Previewer slow/lag

Hi all,

I am new to Construct 2. I am excited and working my way through tutorials. While working through tutorials I've run into previewer troubles - the previewer becomes gummed up with extreme lag.

My first tutorial (Beginner's guide to Construct 2) started fine, then, in between switching from creating an event and testing that event I noticed the previewer started to slow down drastically, almost to a complete halt. I researched the forums and found the "trouble shooting construct 2's preview server" topic and discovered the problem at the time to be my browser. I switched from internet Explorer to Chrome and it resolved the problem.

I've started my second tutorial (How to make a platform game). I progressed to "adding an enemy", selected the "run layout" to preview the game and the lag came back. I checked my browser to make sure it was still Chrome (it was).

I've now gone through the list of "troubleshooting construct 2's preview server". I've also read through several other forums about dealing with chrome directly. Ex. tried Firefox, checked firewall, changed port etc.

No success.

Any help is greatly appreciated! I'm excited to get past this hiccup and carry on with fun stuff!

My specs if needed:

macbook pro retina

64 bit windows 7 via parallels (I run cad programs with success)

16 gb ram, 4gb dedicated to parallels

2.6 GHz intel i7

google chrome

java version 7, update 45

I guess CAD-programs, as mostly vector-based programs are not good to compare. PLS correct me, if i?m wrong. Did you ever render something using parallels? Like a movie or a 3D-model with ligt added etc?

I guess parallels is always a pretty bad thing. I would highly recommend to make an own partition using bootcamp. Makes everything a lot more stable. :)

Did you ever try another preview browser? Perhaps it?s an ie and chrome-based problem.

Safari works pretty good for me :)

Good luck!

Is it also launching Chrome within Parallels? VMs sometimes have pretty poor performance, since they don't support GPU acceleration and will give you software rendering. Maybe previewing from Chrome running back in OS X will work? If not, maybe using preview-over-LAN mode?
