Why is paste so slow?

In Rhino 6, pasting geometry is a little slow, but in the WIP it is super slow. In Rhino 5, it’s instant. What’s going on?

In the WIP, copy w/InPlace is instant, and so is dragging a copy using the gumball holding ALT, but using the windows clipboard is where it’s super-slow. It takes literally 4 seconds to paste a cube in Rhino 7.

I have ‘allow copy and paste to version 6’ turned off (it’s even a little slower with it on.)

Do you have any large textures or picture objects in your file?

No, this is just with freshly-opened rhino and the object in this example is a simple cube.

Hmm, I guess we need to look at plug-ins or other possible sources of the problem then… Can you run SystemInfo in Rhino and copy/paste the results here?

I’ve tracked it down to OpenGL, so I’m looking into how to fix it.

Well, I updated drivers, etc, but no luck. If I change Display Pipeline Assignment to Windows, then it works perfectly, but when I use Open GL, no luck.

I would update the Intel driver as well, or, as others have suggested, disable the onboard Intel graphics card completely. If that improves things, that’s it…

I disabled the Intel graphics, but no improvement.

Ouch - OK - someone else will have to chime in here… @pascal ?

Hi Peter - I also see a noticeable lag on Paste in V7 - one second or so, here -, a very slight one in V6… and none in V5.
My wild ass guess of the moment is that the extra in V7 may be related to the extra copy/paste capabilities added to V7 - you can paste to Illustrator for example - @stevebaer - is that possible, that the new stuff is taking time?

-Pascal

Very doubtful, but anything is possible. We won’t really know the cause until a developer can repeat the lag in a debug build of Rhino

Yeah, plus, I also see it is instant in V7 if I set the display to use Windows.

Thanks, I’m so glad you can see the problem, too.

I do experience it as well, even the most simple elements like single curve or face. Latest WiP build.

Yep noticed this here too, glad someone wrote in about it and McNeel might work on it. It doesn’t matter if it’s a lot of information or just one line still takes a while.
