I am having problems with buffering in FL Studio! When I use a few VST;'s the buffering is that bad on playback that I can't even hardly hear anything for the popping / crackling etc!!

I have adjusted the buffer level in the 'Audio Settings' but that hasn't made much difference.

I know that it has something to do with CPU usage, but I haven't a clue what to do about it!

Will it make any difference if I upgrade to more RAM??? Or do I possibly need to upgrade my processor????

Any help would be greatly apreciated.

Thanks in advance!
