TC 2016 Rendering with GPU
Read 6573 times

It was mention in this thread http://forums.turbocad.com/index.php/topic,17996.0.html that we have the option to use the GPU for "real time" renders in the Advanced Render Options. I ran a couple of test in TC 2016 to realize differences in render times.
I used a file I downloaded from 3Dwarehouse, since TC2016 RED is able to handle materials from Sketch UP drawings.

I first rendered the drawing in Advanced Render/GI Fine with standard options (use GPU unchecked). The render time for the drawing was 196s. If I went back to wireframe, or rotated the view, GI render time was still at 196s. During these times, CPU load was maxed while GPU load was at 40 - 60%

I then closed the file, then re-opened it. I changed to Use GPU, in the render manager for GI Fine. Note that after clicking this option the program seemed to freeze for a minute, but then came back. During this freeze, I could see that there was some loading on the GPU.

Next I rendered in AR/GI Fine (use GPU checked). The render time was now down to 48s.  Better yet, is that when I went back to wireframe or rotated the view, GI render time was down to 23s. During this time, CPU load was around 25%, GPU load was maxed.

I think this option to use GPU is available in 2015, and maybe earlier, but I will leave to someone else to do the comparisons.


EDIT::  Whenever you have "Use GPU" set in the render manager, you won't see any progress bar or timer on screen. Everything seems to be done in the background (on the GPU actually) so it may seem like nothing is happening. We I go from wireframe to AR/GI, the display will stay in wire frame until the image is partially rendered (probably the GI phase) then will pop up again fully rendered. During these times, you won't get any info on your tool icons when you hover over them. But when you do, you know rendering is complete. I had to use a stop watch timer to come up with the render times stated above.

EDIT 2:: Note that the above testing was done on my PC which has a GTX 660 with 2G RAM. I tried the same drawing with GI_Fine Tone HDR, but my setup squawked, as GPU memory use went to 95%. Hence the testing with GI Fine. I would hope that a newer GPU such as the GT970 with 4G RAM would greatly improve those times.

Hi I was wondering how to select gpu box in TC deluxe 2016 or is GPU rendering on available in pro version.  I been looking everywhere for render sytles but can find it.

I'd be happy to test the same file with my GTX 970-equipped system.

I've got to admit, though, that I'm having a terrible time with the Use GPU setting on my system.

I loaded the Benchmark provided by Majo in 2014.  With the Global Illumination Fine setting as a constant, it renders as expected in Quality Render mode.  Same for Advanced Render mode if Use GPU is not set.

However, when I set Use GPU, it consistently goes into an infinite loop with CPU usage varying between 24% & 32%.  <Esc> doesn't work (even if the Render Mode selector pops up, it is unresponsive).  I have to kill the program using Task Manager.

With my first file (Redsdk test.tcw, uploaded in another thread), I got somewhat better results in that I didn't get stuck in an infinite loop, but the white object wasn't very white in the renders.

Here is a link to the SKP file I used from 3d Warehouse. I first saved as a TCW file, then did the test stated. I don't have the TCW file here, so you will have to do that yourself.
https://3dwarehouse.sketchup.com/model.html?id=u97ef8930-7a4d-47e3-8c98-2cbc58a23411

Aside: I have been watching prices on the GT 970's and it seems that they are getting less expensive. Once within my budget, I plan on upgrading to the 970. At that point I can compare the difference of a new GPU and my old GPU with only those changes. I have also heard that NVidia will be releasing the next gen GPU 'soon'.

What about after moving or rotating the rendered image, such as holding the mouse wheel and rotating the view? As I mentioned in my original post, the first render was at 48 secs, then down to 23 secs if I manipulated the view. As I understand it, RED is getting closer to real time reanders.

Okay... here are my results:

ACIS Quality: 50 (default)

Monitor size: 1920x1200 & TurboCAD set to full screen (it affects the results for RedSDK)

Quality Render - Global Illumination - Fine
Reported by TurboCAD  1:26
Actual, per stopwatch   1:45

Advanced Render - Global Illumination - Fine WITH GPU
Time until screen updated   0:25  (71% reduction from Quality render - no GPU)
Time until CPU went to 0%  0:38  (64% reduction from Quality render - no GPU)

Monitor size: 1920x1200 & TurboCAD set to about 1/9th screen (see attached image)
Time until screen updated   0:22 (WITH GPU, 12% reduction from full-size TC display)
Time until CPU went to 0%  0:26 (max, maybe less, 32% or better from full-size TC display)

TurboCAD back to full screen

Advanced Render - Global Illumination - Fine NO GPU
Time until screen updated   1:03  (+152% compared to GPU)
Time until CPU went to 0%  1:49  (+187% compared to GPU)


Notice there are obvious differences in the results between these two render settings (GPU or no GPU).  For Global Illumination Fine, Quality and Advanced have the same appearance if the GPU is not used.

Also, when I rotated the image (approx. 90 degrees around the front of the car) while using the GPU, the new image appeared in just a few seconds (maybe 5, but I wasn't paying attention to CPU usage to confirm.

EDIT
*************

When I rotated the view by approx. the same amount with the GPU OFF, TurboCAD reported 117 seconds to re-calculate.

Thanks Jeff and Ken for the info.
These test show the significant improvement in using GPU for RED rendering versus just the CPU. And you confirm the significant time to re-render a scene as I first reported. It also shows on improvement of the 970 vs 660 GPU of about 20% reduction.
My guess using GPU render will significantly improve Animation Lab times in creating movies.

I gave the race car skp file a try on my Vista workstation and the Windows 10 laptop. With "GPU" checked, it won't render. In Vista in just goes into some sort of loop; flashing between several views and never actually rendering. I had to kill the program. In Windows 10 it started to render, then locked up; no cursor or keyboard. After 5+ minutes of that I had to kill the computer. Without "GPU" it renders in around 7m 30s for Vista and 6m 48s for Windows 10. I guess this means I would need a computer with 24 cores & max RAM and a video card with 24 GB of memory to use 'all' of RedSDK's features. I don't see that happening.

Hi guy's, when I rotated the scene, there was jerky movement of about 2-3 seconds, though there wasn't any breakup in the scene. depending where I stop the rotating, the render ranged between 36, 42 and 44 seconds

I expect that the problem is due to the RED engine expecting an NVIDIA GPU and your laptop uses another one (say, Intel).

I take down this car as a 2015 SKP, saved as a tcw, render in Q/ GI fine ( 8 treads ) and A/ GI fine, ( 2048 treads ) default render, both case was 23-24 sec, turned on GPU, after the calculations ( 20-25 sec ) it used like 1-2 sec to put it up.
At first i think it did not work fully, before i realised, dang it was finish :)

John, I would say that the biggest improvement that you can do to your systems, is to upgrade to Win7 or Win10. Vista is arguably the worst operation system put out by Microsoft. You can still get Win7 Pro64 for about $140, or Win7 Home Premium for $110 if you don't want Win10.

The laptop has Win 10 (the upgrade from Win 8.1), but I need to try out a real "full version" of Windows 10 at some point because the upgrade is so slow compared to Win 8.1. I would say the Windows 10 upgrade is the worst piece of crap put out by the clowns at Microsoft. Vista has served the 'big machine' well these past 7+ years, but I know it's past its prime.

John, how is your harddrive space, try to leave about 25 % free. I know some people place all the blame on Windows. I was glad to leave Vista and go to Windows 7 which I think the to best Windows system. I have used Win 95-Windows 10. Wouldn't even touched Windows 8. Windows 10 is a good system, comparable to Windows 7, but people have realize that the other half of the blame is hardware/driver compatible with Windows. I learn this building computers during the Windows 95-98 SE era and not the mention using the computers in the 1980's.

John,
  ;D I got the exact same results as you, redstuff crapped out.
Lightworks worked with this model. 7 secs to render RT full. Redsdk can't do everything :P and it's nice to the option to use Lightworks.
The talented artist who created this drawing must have put a lot of time into texture mapping so I wanted to point out a few things that Turbo did not translate during the import. I needed to UV map a few decals and make some tweaks in Turbocad. Attached are the images displaying the errors, my fix and the original as seen in Sketch up Pro.
Ok, so back to ‘USE GPU” >
Use gpu ON > I would pay close attention and look carefully as to what is happening when this is ON.
I lose the “IOR” with my materials and sometimes I need to re-adjust all my materials, lighting and environments. So, I pretty much gave up on it from the start. The renders don’t match up to the quality of when it’s OFF.
You can create “quicker render styles” (lesser quality) by adjusting some of AR style parameters. I use these sometimes to get a quick preview with texture,light and reflections. You can also use Redstuff "Draft" for quick preview when applying textures, no reflections and minor light adjustments and shadows with point and spot lights.
