Re: gEDA-user: PCB+GL Progress



As promised, here is the data of my home desktop. I is one of those 
Computers that receive a hardware upgrade every now and then. The last 
change was a decent graphics card. I deliberately chose the agp fastest 
available at my local dealer (nvidia GeForce 7600 GT, 512 MB). 

Like the other desktop, polygons seem to be the major contribution to 
sluggishness. If top and bottom bpolygons are visible, redraw rate drops 
to a mere 2.5 . For some reason the top polygons are worse than bottom 
polygons. If I disable the top polygons and display everything else,, I 
get 17.5 redraws/sec.

This set-up is sensitive to zooming in. I get redraw rates as high as 450 
when zoomed in and polyons not displayed. If the whole pcb is in viewport 
and polygons off, I get 39 redraws/sev.
