Beware of windows 8

thomthom

on the other hand, who wants to use an OpenGL based 3D modeler on a lame netbook w/ a shared and thus slow graphics 'accelerator'

Yea - I don't do work on it. But I bring the notebook when I'm on the go - like at Basecamp. I had to boot back into Win7 for my presentations. But seeing how Win7 has OpenGL support I'd hoped that Win8 would as well.

I used Windows 8 on my laptop at basecamp, ran Sketchup and Thea seamlessly. I have 8400M dedicated card however if that makes the difference.

Hi again

First of all... About the iMac vs Windows-thing:)
You don't get a much better picture than on an 27 inch iMac;)
The downside to that is that I bought my licensed Sketchup and vray back when I only had a PC, but with bootcamp and windows 7 on the mac, everything was working just fine.

I found the problem. It is the video card (AMD Radeon HD 6900m) that's causing trouble (or at least I think it is) anyway, I can't turn on the "use hardware acceleration" button. I have tried updating the graphics card but nothing happens... unfortunately:(

Tried updating to this driver: http://drivers.softpedia.com/get/GRAPHICS-BOARD/AMD/AMD-Radeon-HD-6900-Display-Driver-8982108000-for-Windows-8.shtml

...or download directly from AMD.

Hi silverwingsltd
I am having the same exact problem you describe here. My sketchUp runs super slow on my newly installed windows 8, and I'm not able to use the "hardware acceleration".
Have you been able to find a solution? Please share if you did.
Thanks

What graphic card do you have? Have you installed and updated all your drivers?

Hi, my laptop has "mobile intel 4 series express chipset family). I did update the driver to the latest for Windows 8 (WDDM 1.1). But my sketchUp is still super slow, and the open GL acceleration is still grayed-out.
However, yesterday I did more research and read in a gaming forum that some of these drivers do not support Open GL yet on Windows 8. And the way to fix that was to adjust your startup to load the driver for Windows 7, and open GL should run fine like that.
I have not had the guts to give that a try though. any suggestions?

Here's a discussion about it:

SU does - as any other OpenGL based 3D modeler - require a fully and mature OpenGL v1.5+ support. Which shared/integrated grapics subsystems of e.g. office desktops or low-end notebooks simply do not provide.

This same exact laptop and graphics card had windows Vista before and I never had a problem with sketchUp. I was able to select the OpenGL acceleration and all my models ran smoothly.
I've been having the problem ever since I upgraded to windows 8, so your above statement is not necessarily true.
Just want to figure out how I can get it to have the GL support again, read somewhere that I could revert just the driver back to windows 7 and it should work, but no luck yet.

UPDATE, finally got it to work
the driver straight from Intel, version Windows 7, was not working for me... But I went to my laptop's manufacturer website and downloaded the driver there, and that fixed it!! Now I'm running Sketchup smoothly on Windows 8 with the graphics driver for Windows 7, and my openGL acceleration is available...

Still hoping for drivers for my laptop...

the recent intel HD Graphics 4000 is definitely better than Thomas ol' GMA 4500 but surely still no first choice for high poly count models.

many current notebooks (make/model?) do have 2 graphics subsytems integrated, the lame/integrated but powersaving intel HD graphics is used for office/internet/video stuff and the fast/dedicated but powerconsuming GeForce or Radeon is activated if processing of e.g. 3D graphics output accelerated by OpenGL is required.

For doing this the appropriate video driver for these hybrid graphics solutions needs to be installed, which is typically distributed by the manufacturer of the notebook.
