Question about mods and lag

[PhoenixBlue]

Hi I have a quick question.

So if I download and installed a lot of mods manually (I put all the files in the folders myself) and it makes the game lag kind of, and I want to remove the mod to increase fps, will unchecking the mod in on the startup completely disable it so the game performance increases or do I have to actually remove all the mod's files from the folders?

It will completely disable the script, so yes.

 

However if you overwrote any models or textures then the models and textures will stay the same.

Unless you've installed mods that replace/alter vanilla content, yes, it should completely disable it. See, if you've downloaded something like a high-res texture replacer that uses the same path as the original texture, it won't matter if there's a plugin to disable cuz the game will read the high-res texture anyway, and your lag will continue.

 

That's why you should learn to use some kinda mod manager though, won't run into trouble with replaced files and stuff.

 

EDIT: Damnit Marharth was quicker ;)

Meh, you were more detailed anyways :D

The reason for decreased performance may have more to do with your antivirus than the mods themselves. Sure, there are plenty of mods that will drag FPS down but i used to notice loss even with mods that were designed to boost FPS. Adding the Oblivion exe to the AV's list of trusted applications fixed all that. I now run around 100 esps, including a few major performnce killers... and actually have improved FPS over vanilla.

 

Make sure to include all game-related exe files in your exclusions also. Think OBMM, Wyre, OBSE, Cosmic Sky Cycling, etc.

 

If you use Game Booster or similar programs to shut down background processes, this needs to be included also. I have tested Game Booster in this regard, and without it being included in trusted apps, i get a 10-15% drop in overall FPS. Exclude it, and it gives me a 5-10% gain.

 

The quick explanition for this lies in the way AV programs handle archived files vs. non-archived files. An archive will be scanned once per session, while non-archived files will be scanned everytime they are accessed. Vanilla resources are archives, mods aren't.

 

I once tried gaining performance by unpacking all the bsa files and repacking them with no compression, but it really dragged my FPS down since they were no longer archives. Now that i know a little more i think i'll try it again.

 

I use Kaspersky antivirus. I used to just include the Kaspersky exe in the processes i wanted either Game booster or Advanced System Care to shut down, and for a long time i thought that worked. I was wrong. After going through the detailed reports from my AV, i noticed that everytime another program tried to shut down Kaspersky, it got denied. Any AV worth using probably does the same.

 

A thank you to MarkinMKUK for getting me thinking about this.
