Thanks for helping!
Sorry I forgot to post my specs:
Windows 7 64bit
Intel i7 Q720 1.6GHz
GeForce GT 330M v187.83- I know that my video card is not supported.
Video playback is set to software only as I do not have the option to change it. Playback is great, very smooth. It is only when I am making edits that the system locks up for a few seconds. I didn't have any problems with CS4, so I am just wondering if it is the fact that CS5 requires better hardware or is there something I can do to make it run smoother. Thanks again.
Im not sure how much RAM your card has but if it has 1GB then you can apply the cuda hack and turn on the MPE option.
Here is a link to do it.
This person shows using the 330M on his page.
Its just adding the name of your card to the supported list text file.
Worked perfectly, thank you!
Glad that worked for you.
If you want to test your system and see how it stacks up to others you can take the PPMB5 benchmark test for Premiere.
You can see others results on the results page.
