report back the record. Always use the same clean save to test.

Of course, there is always the chance that if you regenerate, the problem will be resolved (due to cleaning mods or some other action).

Since the DynDOLOD.esp has the DynDOLOD.esm as master it will typically no load without it.

If the problem happens only with the DynDOLOD.esm, then it is pretty straight forward now, as there are not that many records in the persistent cell D74 but mostly a single references (Tamriel_Worshopper*) in the temporary cells. Those are for dynamic LOD, so they do not really do anything with the DynDOLOD.esp.

So the binary search goes like this: Restore backup of plugin if problem goes away, continue removing "half" the records from plugin that has the problem until only a specific record remains. First remove all other worldspaces. Then remove the persistent cell D74 in the Tamriel worldspace. Then start removing half the blocks until you are down to a block, then same for sub-blocks, then same for the cells in the last remaining sub-block.
