Selection box has gone haywire after upgrade to Windows 7

mikeewilly · 17 Jun 2011, 18:09

I'm currently running a Dell Latitude 630 with an Intel 965 Express Chipset. When I ran SU8 under Windows XP I enabled OpenGL Hardware Acceleration and everything worked fine. Last week I upgraded to Windows 7 32-bit, re-installed SU8 and my plugins and now I don't have any selection box at all with Hardware Acceleration enabled. If I disable Hardware Acceleration I get the selection boxes but they paint VERY SLOWLY. This is very painful.

I've checked display driver and Update Driver reports it's up-to-date. I've also looked at the OpenGL properties in the Intel Graphic Properties 3D Settings and they are at default values.

Does anyone have any ideas? SU8 on this laptop is my lifeblood and I'm dying....

Thanks,
Mike

Update: Still no idea why it happens, but if I change the "color quality" on the video card from 32-bit to 16-bit, the problem goes away.

Go figure.

Very strange behaviour. Dropping down to 16 bit usually results in other undesirable features...like having a box around the cursor.
I'd try disabling fast feedback before hardware acceleration. It might just cure the problem without the loss of performance.

From what I have read here, the Intel on board chip set is problematic. Maybe your old OS's implementation of OGL worked well with SU8, but not the new OGL, which is part of the new OS. You could try to down grade the OGL (I have no idea how to do this). However, the least expensive graphic card will often work with OGL enabled.

I actually tried disabling fast feedback before I tried backing off to 16-bit. Backing off to 16-bit was a last desperatee attempt to get my selection box back and backing off to 16-bit hasn't resulted in any other undesirable behavior.

Have you updated your Graphics-card drivers ?
What is you card?
If you disable ALL of the possible Preferences > OpenGL check-boxes, is it 'fixed' [but slow!] ?

Yes. The graphics card driver is the newest one available for Windows 7. It is an Intel 965 Express Chip mounted on the laptop motherboard.

Yes, if I disable ALL of the possible Preference > OpenGL it is fixed but slow. (Too slow)

To quote Google...
Sketchup requires a 3D class Video-Card with >=512Mb of memory.
The card's driver must support OpenGL version 1.5 or higher, and be up to date.

Have you looked at your card's control-panel settings - e.g. many to allow 3d applications to take control rather than use presets etc...
