Hi again, thanks for such a quick reply!
1. Yes, I am using Atoms on all my players, but problem appears only on Win7-based machines. I've been thoroughly analyzing the stress of the CPU in both 720p and 1080p signage campaigns - its usage never exceeded 30-40% (at the moment I'm mostly using the dual-core D520 model) so I think we're pretty safe to assume that it is not the CPU issue.
2. I'm basing on H.264 video spots on my campaigns (and a few "widgets" from SignageStudio, such as Weather, RSS and HTML embed), but also have only one personally-made swf - a short, looping bitmap animation. How can I check if any of my campaign's elements are making a memory leak?
3. I've set it to 1.5 Giga while having 2.0 Giga - should I set it to a higher value?
Best regards!
