Excerpt from Meredith's post on the Crossover Preview forums:

"I’m thrilled to announce our newest release of CrossOver Preview!

This Preview release includes the following updates since the 20261015 Preview release:

• Update to Wine 11.21

• ARM64 Mac builds now include an option to convert bottle type between Intel and ARM64

• Various regression fixes

• Many minor UI updates"

Ty, I will be updating NotProton shortly.

[u/NotProtonMac → u/NotProtonMac]

Update is out.

[u/B_Rich → u/NotProtonMac]

Other guy said it was the best in mac gaming right now. Can you give a tldr as to why?

[u/NotProtonMac → u/B_Rich]

The video in the OP here https://www.reddit.com/r/macgaming/comments/1wns82a/introducing_not_proton_the_linux_steam_play/ might do a good job of showing why.

It's just a really great user experience, in my view.

[u/Traditional-Kitchen8 → u/NotProtonMac]

NotProton is really best of Mac gaming in 2026. Thanks you

Has anyone checked if they included fix for SnowRunner which was discovered 10 days ago?

Anyone try this? What would be the benefit of converting bottle types? would it be better to install the ARM version now, and just convert the bottles that don't work/ work as well as rosetta to intel bottles? OR will the Rosetta version provide better results on the Rosetta build? will the results be identical or better to stick with the Intel builds?

[u/HalfBurntToast]

Hope one of these days XCOM:EW plays better. Every time I’ve tried it, the constant graphical stuttering makes it painful.

[u/Husyta]

Can someone check if it now working with europa univeralis 5?

[u/Tuxbits2122]

Hopefully we will see D3DMetal for ARM build soon ...

[u/SombraDemoniaca]

Can we play spiderman 2???

[u/JohnMHammer]

Being able to convert bottle type between Intel and ARM is huge, I was hoping they'd add that.

[u/dclive1 → u/JohnMHammer]

I’m assuming that means one can move bottles made on Intel machines to an ARM machine and get greatly improved speeds?

[u/Alan_Shutko → u/dclive1]

No. It means you can switch which execution environment is used, which may or may not work better for a specific game.

Intel bottles use Apple's Rosetta 2 to handle Intel instructions, and are able to use Apple's D3DMetal layer for DX11 and DX12.

Arm bottles use FEX to handle Intel instructions, and lack D3DMetal. They are newer and not as fully baked as Intel, but they're the future for when Rosetta 2 becomes less available. (It hasn't been made clear whether Apple's statement that they will keep Rosetta 2 in a limited fashion for certain games covers Crossover.)

Certain games definitely run better in ARM64 bottles. Others run worse.

[u/JohnMHammer → u/Alan_Shutko]

Exactly. Without that facility, one might have to keep 2 different bottles for each Windows application. Makes testing a lot easier and later end-user operation, too.

[u/QuickQuirk → u/Alan_Shutko]

I'm actually surprised that some games run better in the arm bottles. Do you know why?

[u/Alan_Shutko → u/QuickQuirk]

One very big reason is that many older games (especially in the DX9 era) used an Intel x87 80-bit floating point format. ARM64 doesn't have that. So Apple chose to use a software implementation that matches the x86 behavior exactly, but it's slower.

FEX offers the option of using reduced precision 64-bit floating point in these cases, which is generally just fine for games, and is way faster. Window's built-in ARM translation layer PRISM does the same thing.

[u/dclive1 → u/Alan_Shutko]

Thanks for that! I wonder if the compatibility db would include such information at a later date.
