Which is better in what ways?

They can be found here at TesNexus - Your one way ticket to every mod you could ever need and if it isn't there chances are someone is in the process of making one!

Streamline. - http://www.tesnexus.com/downloads/file.php?id=10400


I know they aren't compatable because that would solve FPS problems for everyone
But Streamline seems more complicated; FPS reducer, optimises meshes and does something with RAM etc. And still in beta stages I think.

While Operation Optimisation jsut replaces the meshes with less FPS hungry ones, although there's no cosmetic difference in game there is a visual difference, that beign you have a better FPS xD Also I recognise that it's by Quarn one of the amazing developers that helped with pretty much all the Unofficial Patches.

So what are your opinions guys? And girls?

Operation Optimisation (I may be wrong on this so don't quote me) is out of date and really will more than likely do more harm than good.
on a different note, watch out for how many threads you post this isn't considered spamming, especially since it is unrelated to the other topic, just would like to let you know. But don't worry, as I said you have a legit reason to have a second thread up as it is unrelated to the other thread.

edit:
thanks for the links.
If you check dated uploaded/date last edited, it shows you how extremely out of date Operation Optimisation is.

They do completely different things so the question is meaningless.
And yes, they are compatible.
I think OO (or was it Polygon Overhaul) contains some faulty Rock mesh(es), though.

So Go with Streamline? Just a bit curious about it being in the beta stages and being a bit buggy :/ But if it gets me a better FPS, Hell; I'll take it !

I definately recommend Streamline. I do not use it, but between the two, I can say Streamline has more promising results, since OO is out of date.

Streamline is not buggy, but it's important that you read the instructions carefully to get the best results.

I think Polygone Overhaul had the faulty meshes. Operation Optimization was good, but limited and didn't work for all systems equally. Nowadays it is probably better to use PyFFI. A thread can be found http://www.gamesas.com/?showtopic=1064823. Requires a bit of work though.

Regarding streamline (only talking about the streamsmooth feature here) I suggest you think about your specs and mod setup before you use it. Oblivion eats a lot of CPU power by default already, but not so much GPU power unless you overload it with insane settings and hardcoe graphic mods. Streamline basically trades CPU power for GPU power since it has some large scripts that run every or almost every frame. You have to find out what the limiting factor is in your system for Oblivion. When I had a system that was worse than what I have now I tried Streamline. At first I was happy with it, but then I came to a cave with lots of NPCs inside. Even though Streamline set my graphic settings to lowest possible I still only got ~20 FPS. I was a bit frustrated and just for testing I turned SL off. Suddenly I got 25+ FPS in the same cave! Back then my CPU was the limiting factor (in other areas as well) so I went without Streamline.

EDIT: You should also give http://www.tesnexus.com/downloads/file.php?id=23208 a try.

And if your framerate is still problematic http://www.tesnexus.com/downloads/file.php?id=5434 can help a lot as well in exteriors (if you have grass turned on).

Operation Optimization is outdated and not recommended. I heartily recommend a combination of Streamline and Oblivion Stutter Remover. Read the readmes for the best effect. And of course check out http://sites.google.com/site/oblivionpoinfo/optimization/optimizationmods

Operation Optimization was obsoleted by PyFFI. Using it would be of very limited value.

Polygone Overhaul is the one with the bad rock meshes, and other bad meshes too.

You have the wrong idea as to what Streamline does. For one thing it has nothing to do with optimising meshes. And it's not really an FPS reducer, but an FPS optimizer. It adjusts your graphics settings on the fly so that if you get into an area that is more demanding than others, it will reduce things like shadows or grass distance etc. in order to give you a few more FPS. Once you get into an area where the demand isn't as high, it will turn those settings back up again. It's really not that different than you opening up your Options and lowering some of your display sliders, it just does it for you automatically. Plus it adjusts certain settings that aren't covered by your graphics sliders. As for the RAM, it will occasionally purge your cell buffers, getting rid of data that's not longer being used by the game to free up space. And no, it's not in beta anymore. There's been no development on it for quite some time now, the author just hasn't been around to change the name of it. It's very stable the way it is though.

Streamline's interior streamsight fog and clipping distances are related to the exterior values. This can cause larger interiors spaces to be rendered than would be with vanilla values. So you can have more actors and scenery being processed than necessary, leading to FPS loss rather than gain. I think Arthmoor had a possible script edit to prevent this, in the forums.

If a fix exists, that would be nice to know. My FPS in interiors is almost always maxed out, so I would not really notice nor suspect SL to be doing anything "funny."


Edit: I still recommend using it and setting it up properly. It would be nice if Arthmoor confirmed this as well. Streamline has an exceptional record in my book.

For me it was never a FPS issue, but a visual one. http://www.gamesas.com/index.php?/topic/1073686-concern-with-streamline-v-31-open-beta/page__p__15613550&#entry15613550 is Arthmoor's fix.

Thanks, I will ask for his permission to put this up on TESIV:POSItive. I already have a couple of pages in mind that can use it. If you had a screen shot of the issue to go along with it, I could probably use that as well, only if the visual aspect of the issue is noticeable of course.

I have Streamline, Oblivion Stutter Remover and weOCPS (though i hear that last one should be ditched?). With proper settings they indeed do wonders to framerates. I have Operation Optimization omod too, install it first and let everything overwrite if needed. I would use PyFFI, but i haven't figured out how to extract and repack bsa archives yet.

OBMM can do both: Utilities > BSA browser/BSA creator

Thanks. Time to give my processor a workout

didn't streamsight have an issue with Let There Be Darkness in interiors?

Just quoting this to say that this mod is a gift from God.


XD

I use them both. I have not heard of this. Also, I am one of the users who thinks that WeOCPs should only be used as a last resort. Work on making your setup stable before adding it. If it does not help, drop it. If your game is crashing after 3+ hours, the crash is likely memory related, and WeOCPs cannot help with that.
