View Full Version : No OpenGL capability in 3.0 - can I go back to 2.5?

Hi,
I've just updated to 3.0 and found that my VM (Windows XP) now has no OpenGL capability!
Using glview (http://www.realtech-vr.com/glview/) shows NO OpenGL drivers installed! Yet, everything was fine with 2.5. This is rather important, since I am a software developer writing OpenGL applications!
Is it possible to revert back to 2.5 so I can get on with my work?!
Cheers,
Steve.

My XP VM shows OpenGL support up to version 2.0, based on my Geforce 7300GT, and other users with limited Intel graphics have 100% up to version 1.4.
Are you sure you have enabled 3d in Parallels? There's a checkbox for DirectX in the video properties tab for the VM, and this may also enable OpenGL.
PS. Hmm. Forget that. Just tried it with DirectX checkbox turned off and I still get 100% support at v2.0

Did you installed Parallels Tools? Anyway - try to reinstall it again - it can solve this problem.

I have the same problem as Steve: no Open GL support.
I can update the video driver via the windows control panel, which fixes Open GL (probably only software emulation?), but then the Parallels integration with OS X is broken. Reinstalling the Parallels Tools breaks Open GL again.
System Info: Mac Pro, 1GB RAM allocated to parallels VM, 16MB VRAM, DirectX enabled. I am using Parallels with a Bootcamp partition with Vista Ultimate installed.
How can Open GL support work on some machines and not others?
Chris.

Yes, but no luck.
I then updated the driver via the normal windows control panel. OpenGL works again, but now the Parallels integration with OS X is lost (I get two mouse pointers, window resize does not change video resolution of virtual machine, etc).
When I reinstall the Parallels Tools, OpenGL stops working again.
Cheers,
Steve

Thanks for that link.
When I enable 3D graphics in Parallels, it shows the graphics card as "ParallelS over ATI Radeon X1600 OpenGL Engine" And it works, albeit much slower than on the mac natively by a factor of 5.
I'm doing some OpenGL development too and I'm finding that these simple demo applications (like the OpenGL examples from wxWidgets) work fine in Windows directly, but do not work at all under Parallels.... they even crash Parallels completely (which is a total bummer if you've got something else going on in Windows in the background).
Cheers,

Make sure you did not install DirectX after you installed the Parallels tools...
A 'stock' DirectX install overwrites a bunch of files Parallels installs in order to make OpenGL and DirectX work.
I've tested some of my own DriectX code, and it does in fact work with hardware support if I'm using extensions that my hardware supports.
That being said, Macbook hardware does not support very many extensions (version 1.2 is complete, everything else is broken).

Thanks, but I haven't been doing anything with DirectX - it's OpenGL I'm having problems with.
But I have found something - if I turn the hardware acceleration slider down to one notch above off (Display Properties > Settings > Advanced > Troubleshoot), then OpenGL will work. Albeit *really* slowly!
Cheers,
Steve.

I cannot do this. In fact, I see nothing in my display control panel that makes any reference toOpenGL. Where do you do this?
System: MB Pro SR flavor, Parallels with XP

This made no difference to me, when I tried it. I cannot get Maya to work and Studio Max has error with OpenGL Initialization.

Rhino 4 only seems to work with "use accelerated harware modes " option under OpenGL turned off.

this is very very very annoying.
i was really enthusiastic about this version and thought it was worth the money but now i'm just getting angrier that parallels promised something that they couldn't deliver.
it can't be that 2.5 was better in terms of open-gl than this 3.0 which promised much better 3d/ open-gl graphics support. can't even start my 3d tools anymore.
*sigh*
hope someone finds a good solution to fix this before we have to wait for weeks and weeks until an update might fix this issue.

See this post (http://forums.parallels.com/post66673-61.html) for my results when running CineBench, an OGL bechmarking test.
I don't pretend to understand all this stuff, and I have no applications software that depends on OpenGL, but it appears from these tests that Windows XP under Parallels runs OpenGL SLOWER in hardware mode than in software mode, and neither mode comes anywhere near the native h/W or S/W performance of OS X OpenGL.

so why did parallels deceive us then?
this is absolutely unacceptable. i could have a little bit of understanding if it was at least as fast/ slow as 2.5. but not not working altogether or slower.
really frustrating

THIS IS a serious issue.
why would i want to go back to 2.5 when i paid for 3.0 and expect it to work?
i can't even run my 3d tools anymore. i upgraded to 4128 and this issue is still there.
