Alright, so. I had to trim down a lot of stuff that the guide uses because when I finished the guide I had around 197 active plugins and FO3 did *not* like that. After 5 minutes of moving around in the wasteland, I had missing meshes, missing textures (white bodies) and menus refused to load. I was able to fix this by slimming down to around 165 plugins but it still happens occasionally if I get into serious combat scenarios, along with an extreme and unbearable amount of stuttering and freezing that makes heavy combat completely unplayable. This I haven't been able to fix.
I'm also having recurring crashes and buggy npc's in the areas of the Temple of the Union (hannibal dosen't spawn, when he is forced to spawned he just walks away into the wastes), Rockbreaker's Last Gas (an enclave patrol with unkillable/undeletable members keeps crashing my game, fixed by using killall) and Evergreen Mills (crashing AND unkillable Fallen Brothers). The last one is a big problem, particularly the northern shack, where if I enter it with AI on, it is an instant crash. However, if I turn off AI with tcai and tai, it is fine. If I then turn it back on, crash. This one I haven't been able to fix. I even tried lowering MMM spawns and waiting 4 days for cells to refresh and respawn. 
Anyone have any ideas? When the game works, I'm having a ton of fun but it seems to be not working more often then not. 
I'm running Windows 10 with a 4gb 970 with the latest drivers, 8gb of ram and a i5-4670k. I have all the suggested INI tweaks in the guide active, along with ENBoost. I also have all my drivers and runtimes (directx, c++, NET, etc) up to date. I'm running out of ideas.

Did you try running the game with one or more MO profile(s) that have fewer plugins to see if there might be one or two plugins causing a problem? I've run FO3 in the past with a lot of plugins, by the way, so I don't think it's just the number of plugins. I've used the game with all the mods in the guide except for some marked optional, and I haven't tested all the quest mods in the Potential quests section (as mentioned in the guide). For example, I did a short test of 3DNPC Fallout Bundle but I haven't run it for a long period yet, and it's still an alpha version.

When I was starting the modding, I would test it in sections (much like how the guide is laid out) and found no problems until I was finished and went out into the wastes and had the engine problems. I should also mention, the modding was started on a previously mod free save with just the DLC. And to make matters worse, I did a huge no-no because I kept removing mods from my load order and continuing on with saves, so I probably have a lot of script crud in my saves that I don't know how to fix. I haven't tried my load out on a completely fresh save because.....to be honest, I want to continue with this character.

Things seem to have settled down with the mods and while I still have the issues every now and then, doing a killall in problematic cells seems to work ok as a kludgey solution. However, now I'm getting missing mesh errors with 20th CW weapons, specifically the Ruger Mk. II Silenced. It works fine when I drop it into the world, but when it's equipped I get the missing mesh error in both first and third person. I had this before but toggling AI on and off fixed it. This time, however, it seems that isn't cutting it. I tried reinstalling the resources for the mod but that didn't help either. Any ideas?


Also, are there issues running the GECK through MO? It keeps instantly crashing when I start it up.

I've been able to run the Geck through MO with Fallout NV, although I haven't tried doing this for FO3 I expect the concerns are the same. Take a look at the recent STEP forum post on using the CK through MO for Skyrim. There are some similar steps needed when doing this with FO3.

Alright, hopefully it isn't just me because I feel like I did everything right, heh. Also, I managed to get the GECK working by unloading all the plugins and reloading them one by one, there might be a mod that is not behaving well in there.


Also also, the link for the Collision Meshes FO3 Pack re-directs to a 404 page on mediafire.

I looked at the mesh from the original 20th century weapon mod in Nifskope and I didn't anything that was obviously wrong - note that I'm not a graphic artist and I don't spend much time using Nifskope. I don't see how the patch mod causes the problem unless the RH_Ironsights version of the mesh is bad. The plugin does change the projectile models to use xCalibr versions, but these should be OK.


This what makes it fun to mod Bethesda games  :ermm: .
