Improve viewport performance

[Stirling]

After buying a new system -Threadripper 5975- and sticking, for the time being, with the 2080ti that I already had I'm now desperate to work out if there's a way to improve viewpoint performance in Max.

The moment a scene gets even vaguely heavy, panning around in the viewport becomes painfully slow and unusable at times and is at its worst when I've imported contour lines from CAD drawings (though often with Forest Pack heavy scenes too). Now I've read from various sources that it's best to tidy these splines up in CAD before importing but the problem with that is that I need the detail in the contours. In Max, the moment that I convert the contour lines into a terrain the viewport performance improves so it's definitely struggling with large numbers of splines.

Will a gfx card upgrade help this at all or is there a setting I've missed that would improve things? I've been toying with the idea of a 4090 but it seems pointless if it doesn't improve viewport performance given that I mainly CPU render.

Max struggles with lots of objects. What I do when importing a CAD plan is import it as one object, and detach splines when necessary. The less objects you have in Max the better. That will drastically improve viewport performance. I try to keep the maximum amount of objects to 1000. Also pointclouds in forest pack immensely slows down my performance as well, that's why I try to put everything as piramid proxies or similar when I'm done working on it. I also only work in flat color, no shading or whatnot. There's a few more options but I don't know them by heart when it comes down to showing materials in the viewport. One that I also disable is the minimum framerate. I put this on 0 (disable) because the constant popping in and out of bounding boxes of objects is just simply annoying.

the thing with the framerate is interesting...

I also convert everything into EditPolys. Or set an editPoly on top of the Bodyobjects. But be careful: I newly recognized bad rendering issues on such objects. So if you are sure you won't alter the Bodyobjects anyway, re-import them as OBJ´s for instance and everything is fine. I also weld vertices as much as possible.

But in the end, I never got "wow" effect when getting a new Graphiccard. Thats really simply because Max still sits on it´s stupid old workspace system. So i am still sticky with my 1070 GTX =) ( ok, more ram than 8GB sometime would be nice...)
