Few weeks ago I posted to ask Which type of Video Card accelerate glLineStipple function.
None answered me. Someone give me appreciated suggestions to substitute this function in that cards(nvidia) didn’t implement it.
I discovered this:
ALL Nvidia CARDs (Consumer and Professional Quadro series!) DON’T accelerate this function.
ATI Radeon 7500 Ati Radeon 8500, FireGL2/4 (IBM chip), ALL wildcat Videocard series accelerate this function.
ALL CAD software use line stippling and then all CAD users that use a project with stippled lines can note terrible performance with Nvidia CArds.
With Specviewperf, enabling -lp (-linestipple) option, all can note the difference of performance between Nvidia and other OpenGL cards.
I know that this, for Videogame programmers is not felt as a ploblem, but the others? is it possible that is this only my problem?
Developping an OpenGL engine I cannot ignore Nvidia (that onestly has very good drivers) then…
Does Nvidia resolve this problem in their Future Chips ?(because I think this is not a driver problem but Hardware).
Does Nvidia feel this as a problem to solve?
Someone tried to suggest using 1D Texture instead, but in my experience I’ve seen it is not usable to substitute glLineStipple function.
