Thanks for the reply .

Sure I’ve been seeing this sentiment all over the place but I was trying to get to the bottom of how bad it actually is .

From my experience so far it seems to have failed at the first hurdle due to not being able to correctly draw footage that has come straight into the comp with no effects or scaling etc . Is this what most people get ?

Hey Guys

I wanted to ask if you guys would please clarify that the quality of OpenGL rendering not being as good as software is a known issue ?

I am finding that in a project I am currently working on and wanting to test how much faster OpenGL was (which it was) but the source footage which is a 1280×720 .png sequence in a comp the same size and set to square pixels and has no effects applied to it is appearing noticeably more blocky/pixelated than with OpenGL disabled .

As an interesting test I provided AE with the same sequence that was 2048×2048 (power of 2) and the result is better but softer but still not as defined as the original source being rendered without OpenGL .

I have the latest card drivers and although nvidia says that they now support OpenGL 3, AE CS4 which I am currently running is only showing as using version 2.1 . This is on a Windows 7 x64 platform is that makes any difference in this case .
