performance
my version is 1.13.02
i've got performance problem - the vectorization is too slow.
i can't use gsmodel beacuse i often switch layers (and must invalidate all then) so i use wingdi.gs. i use release dlls too.
in my case the quality is not so important as performance.
i set facetres parametr to low value.
i thought about hiding small elements, but i don't know if the engine supports it.
how can i improve performance?

1) did you try winopengl.gs, windirectx.gs? they can work even with gsmodel turned off.
2) what do you mean by "switch layers"? are you set them on/off? are you change color, etc? are you set them frozen/thaw?
sincerely yours,

michal,
i read your previous post, and now i understand your problem.
the problem is our gsmodel doesn't take into account on/off layers. if you switch layer on/off, you have to regenerate model. i think, it is mostly defect of our model implementation, and it probably will be fixed.
you can fix it on your side this way. you can implement your own software metafile in a manner like it is done in windirectx device (see exgidirectxgeometry.h). each metafile's record (or, depending on task, each metafile) should store layer id. when playing metafile there must be check - is layer on or off. to implement this check, some kind of map or hash table storing off layers will be necessary.
sincerely yours,
george udov

is it fixed in version 1.14?

unfortunately, it isn't.

invalidate gsmodel after background color change?
if using gsmodel, should i invalidate the gsmodel when the background color changes and the new background color results in a different palette (light vs dark) then was set previously?
for example, let's say that i am displaying a dwg file and in my application, i currently have the background set to white. now, the user changes the background color to black. in order to get the "correct" display results, must i invalidate the gsmodel?
by "correct" display results, i mean that i want to get the correct colors that are "background-specific" for color indexes whose rgb value is different between the dark and light palettes.
does my question make sense?

yes, you must.
