From: FlipperPA Peregrine ... - many textures in the W.A., including the flowers, were uploaded as 1024x1024 32-bit targa images! Sorry, but for the flowers, 128x128 would have been MORE than enough.
- just about all the textures - including the solid ones - were uploaded as 32-bit targa images. 32-bit targa images should only be uploaded if an alpha channel (transparency) is necessary. Even the solid walkways were uploaded as 32-bit targa... Woah. If this is true, I find it startlingly dumb. Even I know not to do that kind of thing and I have known it since I was six months! They also had to redo the WA a couple of times since it was first put out and no-one noticed that?

From: FlipperPA Peregrine A few comments: So, at the default setting, this does nothing but improve efficiency... that's A VERY GOOD THING. Over 95% of the people in SL don't tweak their settings, so to me, this is pretty much a non-issue. If my personal avian overlord Psyra says he doesn't see it being an issue - then I'm okay with it!  The creation of alt accounts within SL won't even chart on the total number. I'm guessing less than one in one hundred people create alt accounts - just the super-duper die hard types like us do! Let's not forget, most people are fairly casual users, not the 80 hours per week type addicts most of us on these forums are.  Eggy created 100 alt accounts and culled attachments in beta. LL is also improving the efficiency and frame-rate at the Welcome Area (finally!). After many weeks of pointing out how beautiful but badly created the Welcome Area is, changes are being made. To wit: - many textures in the W.A., including the flowers, were uploaded as 1024x1024 32-bit targa images! Sorry, but for the flowers, 128x128 would have been MORE than enough. - just about all the textures - including the solid ones - were uploaded as 32-bit targa images. 32-bit targa images should only be uploaded if an alpha channel (transparency) is necessary. Even the solid walkways were uploaded as 32-bit targa, which causes the Second Life application on your computer to do the "math" associated with transparency (figuring out what's being it, what order they should be displayed in, etc)... this causes a lot of math to be done on the client, causing framerates to drop significantly, even when the texture isn't truly transparent. Whoever created the new W.A. sure has an eye for artistic beauty, but needs a big lesson in efficient building! For the first impression of Second Life, framerate needs to be addressed, and I'm glad to see the Lindens starting to do that both with attachment culling and improving building efficiencies at the first place everyone sees! Regards, -Flip Excellent Info Flip. I think it would be in the interest of the SL world; if this information was in the form of a notecard in noobs inventory when they arrive in SL.

Cat hehehe, thanks. Yeah, its not exactly "common sense" info, but it is something you learn pretty quickly: use textures as small as you can and you'll decrease lag a lot.  I'd like to hear a Linden weigh in on the 32-bit targa issue; I don't know of a way to automatically discard the alpha channel if its not necessary in the conversion process to JPEG2000, and I'm not sure if its possible. All the proof you need? Go to the welcome area, and turn on highlight transparent - the entire screen goes red!  Does anyone know how to check textures sizes in the new version? You used to be able to, in debug mode, edit an object and then hit control+shift+3 and the textures would be highlighted in yellow that were in the object that was selected. When the "loading bar" indicated the texture had completed loading, you could see its size (that's how I found out about the W.A. problem). This doesn't seem to be the case any more and I'm wondering why! It was an excellent diagnostic tool to reducing lag. Another cool option? How about a place where we can see every texture we've ever uploaded with an option to have SL resize them, and have that re-size occur grid-wide. When I first started, I used several large ones that I'd like to replace. Regards, -Flip

From: Reitsuki Kojima I'd always assumed since everything gets converted to JPEG2000, it didn't matter the format you uploaded in. Yeh, it does. I've used my l33t sk1lls (well, the fact that I have a copy of Photoshop) to download and re-upload some of the freebie wood textures that are going around as 24- instead of 32-bit. It completely solved the problems I'd been having with texture-jittering in organic builds.

From: Kilmarac Drago You don't have a god given right to tell anyone they cant have attachments, and if you dont like it, then either dont come to the large event, turn your LOD down, tweak your settings, or (god forbid) go out and get a better graphics card/computer.
Who are you to impose upon everyone else what we can or cannot put on our AV's? The LOD change does not prevent you from putting on any kind of attachment, big or small. All it does is allow people to choose if *they* see it or not. The rights to your avatar ends at the tip of your nose - or your tail if you're wearing a furry avatar. It does not extend to forcing it to be displayed on others' screens. If you dont like it, set your LOD to high and enjoy. Personally I'll be keeping it set low so I can enjoy the framerate. - Newfie

Cristiano, this is such spin! From: Cristiano Midnight t wasn't just "I am concerned about this..." it was "OMG THIS IS A VIOLATION OF FREEDOM OF EXPRESSION", and had the usual "THE SKY IS FALLING OMG THE END IS NIGH WHAT ABOUT THE CHILDREN OMGLOLBBQ" feel to it There were other posts about this, and no one from Linden Lab (nor you) seemed to take notice when it was just "Hey, I dunno if this is wise ... " We were talking legitimate concerns, and very thankfully, those concerns did not surface - but once again - we found that out only after Linden Lab had opened up a preview, which should have been available in the first place. What if culling did cut items more? Would it then be me saying "I told you so?" The possibilities were there and are still there - as I showed with my screenshots there are still some issues with culling, even at 50% on the slider. From: someone since Hiro had not seen the actual implementation and was just wildly speculating. If you bothered to read the original post - The only thing I asctually asked for was nothing more than LL communicate with the SL community before implementing this patch, so that it could be examined. And Cristiano, that just because a person does not see an implementation does not mean that they can't imagine the kinds of cases that may break it. From: someone It's all about the approach, honestly - if you fly off the deep end about a topic right out the gate (especially uninformed), it will most likely be met with equally over the top responses. Translation: "It's okay that me and Enabran attacked Hiro because our personal opinion was that he was over the top." KETTLE. POT. This is so hypocritical it isn't even funny. From: someone Forum nature, I suppose. This thread overall has been more calm because of Hiro's approach, combined with the fact that this time around he actually did the research and was not just speculating. The other thread was calm too except for you and Enabran. Other people managed to state their opinions without ridiculing specific people. That includes me - because while I may overreact about concerns of freedom of expression, your overreaction was about a post in a forum. Tell me, whose is a more worth cause to overreact to? From: someone I still don't find the results with the slider turned all the way down to be shocking or cause for any alarm at all This is so far the only positive contribution so far that you have made to this thread. Why didn't you just post this and let it be? Why do you have to beat in your point, especially after I've apologized for overreacting? From: someone I am sure they will continue to tweak the culling Why are you so sure? Many patches are implemented and have bugs that are not fixed for months. From: someone but I am glad to see them making some efforts to allow more adaptive performance I agree as well. And I want to see the efforts be successful and not infringe on expression. From: someone - especially since LL has to deal with users adding more and more prims to their avatars - a problem that did not exist to this degree until the past year, Oh, that's crap. There's been furries and hoochie hair for longer than that. And I may add, you complaining about things "in the last year" really come off as someone who's pissed that it isn't the "good ole" community of 500 active users. From: someone I am also glad they responded to requests for a preview, and interesting, it was a preview on the live grid, which was unusual. Expressing concerns about something is not a problem - ranting and raving uninformed and predicting doom and gloom is something else entirely. My "ranting" was a pretty crappy rant if it was one, and it's you and Enabran who have been carrying on the histrionics since this started. I have calmed down since my first post, but you two fight with the urgent sense of forum Kingship as if your very reputation stakes on making sure everyone in the world knows I overreacted some. I overreacted? BIG WHOOP! It's over. Let it go. Take some prozac and go to another thread. You've not expressed a single new thought since your first one.

From: Eggy Lippmann It doesn't need tweaking. If I manually set detail to minimum then it's a fair bet I need it set to minimum. You don't have a god given right to put shit on my screen and drop my FPS. If you think you do then I'll just ctrl alt shift 1, 2, and 4 like I so often have to do at large events  Look, here's the overall problem - you have a laggy system called SL. Everyone knows it, LL has acknowledged it, and they're looking at ways to make it work better. Now, in the process of making it work better, we want to make sure solutions don't break the system, or restrict peoples' ability to restrict themselves. As I stated time and time again in the other thread, I don't think people have the right to "put shit on your screen", but the censoring that should occur should be one that affects the avatar in a fairly predictable way, and does not lop off prim-heads or wings or such.

Hiro,
I'm not going to respond to you sentence by sentence because, well, that is rather anal. I was not addressing this thread, I was addressing Martin's question about people's reactions. Your claim that it was only Enabran and I who found your original thread absurd is completely false - spend a little time rereading that thread - you overlooked about 10 other people who said the same thing. I know it's easier to claim it was just Enabran and I, but before talking about rewriting history, at least be aware of what you are talking about.
My point about the attachment issue in the past year is valid. Yes, we have had prim hair for longer than that - but the use of highly detailed prims for everything on hair, shoes, jewelry, gigantic avatars, etc.. has really flourished in the past year - it has been part of the evolution of SL. When you have people who have more prims on their avatar than your average build, it adds stress to the system. Combined with the fact that prim attachments being the absolute norm now - everyone has prim hair and prim shoes and generally all kinds of other things attached to their avatars in ways that we didn't use to, this is one of the contributing factors to scalability problems.
Whether it was 1 year or 1.5 years, it has been a recent occurance - in the first year of SL, prim hair and shoes were not that common. Yes, we had furry avatars, but even those have become much more elaborate over time - it has just been the natural evolution of things. Making a point out of how long it has been is just silly - the point was it is a real stress on the system now, combined with the steady rise in population.
Telling me to take a prozac is a cheap shot, Hiro. I'll just leave that one alone. So much for positive contributions.

From: someone Your claim that it was only Enabran and I who found your original thread absurd is completely false Indeed, it is false, because that's putting words in my mouth. I've said you're the only two people who have been consistantly drama in this thread. Other people were able to express their opinions and move on. Now, please, unless you have a new thought to add, please do the same.
