I need to draw lines in my program, but dbLine is soooooo sloooooooooooow... what can I use as an alternative?

I'm wanting to draw lines for mini particles. They're not going to be big enough to constitute using an image, and they'll be variable in length, hence why I want to draw a line for them.

While we're on the topic, does anyone know why DGDK's 2D commands are so slow? Drawing 40 lines (each being just a few pixels long) per frame with NO OTHER PROCESSING brings the framerate down to roughly 14 fps! I have a monster computer, this should not be happening!

Still open to suggestions for alternatives.

Check this out, let us know if it works and how much faster it is.

I remember using that for 3D lines in DBP, didn't know he made one for DGDK.

I installed it, but got a linker error saying it couldn't find libcp.lib. Did a search around and found a few suggestions to just add the library to the ignore list since it had been depricated, but doing that only caused an access violation error at runtime when a particle attempted to draw (using the d3dLine function)

Any ideas?


I've gotten a fairly nice looking particle by pasting a stretched image, but I bet I could get even smoother looking particles (and higher framerate) using the gradient effects of the D3DFunc library. Pasting images (for whatever reason) runs faster than drawing a line. Why is that? Isn't a line easier to draw and less processor intensive than pasting an image?

Make sure you ignore all of these libraries:
libcmtd, msvcrt, atls, msvcprt, libcp

Then make sure you have your code generation set to /MT

Then it should work.

EDIT:
Actually, make sure you call d3dInit() before you do anything.
