Just letting you know, I love the performance increase in 2.2.4! Runs just as well as 1.5.4 does. Well done! I would've posted on the forum but my account seems to be gone again.
Really nice to know. Thank you for the feedback. dgud says it should get better when they (björng and he) finish the new code which will add concurrency for the Wings3D's core. They believe it will handle dense meshes better than it does nowadays.
