Adaptive sub-d

Hello everyone, I have one question. Does adaptive subdivision work for everyone? I have two computers, one core i9 10900f with RTX 4070ti and a second one with 10400f and rtx 3060ti GDDR6x memory. And when I use adaptive sub-d, the blender either crashes or is just very slow. Regardless of the size of the scene..

    No problems whatsoever, I have an i9-13900KF and RTX4090...

    But with your specs, you shouldn't have any problems either.

    Are you using 4.2.2? And what size of the Scene are you talking about: does this happen with only a Default Cube already?

    Yeah i was going to say, regardless of the size of the scene meaning even with the default start up file with the default cube? If that's the case maybe try updating a bunch of stuff on that computer, video card drivers, downloading a fresh new Blender, updating windows or Mac, etc. See if that helps.

    no matter what size the scene in blender is at all. This means even the simplest cube. The only problem is with the adaptive sub-d. When I start applying any material with displacement. System win 11 blender. 3.6 3.5 4.2 4.1. I have a thought that this is a problem with the video card drivers and some kind of conflict with window 11

    Yeah, GPU driver is high on the suspects list...

    It's a bit strange, that it's happening on both computers...but that also, more or less rules out a Hardware issue on your side (luckily!).

    Perhaps you are setting the subdivision to have way too much subdivisions and it is crashing it all? So also start by setting things to not so many subdivisions and start dialing it to have each time more and more geometry and subdivision and see where it chokes and crashes. That could be a troubleshooting strategy as well.
