SL360 Custom stage size, anyone working in 1080 or 4K?

Higher resolutions significantly affect performance of most Articulate Apps - Storyline more than the others.

Normally I would view development in 4K as overkill, but I see why you would want to do something like that on a 75" device.

Not much of an alternative in this case, what you're experiencing is ordinary behavior, unfortunately.

Good luck.

Note: For what it's worth there's significantly less of a hit during playback of the actual output, so maybe enduring the lag during development may be worth it in this case.

i have just started building in 1080 and I've not experienced any problems at all so far.  I wouldn't say its any slower or any faster than normal.  I would think though that 4K is probably a bit overkill and probably would affect the performance a bit.

Has this changed anything since the 2 years that gone by? 
Is the performance or stability any better? Not from my tests..

Anyone else tested?

I have since gotten a lot better performance  computer - so the tests have shown that capability of SL is about the application coding not only the computer performance, although it does help with a lot more memory in the machine. 
But i wouldn't say that SL currently is optimized for 4K content.
Larger projects is unresponsive.
