This is the only way to properly fix this. OP, do this if you want to fix it.

It's probably caused by ambient lighting, i.e. artificial lighting in almost every room in Oblivion. However, since it's caused by an uninstalled mod it might be hard to remove.

Crashes on startup are often related to missing masters. You already did a lot of research which is good. Your problem looks like the game fails to load Oblivion.esm as soon as any other esm file is present. You can explicitly enable Oblivion.esm in Oblivion launcher -> Data files. Although that file should be loaded automatically, it might be some kind of weird bug you're encountering. Another problem are file downloads through IE. Sometimes these file are marked as "unsafe" and after extracting them, the Oblivion process may not have read access to these files.

First sort your load order. If that doesn't work, disable a bunch of mods and try again. Disable/enable more until it works.

Might very well be one of the mods or a combination of mods. Make sure to install the SKSE memory patch, this might solve your problems!

Did some more testing, also with SSME (should be the same as SKSE memory patch though) and I think it's impossible to set uGrids at 11 and speedrun for over 30 minutes. No videos or actual proof can be found.

Trying to increase stability I've been reading the forums and see some people mentioning how they can run around the map in a (heavily) modded game, basically Vurts' stress test, using these settings: - Fresh Windows + Nvidia drivers + Skyrim install - ENBoost, memory patch, etc. - uGrids 7 - player.setav speedmult 1500 - set timescale to 1500 - tcl Now, I can reproduce this (4.4Ghz CPU, 16GB RAM, 4GB VRAM, SSD) and run around for 30 seconds up to 10 minutes but not longer. However, people claim they can run around as long as they want, for over 30 minutes, and even with uGrids 11. I cannot reproduce this at all, maybe someone can verify if this is actually possible?

Good luck in your future endeavours! And thanks for all the mods, although I don't use them myself I like to read your descriptions and posts.

The Papyrus log does not help with crashes. Do you have the SKSE memory fix enabled? This helps to prevent a lot of random CTDs

Copyright on music is pretty long and also depending on your location. I'm pretty sure OOT music is still protected in most countries. What you can do is describe how to add the music to Oblivion yourself, in the form of a tutorial. So you won't be releasing a mod with copyright protected music but it's completely legal to explain other users how to do it themeselves.

Two things: 1. The unofficial mod might not work if you install it during a playthrough 2. More importantly, the racks only work for me if I have the new weapon equipped in my right hand.

Over-abundance of script-using mods and script heavy stuff: that's exactly what I think when looking at your graph. Your VRAM usage is way under your max. I'm using a similar processor but with a 2GB videocard with an ENB and some graphics mods and there is very little stutter in my game. Although your mods will probably work fine individually there can be massive script lag when combining them. I had some serious stutter while running enhanced blood, frostfall and a bird mod combined. While each mod worked fine on it's own (except the bird mod) combining a bunch of them creates papyrus (the scripting engine) overload.

Probably fixed by the unofficial skyrim patch

You enblocal has a VideoMemorySizeMb of over 10GB and a ReservedMemorySizeMb of 2GB. Both are way too high. The problem is, these variables are hardly documented by the ENB author and lots of ENB mod authors advice you to put these number at very high values. For your system with a 4GB card try setting ReservedMemorySizeMb to 128MB, 256MB or 512MB. Also set the VideoMemorySizeMb to 4GB.

You may have encountered a know bug. The unofficial patch maybe fixes this, check this page for more info: http://www.uesp.net/wiki/Skyrim:The_Straw_that_Broke#Bugs
