Hi Michael.

Good morning.

@You : "...It's shaded surface anti-aliasing that you want there. I think that could be possible to add as an option for v4..."

Yes! It would be very desirable to have that feature. Thanks.

@You : "...I think I've got it worked out how to speed up shaded surface rendering when there's a lot of VRAM available but I haven't yet got it worked out for curves yet..."

Ok. This is good.

@You : "...Not for a limited size model like you've got there but if you increase the model complexity a lot more then it's a different case..."

Yes, you're right. But for very, very complex assembly or model you can always play with the Mesh Angle option.
Please consider that actually, on my laptop with a almost outdated Quadro K3100M with 4GB Ram, I always use a Mesh Angle of 5 without any speed problem also for a (not simple) model like this one (the model it's not mine).
And with my Gtx 1080 Ti I can easily copy and paste the same model many times to have no noticeable speed issue.
Nothing that really impact the modelling process.



I stay tuned.

Have a nice day.
