I have recently reverted back from SR13 to SR12 and the display got very very slow. I investigated for a while and found that it is mesh wires on a slightly denser meshes that cause the slowdown. Surfaces/polysurfaces with tons of edges are fine, dense meshes with no edges visible are fine, but meshes with edges slow down to a crawl/unusability. I wend back to SR13 and it is the same - something must have gone wrong during the reinstall, even though all options, settings and customizations were preserved. OpenGL tessellation is ON, Running is Safe Mode doesn’t solve anything.
@stevebaer - would you have any ideas/suggestions how to fix it? I was trying to avoid minor problem with SR13 (materials bug) by reverting back and now I made the whole Rhino unusable, no matter what SR I use.
Need to work in V5 for now that works just fine, but can’t in a long run. Hope for some ideas how to fix this!
