Hello

Im trying to find a way to update OpenGl on my second PC.
I dont know if there is anyother possibility than updating the driver?

Its possible to update directly OpenGl?

*My 2nd PC have 1.4 version and i notice (because updating a driver the last week on my main PC) that there is some 3.x OpenGL available.
My problem is that updating the driver on the second machine gives mne a problem with the monitor (LG 500g) and i cant find yet a driver for the monitor, so im seeking if its possible only to update the OpenGL without need to update my videocard driver.

Thanks for your patience!

OpenGL is included with your video card drivers, I think. Sort of like how newer versions of DirectX only work on newer cards.

OpenGL is built into your graphics card. There is no driver or software update for this. You'll have to buy a new card.

Sure, but from most companies, if you download a newer driver, many new features will be emulated. Only the supported part will be hardware accelerated then.

Yes this is true, because in fact all graphic boards emulate OpenGL.

Native OpenGL graphic boards are very expensive

Afaik 3dlabs had some of them, but 3dlabs doesn't exist anymore (Its ziilabs now, but they don't even host the glslValidate tool anymore).

I've updated my GPU charts http://emsai.net/reviews/gpu/
Nvidia and AMD cards should have the proper OpenGL supported listed as per the latest drivers.

Nvidia has OpenGL 3.0 available in their latest drivers for their latest cards,
AMD has 3.0 avail for their latest cards. Older cards from both only have driver support for OpenGL 2.1 or 2.0

Pretty much all AMD and Nvidia cards with DX10 and Shader 4.0 seem to support OpenGL3.0 (if you got the latest drivers).

@Rescator

Is your GPU chart correct for the Radeon HD 4870? The AMD page for the 4870 > http://ati.amd.com/products/radeonhd4800/specs3.html says it only provides OpenGL 2.1 support, Or am I mis-understanding what your saying on your chart?

That's the original "specs" sheet.
I got my info from wikipedia's list of Radeon cards, which got it from here:
http://fireuser.com/blog/welcome_to_the ... _from_amd/

The R600 and R700 series should support all or almost all of OpenGL 3 in hardware, older cards support it though emulation I guess? Not sure how the ATI drivers work really.

The point is, if you got a DX10 capable card, update your drivers to ensure you got OpenGL3, same goes for Nvidia owners. Again, look at my chart, the info for Geforce have been updated too.

If any cards on my list does not have OpenGL 3.0 listed then they do not support it, or ATI or Nvidia do not support it through the drivers available today.

Now! If any games support OpenGL3 is another matter. I suspect that some 3D apps that support DirectX 10 might support OpenGL 3 though.
