SketchUp LENT ! Analyse Sketchup 2019 sous Checkup 2017


J’ai décidé il y a quelques mois d’acheter SketchUp pro 2019 dans le but de l’utiliser d’une manière professionnelle.

Seulement lors de l’utilisation de SketchUp et Layout j’ai l’impression qu’il n’utilise pas toutes les ressources de mon ordinateur après avoir mis quelques textures, le modèle devient extrêmement lent.
Je vous parle d’un fichier qui n’excède pas 4 MO. (je trouve cela frustrant ! ).

Voici ma configuration:

  • HP Z440 Workstation
  • carte graphique: NVIDIA quadro P4000 (ce n’est pas rien)
  • RAM: 32 Go

J’ai d’abord bidouiller dans les paramètres avancés de ma carte graphique NVIDIA en suivant des tutos sur internet pour utiliser toute sa puissance… mais rien ne change.

J’ai donc décidé d’utiliser le logiciel CheckUp 2017 pour déterminer si sketchUp utilise bien les ressources totale et maximal de mon ordinateur… Et en effet il y a plusieurs problème assez étonnant:

Que dois-je faire ?

Pouvez-vous m’éclaircir, merci.

Checkup exposes a bug in the Windows reporting system for graphics card information. This doesn’t automatically mean there’s a problem with your system.

In SketchUp, go to Window>Preferences>OpenGL. Click on Graphics Card Details. Does it show the Nvidia graphics card or something else? Make sure the drivers for the Nvidia graphics card are up to date. Your computer probably also has an integrated graphics card. Go to the manufacturer’s website and get their latest drivers to install. Don’t just check with Windows to see if the drivers are up to date.

Keep in mind that SketchUp will only use a single core of the CPU. It doesn’t matter if there are 4 or 4000 cores. What does matter is the speed of the processor.

Perhaps you could share a typical file that you see performance problems with. Maybe we can compare on our computers and see what we see.

Merci pour votre réponse rapide

Voici ce qui concerne openGL
open GL

Mon processeur:
Intel® Xeon® CPU E5-1650 v4 - 3.60GHz - 6 coeurs - 12 processeurs.

Voici par exemple un fichier qui est fort lent à travailler.
dressing.skp (4.0 MB)

Les pilotes de ma carte graphiques sont bien à jour:

Pourquoi le rapport CheckUp serait-il faussé? Je ne comprends pas.
J’ai l’impression de travailler sur un viel ordinateur lorsque je travaille sur sketchup, c’est frustrant.
J’ai acheté le programme, j’ai investi dans un bon pc, et j’ai des soucis de lenteur…

Merci pour vos réponses

CheckUp only reads and displays what Windows reports for the graphics card. There’s a bug in the Windows reporting system that is shown by CheckUp. The flaws in the paint on your car aren’t caused by the light. The flaws are only exposed by the light.

While the Nvidia Quadro graphics are nice and expensive, they don’t seem to be as robust in OpenGL support as the GeForce and GTX graphics cards. SketchUp requires the robust OpenGL support.

I opened your SketchUp file and I don’t really have any difficulty with it I have an older GTX970. I can orbit and zoom around your model with ease even with textures and shadows turned on. There are some things you could do to make working in your model easier. Leave shadows turned off and work with the face style set to Monochrome. Also keep the model clean. I just ran CleanUp3 on your model and got rid of a fair amount of stuff.

You could also use an extension called Skimp that would help to simplify components like the jackets. You might also consider doing things like using plain colors instead of the carpet textures on the clothes.

FWIW, you should also correct face orientation. No exposed blue back faces.

I have NEVER had any OpenGL problems with any Quadro cards that I have used. Years ago Nvidia had a faulty driver release that hampered SketchUp use, but that was with Geforce cards. The fault with Quadros is the poor price/performance ratio compared to GeForce - the electronics inside is essentially the same. Windows updates seem to break the Nvidia drivers for both card types with the same frequency.

As to the problem, it shouldn’t arise from the hardware. I can orbit the model quite well on my new computer that is in practice only marginally faster than yours. Also the polygon count, while large for a model of simple cupboards and shelves (the edges and faces are in your towel stack and suit components) is not too staggering. Are you running many SketchUp extensions? Vray? Too many extensions, especially of the type that keep all the time monitoring what you do, are often slowing down SketchUp. Also, in some situations, keeping the Outliner open can cause slowdowns.

Is the monitor connected to the right socket?


Merci pour votre réponse et vos précieux conseils. Devrais-je alors investir tout de même dans une carte graphique pour qu’elle prenne en charge plus facilement les aspects d’OpenGL?
Je vous ai fait une vidéo pour que vous compreniez la latence de déplacement que j’ai avec ce fichier. Dites moi ce que vous en pensez, si c’est normal, et si pareil chez vous?

Une vidéo parle plus que des mots. (je n’arrive pas à la partager…)

Bonne journée.


Merci pour votre réponse, oui j’utilise Vray, mais il est éteint lorsque je ne l’utilise pas, donc l’asset éditor et la frame buffer ne sont pas ouvert.

Alors oui mes écrans ne disposent pas de prise HDMI pour se connecter à ma carte graphique P4000, j’ai du ajouter un adaptateur DVI - HDMI (ou displayport? )
Cela pourrait nuire aux performance peut-être ?

Hi Anssi,

I’ve always seen everyone recommend GeForce over Quadro. Is this simply for the application? My understanding is that the Quadro cards are really good for their CAD program ability. Is it just the way Sketchup is compared to other CAD software? (Solidworks/Inventor/etc.)

Is it just a poor price/performance ratio for Sketchup? At work, my sketchup setup is amazing with a Geforce, but if I were in the market for a graphics card for home where Solidworks takes priority with a little Sketchup on the side, the Quadro series would probably be a better alternative correct?

Thank you.

Mainly just that, and the same goes for most standard 3D/CAD/BIM applications. There used to be optimized Quadro drivers for applications like AutoCad something like 10 years ago but they have been discontinued. Some expensive apps like Solidworks and Catia might still benefit but I am not sure about even them. Others get along just fine with “gaming” cards.

Thank you. I’ll have to do some more research on the Solidworks side.
