New puzzle format

It will be optional. It's still in development, we're just using the tactics trainer as the testing platform.
I'm running chrome 35 on a i7 macbook pro retina.

What I meant by responsiveness was mostly the drag and drop visualization. I really like holding a piece over a square while I wait for an opponent to move, or dragging/dropping the piece off the edge of the board to deselect it.
@georgeglue

You're running a pretty similar set up to me on a retina MBP. The issue here cannot be optimised any further as the same amount of lag can be experienced on the current Play chessboard interface.

Here's the chessboard interface that we used previously, and from my testing the lag is the same. http://chessboardjs.com/examples#5000

The core issue is that the res of the macbook's screen is too high. If you're running the display in scaled mode (i.e. the More Space option in your Display Preferences) you should try lowering the res. I'm effectively running my display at 3360x2100 which seems to be the source of this lag.
@Clarkey it looks like my setup is fairly similar to yours, but I always put down any apparent lag or anything like it to being on the other side of the planet. That's usually a good explanation.
The new tactics trainer doesn't work for me, using Firefox (iceweasel) 33 on debian. It works in chromium though.

I can't move any pieces. When I click and drag and so forth the chessboard is completely unresponsive.
That's interesting, FinkelFrand. Works fine on my firefox 32 on archlinux here. Let's see if we can find what the problem is.

Can you open your firefox developer tools (Ctrl+Shift+i) and run this in the console:

'transform' in document.body.style

does it return true or false?
also, can you play by clicking on the piece, then on the destination - as opposed as dragging the piece?
> 'transform' in document.body.style

It returns true.

> also, can you play by clicking on the piece, then on the destination - as opposed as dragging the piece?

Nope. I don't see any animation either on the board
Thanks for your help. Unfortunately I'm still not getting what the issue could be. Didn't you see any error in the console while trying to use the training? You use debian so I hope you know your way with computers - maybe you can dig into this issue a bit? I sure wish I could reproduce it, but I can't :(
Alternatively we could set up a teamviewer so I can debug it directly on your machine, if you're up to it.
I don't use teamviewer, I could setup a vnc server with x11vnc but I think I need to portforward the router but I can't log in to it (it forgets passwords or something) and I don't want to reset it right now. I'll try to figure it out but the chances are low as I don't understand how it works.
