OpenGl crashes

[Grant Swanson]

OpenGL has very few good uses in After Effects. With the exception of working in 3D (and even this isn’t always smooth), you’d be better just turning it off altogether.

I will also add that the nVidia Quadro line of cards work much more smoothly with OpenGL than the GeForce line…so if you can switch like you say you can, it may or may not be worth a shot.

Again though, OpenGL is really only meant for 3D in After Effects, and it doesn’t always do a great job on that.

Thanx for the reply grant
well after playing a bit with 3D scenes it runs much better with the Opengl on then the adaptive resulution
and on other scenes its the other way arround
Quadro video cards are more expensive and as you say Opengl doesnt work that good so there is no need to pay more then what i have now
but i can get a different card in the same value of this one
i red here about radeon X1950 is it better then the one i have now?
or should ill stay with what i have
thanx

Hey guys so what do you think should i change my video card to the radeon X1950?
thanx

I have a dream…

where Adobe finally makes AE uses CUDA/OpenCL to REALLY accelerate our works…

But i’m still dreaming…

“…should i change my video card to the radeon X1950?”

According to Tomshardware.com’s latest Graphics Card Hierarchy chart, the Radeon X1950 is a few classes above the GeForce 8500GT. So if you can change the latter for the X1950 without additional outlay, I’d say go for it.

BTW, OpenGL itself has various versions and within every version there are a myriad of sub-sets which an application may implement, or choose not to. The graphics card a user chooses would have to, as a minimum, support the same sub-sets of OpenGL that the application has chosen to implement. Else there will be incompatibilities probably resulting in crashes. I do not see any details of the OpenGL sub-sets required for any particular version of AE at Adobe’s site, so I’m afraid it is a buy-and-pray situation unless someone can provide the OpenGl sub-sets required for your version of AE such that you can check them against your gfx card and its driver.

Sub-sets aside, you can nevertheless check whether your gfx card and its driver are using OpenGL 2.0 which would be a must for more recent versions of AE. To check your version of OpenGL (Windows or Mac) use this Tool at –
