vray hdri map viewport display

[OPEN_RANGE]

When setting up hdri for exterior lighting. I start with Vray HDRI map in Mat Editor. Set spherical mapping and instance into max environment. Then config viewport background to show environment. So far so good. When I adjust horizontal rotation to position the HDI it works but the performance is painfully slow. Lot's of lag, difficult to work with. If I click the rotation spinner once it takes about 4 seconds for the HDRI to move in the viewport. In tutorials I have watched this is done and the rotation is very smooth and instantaneous in the viewport. I have a decent video card and lots of ram. Can I change some setting to help this perform better? Do others have this same slow HDRI in viewport issue?

I haven't had to do this for a while, over a month, but yes, I had this exact same issue - too busy at the time to determine what was the cause, and thought it could have been due to an updated NVidia driver.

Was in 3ds Max 2017 and V-Ray 3.60.04.

just the way it is, I guess. I posted this on the AD forum last week. The only reply was to use MAX's sky system - duh, but I don't want to. I turn the environment off when I rotate.

OK thanks to you both. It's helpful to know that it's not just a problem for me /my system. The various video tutorials show it rotating very smoothly. Including the one below:

I think I have had that same smooth control in the past. Now....not so good.

Yeah, but not since MAX 2016.

I'm getting this exact same problem in 2018 now. You guy's still experiencing this issue?

Lock HDRI to texture is a work around.

Just rotate Domelight instead, although you cannot line up to a vray sun using this method.

Problem remains in 2018
