polygon smoothing
Post: #16
FSAA is a terrible solution for ANY 2D app, because:
1) the quality is worse than the old hardware smoothing
2) requires much more VRAM / fillrate
3) isn't as flexible (can't mix aliased and antialiased primitives)
For 3D apps FSAA probably seems like an OK solution since you generally want to avoid sorting your scene back-to-front to get correct alpha draw order. But it still is a big waste of time/space for a small quality improvement.

ATI's drivers suck. Just buy an nVidia card. There, problem solved.

Besides which, even if my personal system is OpenGL-compliant, what about my customers who bought machines with ATI chips? Eh!?

okay, sorry, next time I'm being sarcastic I'll make sure and be as discreet as possible so as to kill anyone with over obviousness.

ever thought of changing the polygon fill mode to draw them antialiased lines rather than drawing GL_LINES?

You need to check again. The 12" Powerbook has a Nvidia 5200 GPU

Yes, I thought of that. The current Radeon 9x00 drivers don't support point or line antialiasing either.
Line antialiasing is unreliable in any case-- the G4FMX can only draw lines 1px wide, for example. And the Radeon 9x00 doesn't draw anything if the width is < 1.0, which is out of spec.
In the past I've replaced both points and lines with textured quads, but now quads are broken as well. I started another thread about this earlier.

Whoops. Still stating the truth that their is a Nvida GPU laptop just in case no one knew that.
