Found solution for freeze/lag on UI when IR running

[Lomarx]

Hi all,
I had problems (freeze/lags) with 3ds max 2018 UI when IR running, for example when open material editor or simply open quad menu with right mouse button.
For those people that have the same problems, i've found a solution while reading this post on chaosgroup forum:

I've added this environment variable: QT_OPENGL set to "angle", and now I have any kind of freeze or lag when IR running
I hope this is useful

watching this thread closely. I'm a bit disappointed in software performance lately. But given the fact all these amazing renders can even be created, especially when working interactively in 4k, there's bound to be some speed bumps to go through. Thanks for sharing
