Aerodrums and Aered forums

Hi
I have a Core 2 duo 2.93Hz with integrated Graphical card. I run in 8.1 64 bit.
I can use Aerodrums for a few minutes (the framerate is 126 something, green) and then it hangs.
Would it help with a separate graphical card?
How to troubleshoot the cause?
Thank in advance.

Sorry I hadn't read this message when replying to the other one. Could you give me your computer's brand and model number, and the brand and model of your integrated graphics card? Also, how much RAM does your computer have?

Getting a good framerate that drops after a while could indicate a memory issue. Do you get the problem with the "My first Aerodrums kit"?

If so could you do the following experiment: go in Drum kits, select My first Aerodrums kit, click the Clone button. In the right most list on the screen that appears, select the Hi-hat and press the < button to remove it from the kit. Then click Ok, select the new kit and click Ok again, then click Drum. Do you then get a stable framerate around 125?
