DXVK 0.80 is out with a new cache to reduce stutter and further CPU overhead improvements

YoRHa-2BThe game is silly and
a) creates multiple D3D11 devices
b) changes its current working directory multiple times.

The actual cache file you're looking for is in the /bin subdir, not in /bin/x64.

Also, Witcher 3 does not compile its shaders ahead of time, so you will still encounter stutters in this game (although it should be less annoying because it can now use multiple threads to do it in parallel).

Good to know, thanks. I see the one in bin, and it's around 1 MB after a brief test.

I noticed that general stutter is lower now. A lot of Ryzen cores help (DXVK reports using 12 threads for compilation):

Yes.

If you have 8 cores ( 4c / 8t included ) and greater , it uses 3/4 of cores for that.


If you have less than 8 cores it uses half of them.

I just get more impressed with this project with every release. The game I can see the most difference in from one release to another is Super Mega Baseball. With just the regular Proton beta it ran but very slowly even when shadows and crowd density were set to minimum. Then after updating the dxck in proton to .072 and using nvidia beta drivers I could play with max shadow quality and max crowd density. After adding .80 to Proton I can now add 8x AF and the game is still running great.

LeopardThere is no need for seeking meaning in numbers.

Just enjoy it , that's what i do.

That might be true in this case; though in general (including anything mission critical), you do have to think twice, or take precautions, before using zero-point software.

ShmerlI tested it with The Witcher 3, and somehow witcher3.dxvk-cache that was generated is just 12 bytes.

Fantastic update, this has eliminated a lot of the stutter in Witcher 3 :-)

I have but one question - How does the new shader cache work with Nvidia? The games now seem to store shader cache in both the *.dxvk-cache file and Nvidia's own method (I'm using the __GL_SHADER_DISK_CACHE_PATH envvar). Do they work together or I can disable the Nvidia built in one?

Thanks for your work.

The new DXVK cache stores pipeline state, while Nvidia's cache stores compiled shaders. There's no actual overlap.

That clears it, thanks :-)

F.UltraSo I take it that DXVK is now DX11 feature complete, this is incredible news!

Not quite, Stream Output is still a big feature that's missing.

Ok so that is not part of the feature level then I suppose? (Or the Wikipedia page is wrong on 11_1 being the highest feature level for DX11).

Anyway, you are far to humble ;)

It's part of 10_0 and above, but DXVK currently just ignores that and pretends that everything is fine.

And, well, that works in games that don't need the feature, but some do need it.
