If you want to tessellate a whole model it does take some time. But I don't want to spend time processing the Real-time render in the background too.
You can save a Little time by pausing first, then starting. But it will unpause in the middle of it. After you change the tessellation once, it unpauses.
Can we just have control over it staying paused or not pausing? I'm trying to speed up my workflow while I wait for a faster machine, which I'm sure our machine replacement will be a bit delayed now.
