A Warning to Engineers and Animators, Regarding Vista

Okay, bad news:

Vista offers no OpenGL support, which means that CAD and 3D modeling programs (i.e. Solidworks, Pro/E, Maya, 3D StudioMax, you get the drift... ) run extremely poorly. This is according to Tom's Hardware Guide at link: http://www.tomshardware.com/2007/01/...ta/page11.html.

The actual benchmark results are here: http://www.tomshardware.com/2007/01/...sta/page6.html. *

Additionally (as has probably been discussed to death), Vista takes a slight performance hit in about every application and synthetic computing benchmark.


*) Results current as of Jan. 29, 2007

Here is something from Kakaze in another thread: (http://www.notebookforums.com/thread197474.html)

An application can use the default implementation, which translates OpenGL calls into the Direct3D API and is frozen at OpenGL version 1.4, or an application can use an Installable Client Driver (ICD), which comes in two flavors: legacy and Vista-compatible. A legacy ICD, the kind already provided by independent hardware vendors targeting Windows XP, will disable the Desktop Window Manager, noticeably degrading user experience under Windows Aero. A Vista-compatible ICD takes advantage of a new API, and will be fully compatible with the Desktop Window Manager.[23] At least two primary vendors, ATI and NVIDIA, are expected to provide full Vista-compatible ICDs in the near future.[24] However, hardware overlay is not supported, because it is considered as an obsolete feature in Vista. ATI and NVIDIA strongly recommend using compositing desktop/FBOs for same functionality."
Does this mean that ATI and nVidia will step in where Vista fails to perform? And how does this affect Intel Integrated graphics users? Also, does anybody know the timeframe on when we will see this third party OpenGL support in Vista?

ATI and nVidia already have stepped in, long ago. OpenGL runs just fine under Vista if you have drivers installed. thats the way OpenGL has been previous as well, the actual OpenGL is done by the drivers from the card manufacturers, the basic drivers Microsoft provides support little more than necessary.

going off information from the day before retail launch as a base for the state of things today is a little blindsighted, I think. at least ATi didn't have OpenGL support ready in their Vista drivers until a day or so after launch

Thanks for the info. I hadn't gotten the memo, just going off what I had read.

So all that good professional modelling software and CAD stuff should run just peachy now right?

should run just fine. in fact in my programming demos I get better framerates in OpenGL than DirectX on my Vista machine
