You probably didn't do the manual install part properly. Try reinstalling following the steps from the guide: In the pop up for manual installation right click "Premade Weapons.of.the.New.Millenia" and select "Set data directory".Click the arrow next to "Optional Store" and highlight "Sound, meshes, textures" and drag them to "<data>".Uncheck "Optional Store, _OPTIONAL, fomod, images, Weapons.of.the.New.Millenia.Cheat.Cabinet.esp, and Weapons.of.the.New.Millenia.Honest.Hearts.Grunt.Patch.esp".Click [Okay].

Yeah, it's definitely not uncommon. And if you are using Project Nevada Extra Options - the Rebalance module there is known to cause gradual performance degradation.

Well, that's FNV... No matter how powerful your PC is the engine is old and ENB will hit the performance very hard. Personally, I've switched to Lucent ENB - it doesn't hit the performance that much and picture is nice (at least on my taste). But don't expect steady 60 fps if you are using ENB. Also I doubt that texture size in your case make any real difference. It's ENB's additional effects and old engine combination...

In my case goes down from 45-60 to 25-40 and that's bad. So I had to remove PN EO Rebalance esp and now I don't have any performance drops anymore. Can totally live without Extra Options Rebalance, especially, cause I'm playing with Jsawyer and Vicious Wasteland now. Also I don't think it's anyhow related to GPU because I've got GTX 970m and once the leak gets in effect even inside interiors avg FPS goes down to 30ish at times.

Will work means it will not crush the game but it doesn't mean that it won't cause the issues. A guy who is currently supporting PN Extra Options said he will look into it...

Oh, that explains. Thanks!

Avoid merging anything that has "errors" or at least verify afterwards in TES4EDIT that records did merge correctly by comparing them manually with orifginal esps. You have to read more carefully: -FCO esps and FCO masters. Technically they will work with my mod but it is strongly encouraged to disable all of them to get the best results and to get the correct version of this mod.

I don't know exactly the reason, but yeah... when some record is getting merged it may result in ILS. I fix such problems by trying to merge them in parts and see which exactly esp shouldn't be merged... Also I highly recommend checking mods for errors before merging. Don't merge anything that is reporting errors. I know that some "errors" are not exactly errors and will be merged fine, while others may fail to properly merge and you will end up with corrupted esp. P.S. Better to use new standalone merge tool. It's much easier and much safer. Check this guide (for Skyrim but part about merging applies to FNV just fine) https://wiki.step-project.com/User:Neovalen/Skyrim_Revisited_-_Legendary_Edition

Wrye Bash is doing great job when it comes to lighting mods like ILO. Just put proper tags and bashed patch will contain all the ILO edits making it compatible with everything without any need for additional compatibility patches. Mod order on the left side panel determines only file level conflicts - if different mods have the file with the same name and some location the one which belongs to the last mod in the list on left panel will be used. Right panel are esps/esms and their order determines record level priorities. If 2 different esps edit the same formid record then the one which is loaded last will be in effect.

Guide really needs to be updated. You cannot use FCO and NVR3 at the same time and it's pointless because they do the same thing anyways.

Nehrim when it's getting installed makes a copy of Oblivion files. So basically, I just copied everything from DATA folder of Nehrim as a mod for MO hence why Oblivion BSA's are displayed under the Nehrim mod. Removing them from the Nehrim mod folder was causing CTD right after pressing on New Game or trying to load existing game, even though, the same files exists under the original Oblivion\Data... So yeah... maybe it's also somehow related to strange AI invalidation problem that I had. And sure thing Oblivion is launched through the Steam. OBSE with plugins also works so here I think everything works correctly. MO + Steam Oblivion + OBSE hooking = pain in the a.. At least from my experience...

No, it's not installed to the DATA folder... Not sure why is it so obvious to you. The only non standard stuff in my Oblivion DATA folder is the OBSE subfolder with plugins subfolder. Everything else are just usual folders under the mods folder of MO - MO mods in other words. And yeah, MO seem to be really-REALLY buggy when Oblivion is under the Steam and MO have to use Script Extender hooking mode... For example, sometimes game is started with wrong Oblivion.ini - no the one from the MO profile. Sometimes if the mod was deselected in the left pane when game is launched mod is still there. Etc...

Then how do you explain that turning WryeBash's AI bsa makes it so AI doesn't work anymore? Yes, I am aware that first BSA in the list is supposed to do the invalidation but this is what I observe.

You mean the AI bsa generated by the MO? It is at the top, but still archives not getting invalidated not sure why. The AI generated by the Wrye Bash is at the bottom and it works now.

Just don't use both mods together. They are incompatible and author of NVR explicitly states it on his mod description page. They are doing the same thing so you don't need them both in any case.

So, I've managed to finally get Nehrim running through the Mod Organizer. One of the problems that I've managed to solve in a non-standard way is to use Wrye Bash to generate the Archive Invalidation bsa, because the MO's built-in Archive Invalidation didn't work for me at all for some reason.

Are you using PN Extra Options with Rebalance module? I believe that one is causing gradual performance degradation. Memory leak or some script that is causing high CPU usage - most likely...

It's definitely needed to have d3d9.dll inside the exes folder... At least if playing under Win 10. With latest MO

With ENB presets? Full HD+ ? ENB is just a massive fps killer. ENB preset is the reason. Also if you are using Project Nevada Extra Options - I think Rebalance module is causing a performance degradation over time.

Nice. Thanks. Do you use any big quest mods? Do you know how compatible they are going to be? I suppose there shouldn't be many conflicts, right? Probably karma is the only thing to worry about as JSawyer's mod does seem to change it heavily, right? I've tried to balance my game using PN. Like reducing loot, making bartering harder, reducing Exp from killing mobs to 75% and overall exp gain to 75% while increasing XP rewards for speech, lockpicking and hacking to emphasize questing and these activities and make it less important to rely on killing everything that moves... But still I do feel that JSawyer have done it much better with his mod, so was going to try it myself.

Does anyone use JSawyer together with PN Rebalance?

Are you using ENBoost?

Any idea why my Bashed Patch contains about 800 (!) ITMs? Is it safe to clear?

There are many other possible reasons for game to crush beside memory usage...

Here's what Boris was saying on this matter: https://forums.nexusmods.com/index.php?/topic/1042116-ctd-and-performance-patch-enboost/page-9&do=findComment&comment=8509999 In most cases ReduceSystemMemoryUsage=true increase stuttering, but for AMD users. I'm personally on nVidia and do not notice any stuttering with ENBoost on... But maybe it also depends on some other factors, like for example the amount of big textures? I've optimized all my textures with ddsopt and they are unpacked from BSA. I'm also following guide didn't install more then 2k textures...
