> AVG antivirus running, Microsoft security essentials and other regular background programs...
Try turning off all of these programs that aren't essential for your work.
Some antivirus software works by checking every read and write operation, which can immensely slow down work in After Effects (and other applications).
I agree with Todd. Make your security tools behave. That doesn't mean to turn them off completely, but at least make them keep their fingers off files when writing them (major performance hit!) and not running active scans while the CPU is busy. Letting them scan on file read is usually no problem, but if you use AE's cache and it's under their surveillance due to the sheer number of files it may also show a loss of performance...
Thanks you for your response. I have turn off the "Resident Scanner" on Avg but I have not seen any improvement. I also notice that my desktop AVG resident sacnner setting have a exception showing my extra HDs excempt from scans ..i will try that in my laptop. Also do you think my setting need tweaking?
Thanks for your help.
There are a lot of things that can affect performance. Many are listed on this page:
They range from updating drivers, installing updates, and defragmenting your hard disks to making tweaks specific to After Effects settings. It's nearly impossible to give specific advice for the last category until we're sure that all of the former ones are taken care of.
Ok im think im still confused.. Rendering of object and RAM preview etc.
. i can understand if i click on play and things dont play at the right frame rate..but shouldn't I be able to reposition/scale the elements of your composition without lag? I honestly dont see why the program needs so many resources to place objects around... like i said my projects render perfectly. Imagine this.. what if you were putting together a jigsaw puzzle and every time you position a piece it will take 10 seconds to happen..you get me?
ANyway thank you for all your help.. i will probably uninstall CS4 from my laptop and install CS3 on it... the onl;y thing i will miss is Adobe Media Encoder which is very usefull.
Thaks you again.
If it still lags, you are having a driver confligt somewhere. This can be anything from graphics card to tablets. I suspect that some config in your graphics is set in a way that prevents AE (or possibly even otehr Adobe programs) from refreshing the screen. if you are using a specific setup, try to reset to factory defaults and see if it helps any. If you use dual screens, try to run with just one screen as a test...
