Cool VL Viewer forum

I started this topic so people can say how this branch works for them.

I just tested it for a bit and i`m not to happy with the 3.3 renderer. Max fps now with all on low is 20 and with the old renderer it was 60-70.
Also the first version before the 3.3 renderer used to crash a lot for no reason.

This is just the feedback that you asked for.
Please keep v1.26.4 maintained because not all of us have new CPU & GPU.

If you get crashes, please open a topic in the Bug reports forum, following that forum's rules and providing all relevant logs and repro steps.
Please also note that v1.26.4.23 will actually include all the changes that went into v1.26.5.0 because I need to switch to the new build systems used by LL (i.e. glibc 2.7 or later and VS2010) so to have a chance to be able to keep maintaining v1.26.4 in the future. So, if you crash with v1.26.5.0, better telling and properly reporting the bugs so that I can fix them !

Here is my experience with v1.26.5.1 on Windows 7 64-bit:

At first I had problems enabling deferred rendering. Took me a while to find out that I not only needed to enable the checkbox for it on the graphics tab, but also needed to move the slider to Ultra first. After I found that out, it worked fine.

I wanted to compare FPS with v1.26.4.22, but I had also just updated to the latest Nvidia driver (from 285.62 to 301.42), and now v1.26.4.22 will only give me about 1 (!) FPS with deferred rendering. I *think* deferred rendering seems to work more smoothly now. I think I was getting about 15 FPS with v1.26.4.22 before updating the driver, while I now get 25-30 FPS with v1.26.5.1. This is with an Nvidia 580 on a 30" monitor and the viewer running in a window with about 2440x1500 pixel.

I also got a crash of v1.26.5.1 at one point, but I forgot to keep the logfile. If it happens again I promise to remember to keep and post the logfile.

What kind of troubles did you have, exactly ?... As long as the Atmospheric shaders (and all lower shaders, i.e. "Bump, Mapping & Shiny" and "Basic shaders") are not enabled, the "Deferred rendering" checkbox stays grey (which is normal and simply indicates you need to enable the proper shaders first); as soon as all shaders are enabled, you just have to check the "Deferred Rendering" box and "Apply" the graphics settings.

Wow !... It looks like the new drivers are pretty f*cked up then... Strange, because here, under Linux and with 304.22 (beta driver) I get the best frame rates I ever had with my GTX460 (in non-deferred mode, my best case scenario FPS rate even jumped from 130 to 170fps with v1.26.4).

Impressive figure for such high a resolution... What about non-deferred mode ?

Yes, please, do report crashes !

The problem was that by checking deferred-rendering and clicking Apply very little happened. There was a short drop in framerate, but that went back to normal almost instantly. I did notice some difference in the rendering though. Invisiprims stopped working and the anti-aliasing looked slightly different. But there were no shadows. None. Once I moved the slider to Ultra the shadows were immediately there.



The slowdown is now happening in v1.26.5.1 too. GPU-Z shows that the driver has set the core-clock of the graphics-card to very low and won't speed up again. Time to install a different driver. And then check again...



It was about 80-85 fps at the same place.

I will try again later and post updated figures once I have a working graphics driver again.

Ok. The driver was causing the slowdown in v1.26.5.1 that I saw later on. The clock-rate of the GPU was fixed at a very low setting. 50MHz instead of the normal 772MHz. I'm using driver version 304.79 Beta now. Both v1.26.4.22 and v1.26.5.1 work fine with that one.

The low framerate with deferred rendering in v1.26.4.22 was not caused by the driver, but by some borked debug settings that I had changed. With the new driver, clean install and deleted settings-file it is now back to normal.

v1.26.4.22:
Non-deferred 120fps
Deferred 45 fps (only 4.9 (!) before the clean install)

v1.26.5.1:
Non-deferred 95fps
Deferred 48fps

So the new renderer is noticeably slower with non-deferred rendering, but slightly faster with deferred rendering.

I just wish it would be easier to find a good-working Nvidia driver...

Yes, this confirms my own experience, the question being: "is the deferred render speed gain worth the non-deferred render speed loss ?"... At 120+ fps, it's not much of an issue, but more testing needs to be done in heavy environments (with loads of avatars and complex objects) and then see how v3.3 fares when compared to v2.6, both being in non-deferred render mode...

I will help you with the low end side of things... i`l keep testing it and i will post here the debug for every crash i have. Also... can u make a buton with "copy log to clipboard" or "open log file"? Or some kind of way that will make posting logs easy.

btw i noticed something strange on the v1.26.4 version (and i think it dose it on the new one also) , when i login its full power fps like avrage 30 but after some time of use like 2-3 hours it gets slow and frames drop to like 10 or even in a 8h scenario it droped to 5fps. I hang out in info hubs with lots of people around so i keep my avatar impostors to 1 and also basic shaders are disabled. Is it a problem with the GPU memory that gets full and stays like that? I`l just post a log from just a short login and tp`s from sim to sim so you can see what i get and also the drop in frames.

Well, I've got my usual crash when the viewer tries to load shaders on an Intel card. I don't expect you can do much about it, because Intel isn't supported on Linux, which (is I suppose) why no viewer3 works on my system, but for sake of completeness I am filing the report.

EDIT: Ah, by the way, at least on my system, the viewer takes a few moments to start. That is, the main window opens instantanously, but it takes some minutes to draw. It's not important, just a little annoying and I thought I'd report it.

Just had a new crash on v1.26.5.1 after i loged in and tp`d to a new sim: here is the log.

/later edit: the textures do a strange thing... they randomly become blurry like they try to load again every few seconds, so i opened the live debug log on my screen and it happens when the LLMemory info apears.

Example:
