Please correct me if I am wrong , Linux has HRTs introduced just to solve this problem right ? Windows doesnt have anything like that ?

How is micro-sleep solving the problem that OP has underlined ? >The resulting behaviour appears to be that the message queues are filling up, and as a result, not only the windows themselves are becoming unresponsive, but the system as a whole is starting to respond poorly. This seems to happen even on a quadcore system with HyperThreading, which should be able to handle 8 threads simultaneously. So just having enough cores is not always the answer, apparently.

Yes, I posted a followup which investigates the issue somewhat further. It appears to be some bug with the message queue handling, specifically when the UI is in Aero mode. In classic mode, the problem is not there. In Windows XP, the problem is also not there. https://scalibq.wordpress.com/2012/03/28/the-story-of-micros...
