Survey: Does anyone experience significant lag with V-Ray IPR renders?

[RobH2]

I've had significant lag with V-Ray IPR renders the past few releases of Max. I've posted at Chaos Group and until now they have just waved past my posts and said they have heard of no issues. 

They responded to a new post of mine so I have their attention briefly and they asked for the posts here where we discuss it. Unfortunately, those discussions were within other topics as we drifed off-topic, so I haven't been able to find them. 

I'm posting again to see if I can find other users who have found that IPR renders are now laggy and slow compared to how buttery smooth they used to be. Anyone else frustrated by how sluggish IPR is and how is cripples Max overall while running?

What processor and OS do you have?

Has anyone experienced severe lags when running multiple monitors? I'm just trying to zero in on my issue. I have horrible lag running V-Ray IPR on multple monitors. It's better if everything is on one monitor but still laggy.
