That's not going to help. The issues are with LuxRender. You need to understand where I am coming from, I am just making note of the fact that acceleration was suppose to make LuxRender 1.5 faster, but I notice just the opposite. Non-accelerated mode seem to me to be a lot faster and the images clear up just as fast. So much for acceleration, in my case anyway.
At this point in time, I will not be falling for anymore hype. I can only hope that in the next version "acceleration" means faster and not slower.
In my case , acceleration works. Render is faster with CPU acceleration than without it . And extra boost option is faster than cpu acceleration. Paolo provides a very good support service,,,. Just my opinion.
I don't think you fell for any hype. It sounds as if everything is working exactly as advertised for you.
If your video card isn't older / lower powered as you mentioned, then you have to expect that it will not perform as good as a more recent / higher powered card. That isn't hype, it's just a hardware deficiency.
If your GPU doesn't have enough memory, then your system will struggle to load the necessary resources into the GPU that facilities the speed boost. In fact I would expect it to be considerably slower if your GPU is struggling to try to perform in a way that it isn't capable of.
You did mention that on CPU alone Luxrender is now rendering faster then it had in previous versions, right?
I don't mean to sound rude, but if your GPU really has only 1 Gig of RAM, shouldn't you consider upgrading? I know that that isn't always possible resourcewise since it can lead to one thing after another having to also be upgraded... But isn't 1 Gig of RAM also below specs for DS itself? I haven't checked the minimum specs recently, but I thought they were a video card with 2 Gigs of RAM.
This is a long thread, I have documented my system many times. I have 16 GBs of memory. I have said I don't use GPU or Open CL, for a long time, and even stated that my GPU is not recommenced for rendering with Reality. Even in my recent posts. So I don't get why you are still going on about the GPU when it pertains to me.
I have been rendering with Reality since it first came out. Every time I have an issue it is always a chicken dance. So I stopped even going for support. I don't blame Reality for all the problems I have encountered, many are due to LuxRender's bugs. Fireflies were suppose to be a thing of the past, sure, OK. So how come I see those still today in some of my scenes? And I know the difference between noise and fireflies. I was told once it was because of the IBLs I was using, incidentally Dimension Theories Skies of Reality (Versions 1 & 2). It seems those IBLs were blamed at the time I brought up the issue last. As I posted here before, there goes that theory. And on and on it goes.
Let's say I go out and purchase a new CPU will the waiting for the noise to clear be faster? That could be the case. Logic tells me that even if I purchase a faster CPU that the noise will still need the extra time to clear, would it not? Now, if I don't use acceleration my scenes are practically clean to begin with and finish faster than waiting for acceleration mode to clear up the noise. That's all I am saying because that seems to be my experience right now. And forget about comparing SPP between the modes. That is akin to comparing apples to oranges, you can't go by that, which is why I myself was seeing scenes render faster with acceleration. I just experienced that when I decided to drop down to non-accelerated mode.
Also, another point, I am rendering simple scenes, go back a few posts I also mentioned this. Perhaps a scene with more objects will be different. I don't know, as I haven't worked on one just yet.
Sorry. Just trying to help out since I could sense your frustration. I too have been using Reality way back to when it first came out.
As you mentioned, it is a long thread and I only went back to the post on the previous page where you mentioned your GPU.
I have a couple of ideas to fix your situation, but you seem to have it in hand and might have already tried them. In any case, I will keep it simple:
1. Turn on noise aware. That resolved a lot of my firefly issues.
2. Try Metropolis. This change fixed a couple of my scenes where #1 made no impact.
3. Try turning on (or off) Extra Boost. Again, for some scenes this helped, for others it hindered, for most there was no change.
4. Turn on and off individual lights to see if one light source is causing the fireflies. This helped with one of my scenes as the fireflies were actually from a overly reflective surface that was off camera.
5. If you have multiple GPUs, try rendering the same scene individually with one at a time turned on. This helped me narrow down a single GPU that was bogging down my other GPU.
And, lastly, when in doubt go into the Luxrender text file that Reality creates. Try changing settings there directly. This helped me streamline the GPU access. Not an ideal solution, but does allow you to cut out the middle man.
...according to the published system requirements, Daz Studio 64 bit (Windows) requires a GPU with a minimum of 512 MB of memory and OpenGL 1,6 (OGL 2.2 recommended). The 2GB minimum requirement is for physical memory.
For Mac the GPU minimum memory is 128 MB (256 MB recommended)
We are talking about Open CL rendering with LuxRender. I don't use it, even with my CPU, too many issues and scenes are not consistent, and besides my scenes don't fit in my video card's 1 GB of memory to even try with the GPU. I need, at least, 1.6 GBs for the scenes alone.
I tried a lot of renders using acceleration with and without boost and it was a no go. The ghosting of a grey film (grey streak I was talking about before) around the figures and shadows is not worth it.
I am rendering with no acceleration.
Im using lux again and iray. Lux is funny in some cases it will give faster times and some cases it does not. For example a scene that had a spaceship with car paint with glass spread out crazy reflection noise (pic 1) I was able to cut it down somewhat changing from Sobol to Metropolis this was using cpu acc no boost Define brush does not work in lux core so one has to wait again for glass and noise to clear up. Cranking up FF removal and clicking noise aware did not help. SSS was turned off since it can only be used with cpu basic non acc to which I have no interest in using. I tried different modes and was unsuccessful. Finally it worked without any noise with GPU boost (Pic 2). I then used GPU boost on another render, some shadow noise took almost 8 hours to clear up. (I let it run overnight while I slept.) Another scene with 5 characters in a forrest was going to take long with GPU boost but cleared up faster using cpu acc no boost. CPU acc boost has some brutal aliasing issues ( pic 3) which is suppose to be resolved along with using SSS in luxcore in an upcoming update... Delphi is right it does not run as fast as advertized...
Totally OT and nothing to do with Reality at all - but where did you get that model of the Spindrift from "Land of the Giants"?
It seems that a fix for this will be coming out in a few days.

LOTG & size fetish related stories is what my 3 deeing is all about. It got noticed by real ex cast members when I had my alternate FB profile a few years back.
I also produced an iray version http://fav.me/d9cfxv2
According the Paolo Reality 4.1.1 that addresses many issues will be out next week. Does not bother me much cause now we also have Iray. 4.1 was a free update..
...still waiting on the bugs being fixed before I bother installing.
Not expecting much though in the render speed category as my system cannot take advantage of the speed boost.
Well I can tell you its no 20X faster but I like the quality it produces. I am having loads of fun using it & iray..
..still, if it takes the better part of a day (or two), I'm sticking with Iray.
My Railway station scene would pobably take a couple weeks in Reality/lux.
I have a AMD FX 6300 and yes, its 20 times faster with extra boost. I I can confirm this, I made comparisons with the previous LuxRender still had installed.
I have 2 newer 32G and 24G systems with GTX980 & 980M I dont see it. As a matter of fact a scene with a side view of the characters next to the ship that took approx 8 hours for dark shadow noise to clear no SSS GPU plus boost. Having said that I still really like the luxrender and use it with iray which is fun. Not all renders take that long..
I am stoked about next week's update...
Looking forward to next week's update as well...
In the meantime, trying to get back into the swing of working on something every day.
Took about an hour to render on my laptop using CPU accelerated only. Exported out the individual images with one light source active in each image. Then layered the images together and post processed in Photoshop.
From what I understand, Reality 4.1 development was focused on making faster cpu render, add gpu acceleration is secondary. That I can not comment property because I havent a decent GPU.
yes, primarily faster for newer and older CPU's (SSE3 and above) GPU is secondary but it's not exclusive to one chipset manufacturer.
I went back to Iray and I am getting 900x900 outdoor scene renders in about 1 hour and 40 minutes on average. It seems that it is only when I have a scene enclosed in a room that Iray gets bogged down. Enough to be almost on par with LuxRender in non-accelerated CPU mode. And I know why, it is all those light bounces inside the enclosed space.
I did run into the shader issue with Iray. I went looking for answers and only found threads talking about the problem. It seems that when I apply a shader to a choker in one of my scenes it crashes Iray. As far as I can understand it seems to be a mixing of shader types(?). Without applying Iray shaders I was able to render it. I can't use it in the scene because it has metal parts along with leather, without the metal shader it doesn't look right (I tried several metal shaders from different vendors).
This thread is one of the ones discussing the Iray shader problem:
http://www.daz3d.com/forums/discussion/56965/daz-crashes-because-of-incorrect-iray-shader-settings
Let's see what Reality and Luxrender can do for me when the update is released. It will have to beat or be just a few minutes within the time it takes Iray to render the scenes. It really doesn't matter which render engine I use as I am using Photoshop to enhance the figure's skin.
I just finished this one, rendered with Iray and postworked in Photoshop:
Thanks for the links. Great work on the iRay scene - the characters are instantly recognisable!
Ha ha I own the boxset so it's easy to model after. Deanna Lund aka Valerie scott hooked me as a young boy. She is the one that I can replicate the best with a pic through facegen genesis target morph. I use Scarlett Johanssen model as Betty. I am having fun going back and forth with lux and iray to create my stories..
Here is another iray scene that I am pretty happy with http://fav.me/d9dbnv4
Im fairly new to iray but apply my Reality / lux approach to it
Earlier tonight I installed the new Reality 4.1.1 and sadly the grey streaks are still there. They are less, I saw them around the chin and cheeks on the face, none around the body this time. This is, of course, with CPU acceleration on.
On a side note, it seems that the more I add to the scene the longer Iray takes. I added tress and a ground and now Iray takes just as long as Reality. And this is an outdoors scene. I need to get my hands on a decent GPU if I am going to get faster renders with Iray.
A let down indeed. Basically if you don't want longer times dont use skin SSS, its more of faster R2.5 at the end of the day. Glitches are still the same for me. I have tried a fresh Reality install, wipe out and re do Reality scene data top no avail. I think your on the right track looking towards iray. Speaking of which I discovered that using Sunlight by removing the map lighting extends render times 3 to 4 hours vs 30 to 45 minues using map lighting as an ibl with an added mesh light for sun effect..
Is it safe to post a mostly negative Reality review?
@bobvan. Strange that you're getting such long render times with sun. Is that the sun/sky you're talking about. I find that very quick.Its far worse then 4.0 they managed to break CPU basic mode. Saving a scene corrupted some of the DS data crashing my video card drivers. We now also have iray so I am not held hostage to this program no longer.
Reality broke the basic path tracer? I didn't notice. Don't think I've touched it since 4.1. Seemed fine then.
I love metropolis for all the pretty caustics, sss and glossy reflections but I think I'm going to pack Lux up again until we see more development on LuxCore. Iray works for me better on my system, so I'm right there with ya.
