Testing new Mesa ACO shader compiler for AMD
Page: «3/9»

Quoting: sr_ls_boyWhat mesa version is this ACO shader compiler forked from. Is it 19.1.X or the unreleased 19.2?
Doing comparisons against the wrong mesa version won't mean anything.

They probably rebase it on Mesa master periodically. But you can compare it to itself. I.e. simply disable ACO using environment variable, and it will use the default llvm path:

RADV_PERFTEST=llvm

So no need to build stock Mesa separately for testing.

Short test of Rise of the Tomb Raider with Proton, Very High settings:

Average FPS, LLVM > ACO
Spine of the Mountain: 84.1 > 88.8
Prophets Tomb: 66.0 > 67.4
Geothermal Valley: 65.1 > 66.4

And here are the frametimes (all three tests combined):

Clearly better frametimes for ACO.

How did you build the graph? And did you collect the data using Mesa Vulkan overlay log?

Curious, the last tag in the ACO repository is:
Date: Mon Jan 29 11:27:18 2018 +0000
Update version to 18.0.0-rc3

The developer must have been working on this for a while. They have
mesa's commits but none of the tags.

The game itself dumps the frametimes in a folder. The graph is built with gnumeric.

They must have been working on it for a while. Making a compiler takes time.

According to the announcement on the Mesa mailing list, "a little over one year". That's actually not that long considering the size of the team and the nature of the project.

Yeah, though it's not ready to be merged yet, it's in good shape to be tested.

So far, I haven't found a title that Mesa/ACO has a problem with.
I once was able to run 'Outlast 2' but it won't work anymore and I
don't know way. I'll keep looking.
