Hardware recommendations

tald311

I am not sure what SketchUp uses as hardware. I use gaming systems for modeling since they are designed for handling 3D models.

The only thing I am sure about SketchUp is it is single-core and that is because of the real-time rendering stuff. One of the Devs explained it to me but I am not that tech savy (so take this whole e-mail with a grain of salt).

The system that I just bought is this one:

I know that RAID drives is recommended for some 3D games. And since I am a gamer (added bonus) I look for the most intensive graphics games I can find and see if my system can run it.

The current problem is VISTA and Shadows buts that only limitation I have run into. I am hoping SU 7 responds better to Vista since we do not have a choice any more but to use it.

I do know with Vista that JPEG snap shots I cannot take in XP, I can in Vista with high-rez. Your system does need to be designed for 3D graphics though – what ever that might be, which is why your survey is a GREAT IDEA!

Thank you again.

I have a 256 mb Ati Radeon (I think X550) card in my desktop. I cannot really speed things up with hardware acceleration but get along with it pretty well. Some people have issues with ATI cards however so wait till a more experienced "hardware guru" chimes in.

copain

anyone uses radeon hd4850 for sketchup?
i heard radeon cards aren't very compatible with openGL apps..

thx for the fast reply gaieus, and anyway this is my 1st post.. nice 2 meet u all

Great idea for the hardware survey! I wish it would've been done before I upgraded my machine. I ended up going with the HPm9340f. For less than a grand, I got equipped with an Intel Q6700 Quad core, 6 GB ram, 750 GB HD and a NVDIA 9500GS with 768MB dedicated video memory, upgraded from a AMD 64 bit processor. I've seen a drastic improvement in handling large models in sketchup and it's cut my render times down by almost 80%. It's a good "bang for the buck" machine if anyone is undecided. I would still wait for Tommy's survey though.

What a great idea- I filled in the survey.

Hi All

I am new to the forum and this is my first post! Hurrah! Just want to say what a fantastic job you guys have done to keep this forum fresh and relevant.

I am looking for a new desktop computer so this thread is very useful to me. Having filled out the questionaire I would like to make a comment that some of you probably have picked up already. From my experience rating performance of your own machine is too subjective. It would mostly depend on the level of complexity needed in the individual modeler and therefore relying own their own judegement is perhaps not the best way to go about this. Perhaps there should be a collection of models for download with increasing complexity and let people note down each model from the lower end until their computer starts to show jerkiness on screen or show serious slowdown then post which model did it. Just a thought

Gaieus

You are perfectly right about this (and welcome, by the way) but I hope that at least some basic data will be collected now.

We also used to have topic about performance and there was a file with several scenes and more and more instances of the same component in those scenes (on layers). It was interesting to see how different machines performed.

plot-paris

is there a way to show the framerate, with which SketchUp is displaying the model, when moved?
because that would be a very objective figure. (or is it possible to write a ruby that does that)

just click through the scenes in the test file (complexity increases). then there are some "framerate test scenes" where the complexity doesn't increase, so that you can have a look at the framerate when moving the model.

dumb question: are there different model-types or -settings that effect different hardware components (like styles = gpu, poly-count = cpu and ram...)? the test file should mind these factors as well.

...now that I think of it. could't one of the ruby masters write a script that produces a text file with framerates achieved during the test? then we could open the test file, start the ruby, start an animation (with scene delay). when the animation is finished, either upload the text file here or post the results...

Jackson

Now that's a great idea Jakob! Not subjective and not restricted to very low-end or very high-end systems as some "can you run this skp animation?" based tests are.

plot-paris

we just need someone to write a script that puts the framerate in a text-file (I have unfortunately not the slightest idea of how to do anything in ruby).
the best way to put it, would be something like:

scene1 to scene2 = 76 fps
scene2 to scene3 = 44 fps
scene3...

and then we need a nice test-file that not only tests your hardware, but also makes testing enjoyable (like starting with a small village with few simple houses, going to a city of decent size and finishing with a huge capital (loads of polygons) with a big castle or cathedral in the centre...

(that is a nice idea for the competition thread)

[Edit] I just used an old model to demonstrate, how such a scene could look like. of course it would be much more enjoyable, if you had a bit more variety... but as I said, this is only a first idea[]

I just spotted a problem (I think). how much do components affect cpu and ram? because the file size should be rather small for fast download - therefore should consist of components... but can we test all necessary information with that?

The old gold standard test file (all those peeps) is pretty small...right? Also, isn't important to run thru the pages once to load as much as possible in whatever ram is available...I get different results second time thru?

Not entirely sure what the question is but my understanding is that components will make the saved file quite a bit smaller, however once the drawing is open they make no difference whatsoever in terms of fps.

didn't know that. but just tried it out and you are right! wonderful!

another thought: we have to ask people who do the test to shut down all other software. otherwise the results may be influenced negatively...

[Edit] and yet another thought: does all the grafical calculations like styles and shadows solely depend on the gpu? meaning that the cpu only has to calculate any geometry modifications. can't you seperate the processes like this?
(sorry if this question sounds stupid. but I have no idea of how such things work... )

Tommy,

Welcome.
Thank you for this survey. I think its a great idea.
I am currently using a VISTA Laptop (Core Duo 2.4, 4 gigs ram, NVIDA GeForece 8800M and Raid hard drives) and it handles SketchUp in ways I did not think was possible. I have very large models as well (1 million to 3 million faces) and it was jaw dropping. Its not perfect with Vista for something’s but I have a feeling the RAID is making a difference.

Thank you
Daniel Tal

How many MB are the models? We have models in the 40-60 MB range about 1 1/2 million edges & lots of component instances. My video card is NVIDIA Quadro 1400 FX.. I suspect it is the key problem for me at least. Our models would be next to impossible to simplify, but working in them right now is excruciating slow. We are due for new computers anyhow and are interested in getting the top of the line - or anything that will make life a little bit easier.

That's pretty much my understanding. I've been running my own benchmarks lately using a model I did that's 3.3MB. In the ruby console I run Test.time_display and it'll rotate around your model 360 degrees in exactly 72 frames. Afterwords it gives you a little report w/ some useful info. I'm finding it very handy to see exactly what kind of performance hits SU takes from tweaking various things (clock speed, resolution, hardware acceleration, fast feedback, anti-aliasing, etc.). I write down my settings and then run 4 tests (all 4 combos of textures on/off & shadows on/off).

I'm running on a 3.4Ghz Intel Pentium 4 HT w/ 2 gigs of RAM and an nVidia 8800GT graphics card at 1600x1200 resolution.

Here are just a couple results which should address your question.

Hardware Accel. turned ON in SU.
Textures: OFF
Shadows: OFF
23.3 frames/second

Textures: OFF
Shadows: ON
1.2 frames/second

Textures: ON
Shadows: OFF
18.6 frames/second

Textures: ON
Shadows: ON
1.1 frames/second

Hardware Accel. turned OFF in SU.
Textures: OFF
Shadows: OFF
7.2 frames/second

Textures: OFF
Shadows: ON
0.2 frames/second

At this point I stopped testing w/ hardware accel turned off because that last test took almost 7 minutes, whereas the other one's were either taking about 4 seconds (w/ shadows off) up to a minute (w/ shadows on).

Before doing this test I'd heard that the graphics card basically just does shadows and textures while the CPU does the geometry. Nevertheless, unless I'm missing something (?) the graphics card helps out a ton even w/o textures and shadows turned on.

As a side note, I'm going to run some tests on a coworkers computer when I get a chance. He has the same setup as me with 3 gigs of processor speed instead of 2. Be interesting to see what difference that makes.

Couple other odd things I've found so far...

Overclocking my card didn't really do anything. Some results were slightly worse, some slightly better. Probably well within the margin of error.
Turning Fast Feedback OFF actually improved my FPS by about 30%
Turning my anti-aliasing up (from x0 to x4) either didn't affect performance or may have actually improved it slightly.

These are all pretty counterintuitive to me but I've yet to be able to explain them away given the results I'm getting.

I'd missed this post before with your benchmark file. I ran the ruby I mentioned ( Test.time_display ) with shadows and textures on (although I don't think there are any textures) a few times and got an fps between 23.0 and 23.5 in scene 1. In scene 7 I got a 0.2 fps which took an agonizing 404 seconds to cycle through. Even without shadows on I only got a 0.5 fps which took 158 seconds.

wonderful, thanks a lot for sharing your test results, Brodie.

I think that is bringing us a huge step closer to what we want. did you just type the command into the ruby console? so this function is already implemented? then it should be really easy (for a ruby guru of course ) to automate this process...

oh, and you pointed out another important thing for the test file - textures and styles...
and the hardware settings (acceleration, fast feedback, anti aliasing - I don't think you can change those with a ruby script. perhaps everyone has to go to the same settings or at least report which settings are active, when he runs the test)

I will try and run the file with this test as soon as I get into the office...

How did you find out about that? That's fantastic! I attach a quick test file- no point making it huge as that'll just bring older machines to a standstill. Just follow the instructions in the file and post the third test result here. Anyone know why it runs slow the first two times then evens out after that?
