MLAA For Mesa Is Ready For Testing

[smitty3268]

Using renderer: OpenGL 2.1
Gallium 0.4 on llvmpipe: VMware, Inc.

You're running the software renderer there, instead of the r300g driver.

that output is obviously wrong.

Beside this error: I'm wondering if the FPS output with the sphere is really right, but the sphere shows more FPS if the window is in the lower right corner (~600FPS). In the upper left corner I get ~250FPS. Both without MLAA. With MLAA it's ~77FPS and ~74FPS so it's not that visible but still the case.

Window position anomaly - maybe caused by your compositor?

Timing wrong - possibly. Could also be that you use a newer irrlicht, as the title bar fps is taken from irr.

[curaga]

So...this MLAA is entirely in software/shader, and not actual GPU anti-aliasing method?

Yeah. But it's entirely on the GPU, no CPU software part.

I'm also getting some really odd numbers with the latest version of the test, and this is using the binaries you provided.

Ops, good catch. Hopefully that explains the really broken display too. So next up is diagnosing why it didn't go with r300g. Sorry for all the noise.

[curaga]

Okay, trying again. It's funny how llvmpipe gave me correct numbers with the previous commit; let's see if the latest improves things on real hw.

[whizse]

Yeah, the new results seems to be okay:

Ran 41.635s, average fps 288.01, min 1

Average on fps 130.86, average off fps 583.15

(The first test I ran was with power_profile set to low, so quite far off the mark, sorry about that!)

[curaga]

No, it was interesting to see how much the low profile affected the performance. Almost exactly four times worse with low.

You were right, it was KWins fault. The average FPS is now also correct with the new version.

Results with r600g and hd5770 (juniper):

low: Average on fps 60.43, average off fps 312.62
high: Average on fps 60.38, average off fps 526.58

with MLAA on, the FPS was somehow capped at 60FPS. That's probably because SwappbuffersWait is turned on, but why isn't the FPS capped without MLAA?
