MLAA For Mesa Is Ready For Testing

[curaga]

The test app sets vblank_mode to 0 to avoid vsync. Swapbufferswait can't be overridden from the app though.

Yeah, I was wondering why it didn't cause the sphere to run at 60FPS without MLAA.

Results without SwapbuffersWait:
low: Average on fps 86.40, average off fps 811.24
high: Average on fps 162.36, average off fps 1540.74

Some more data points:

RV570 / r300g
Ran 60.835s, average fps 360.19, min 1

Average on fps 181.47, average off fps 574.93

G45/Eaglelake / i965
Ran 112.156s, average fps 79.93, min 1

Average on fps 20.30, average off fps 199.95

MLAA isn't rendering correctly with i965 as seen on this screenshot: (ignore the tearing)

Not sure if it's of any interest, I guess you're targeting G3D-drivers?

[curaga]

Yeah, inside Mesa it's gallium only. But if i965 claims to support the required extensions, you might want to report the bug.

Thanks for the testing whizse

Does not seem to do anything on mine image quality wise (I guess it's that shader warning up there). No visible image distortion/artifacts.

I think that GL_ARB_shader_texture_lod is only available on SM 3.0 (r500) cards and higher.

Still reporting MLAA as being off, and still jagged edges.

This is with the latest git master mesa, on an X1400 (r500). I'm using KDE4, and turning composting on/off doesn't change the result.

You can toggle MLAA with pressing 'm' on your keyboard

Yeah, the minimum hw is r500/gf6. Not sure what's the minimum on intel.

Thanks, with MLAA I get good output (including smoothing) and 20fps. KDE feels really sluggish while it's on and I get a warning that desktop effects are being disabled due to bad performance, but CPU utilization is low.
