1. This should fix Issue 1625 (Bizarre Auto Frame Limit)

Browse Source 
Now the frame limiter yields on CPU thread, not as before on GPU thread mistakenly

2. Fixed clear of VI interrupts
   I guess VI interrupts are not used at all, because they were never cleared before

3. Made GPU thread 0% processor usage when paused whatever your active config is.
   I tried the event approach but somehow the thread resume latency is excessively long (Who can tell me why?)
