[gameprogrammer] Re: Windows Vista and OpenGL

Are you using the right NVidia drivers?

By default Vista will do OpenGL software rendering,
if I'm not mistaken.

I've had a similar problem on the same hardware with a simple "2D"
game I'm developing with my team, we use OpenGL for emulating the 2D
(and also to have its features such as lightning, zoom and so on) and,
somehow, the code in Vista ran HELLA SLOW compared to Linux and XP...
I dunno why.

I think I read somewhere that they nerfed up the whole OpenGL
libraries in Vista so OpenGL didn't have as much power as D3D did, but
I think it's just a matter of DLL replacement.

If you find a solution, please share it! :D

Hi All,

 I have moved to Windows Vista and I am seeing a significant difference
 in the results of running the same code on Windows XP.  Specifically,
 the rendering quality seems to be off.  Difficult to describe but I am
 seeing a lot of flicker when rendering that I was not seeing before
 and it doesn't appear to be because of the performance of the
 computer.  The flicker only seems to occur when moving.  If I leave
 the scene in place it renders OK but then when I rotate some objects
 in the distance flicker off and then back on.  It is as if they
 sitting on a clipping plane and flipping from one side to another and
 it only seems to be on the farthest objects from the camera (Have I
 just answered my own question???  Will check...)  The XP machine is
 about 3 years old (Tosh laptop/nVidia Chipset) and runs perfect.  The
 Vista machine is a brand new IBM/Lenovo with nVidia chipset.  Although
 the video adapters are different they should be comparible and the IBM
 should be a little better.

 I was just wondering if any of you have had similar problems coding
 for Vista with OpenGL or anything else for that matter.  Am I doomed?
 Do I need to switch to Direct3D?

 Regards

 Richard
