Tips do Reduce LAG

16 01 2008

Hello Residents!

 Some of us really face this so called LAG. This really annoys when you are in some party, with full of people, and you want to be on the topics but you can’t because your avatar walks, see, interact and speak so slow with others, that makes you mad.

 What is LAG ?

-A lag is a symptom where result of an action appears later than expected. (See Wikipedia for more information.)

How to face LAG ?

There are few options that you can config at your application, to help you reduce lagging and make your avatar works faster.

First, you go at Preferences on the Login menu or the Gray menu while you are in-world. Then click at Network tab inside preferences, then reduce the internet connection to 350 Kbps, and cache to 300 MB.

Then you click on Graphics tab and change your Draw Distance to 64. Now at Advanced Graphics, reduce your Particle Count to less than 1500. And uncheck the Anisotropic Filtering .
It is recommended if you use a lower PC processor, to dettach all your scripted objects and HUD (Head-Up Display). I know that most of you uses most of time your AO huds or anything else, but if you want to stay on a full sim, with less lagging problem. it’s up to you.

Frequently Asked Questions:

Why reducing my Internet connection will reduce the LAG? It’s not the opposite, it means, to raise the connection?
No, it’s because Second Life uses ALL your internet connection avaliable. You have to administrate well how you use your connection to not have troubles accessing websites and etc, while you are in-world.
What about the Cache, what does it do ?
Cache is a place in your HD wich saves all your Second Life information.  More space you use to cache, more slower Second Life will be.

What is a Draw Distance?
It’s the avaliable space from enviroment that your avatar will handle to see. More higher your space, more details will be downloaded to your cache (texture, objetcs), making your pc slower and Second Life as well.

What is a Particle Count?
Is how the particles will be counted to your avatar.  Many particles, more slower it will be.

Actually, you’re wrong. Reducing your cache size will mean that more information is being downloaded directly from Second Life’s severs instead of being loaded from your hard drive, which is drastically faster. Also download strain on the server affects everyone on that sever. So by limiting your cache you’re not only causing more lag for yourself, you’re causing more lag for everyone else. If anything Linden Labs should increase the maximum cache size beyond what it currently is. Which is 1 gigabyte. Singularity viewer allows you to set your cache to about 10 GB allowing more space for information to be loaded directly from your hard drive instead of being downloaded directly from the server.

You are however right about everything else. Lowering your bandwidth below 500 kilobits per second is highly recommended. I use 1000 kbps often, but that’s only because I do combat in SL, and I need things like bullets to rez quickly. You should never increase your bandwidth above 1500 kbps. If you do you’ll lag the sim.

I have a decent gaming computer so I generally don’t have to worry about these things, but there are also a couple of tricks you haven’t mentioned here that I’ll kindly post for anyone who’s interested. Which is likely quite a lot of people judging on how often I hear people complain about lag in SL.

To improve viewer performance; in Preference; Graphics; Hardware Options

-If you’re on an old computer; 5 years old or more; disable OpenGL Vertex Buffer Objects. If you’re computer is fairly modern leave it enabled, it’ll give you a performance boost.

-If you use an ATI/AMD graphics card; disable Streamed VBOs, and OpenGL Frame Buffer Objects. If you use an Nvidea graphics card leaving these options enabled may improve performance.

I have a mid range gaming computer. I run with maximum settings, except shadows (it’s very broken, and 9 times out of 10 it crashes my client.) I usually have my draw distance set to 512 meters, except on the mainland where I lower it to 96 meters. I get at peak 160 frames per second. Frankly if your computer can’t manage even 30 fps with all the performance tweaks, minimum settings, and low draw distance, you should upgrade your current computer, or buy a new computer.

Finally there’s script count. Having a low script count on your avatar generally means you’re not taking up excessive amounts of script time, or hogging sim memory. This is not always the case, since it’s possible for a single script to crash a sim, however lowering your script count does decrease the ammount of sim memory you use, and reduces the chance of wearing (a) laggy script(s). Scripted attachments such as hair, shoes, jewelry, HUDs, AOs, and clothing attachments like sleeves increase your script count. Most common 3rd party viewers have a script counter built in allowing you to right click on an object, or avatar (including your own), and see exactly how many scripts they have.

*Beware some viewer script counters only count attachments worn on the avatar, they don’t count scripts in HUDs.

I have 12 scripts on my furry (modified Kinzart Leopard) combat avatar. That’s including my assault rifle, combat HUD, and AO. I have seen people with over 1000 scripts on their avatar, wearing nothing but hair, and boots. The main culprit behind high script counts is resize, and recolor scripts in hair, and clothing attachments, with at least one script in each prim. When you consider how many hairs have over 200 prims, you can see how quickly your script count can add up if you don’t delete these; for the most part; useless scripts. I usually recommend people who have high script count items to make a copy of the item; select the item; then go to Tools > Remove Scripts in Selection. This is recommended for things like hair, and clothing attachments which you have already resized/recolored to fit your avatar. Personally I prefer using the build menu to edit items, but some people can’t seem to wrap their heads around it. So for many; resize, and recolor scripts can be useful, but when you’re done modifying the item to your taste, delete the now useless scripts. Also a word of advice to content creators. It’s possible to control the properties of all the objects in a linked set with a single script by using the object names, or object descriptions. So a 256 prim hair doesn’t need 256 resize scripts, it could just have one script that’ll do the same thing.

*Beware of products that are no mod, and have high script counts, you will not be able to delete the scripts in them.

Many sims are adopting enforced script limits, usually between 30, and 100 scripts, and 2000-3000 MB of script memory. If your script count is over the limit you will either be asked, and/or forced to leave via sim admins, and/or scripted objects. Some places will even outright ban you for having too high a script count. So if you have a high script count, it’s a very good idea to lower it.

If you have any questions feel free to IM me in world, if I’m offline please send a notecard instead.
