My laptop is several years old now (2.2ghz and 4G ram) and I am having concerns that it is not adequate for vixen 3. I have created a couple of sequences now and noticed that the preview play back was not as smooth as I was hoping. Now I have all the hardware set up it is the same for the actual lights. Although my sequences are very basic (fairy lights only) it still isn't as tight as it should be. So my question is, should I give up on vixen 3 (which is great otherwise) or can I make it work with different settings etc. Other options would also be appreciated. Thanks.
