Adobe After Effect CS4 was not recognize my ATI HD4850 Graphic ... but then problem solved

I was messing with the Cartoon plugin in Adobe After Effect CS4 which utility the GPU capability. It didn't work on my machine as the rendering was ultra slow. When I opened preference. it said that "OpenGL Not Found". But when I went to Adobe site, it stated clearly that my card (ATI HD4850) is one of the supported card.

So I updated my After Effect from 9.0 to 9.0.1. I also update the driver to ATI Catalyst version 8.12, which is far higher than the required 8.8 stated on the Adobe well page. Well, the After Effect perference still says OpenGL Not Found.

Being fustrated, I opened Photoshop CS4, as I remembered that Photoshop CS4 also support GPU. The perference in Photoshop CS4 found the GPU, stated the ATI 4850.

Here's the strange thing: I then opened Adobe After Effect CS4 again and BOOM! This time AFter Effect saw the GPU and allow me to check the OpenGL checkbox. Once checked, everything goes awesome. The render of Cartoon effect is now instantly. Pretty sweet.

Well ... at least it works now.
