It's a performance issue not a crash so updating C++ won't be necessary.
Delays etc won't be down to antivirus. I do not recommend turning them off rather configuring them to exclude certain folders and processes. However you could turn it off temporily to see if it makes a difference.
> I'm using an ADK laptop ( the 8600HW, NVDIA Geforce mobile, tailored and tweaked for audio) What is your specific graphics card? Looking it up you have nVidia GTX860/870/880 graphics card options:
You can downloading the latest graphics card drivers here:
http://www.nvidia.co.uk/Download/index.aspx?lang=en-uk You will probably want to look into download the latest Intel software:
http://www.intel.com/p/en_US/support/detect ... and BIOS for your laptop (from ADK) if you haven't already....
Run all the Windows updates as well, check out most of the optional updates as well...
We still need to know the
exact make and model of your sound interface. You should be looking at updating to the latest drivers and firmware for this device.
If the probem persists after this we would then be looking at X3. If you are going to ring up Cakewalk I would handle the above first before you ring them. I really would try ruling everything out before you contact them, they would be giving advice similar to this first time around.
(BTW it may be running well in 8.5.3 and not in X3, but this doesn't rule out anything as we are dealing with software dependencies here, therefore you are not comparing eggs with eggs. ).
Oh and rip out that dongle to see if it makes a difference.
Cheers...
