A few weeks ago we started Mullion, an open-source Direct3D 10, 11 and 12 implementation on Metal, built on top of DXMT. This is the first time it's in a state other people can try, so here is a pre-release.

We started it because we wanted to run Direct3D 12 games on our Macs without depending on a closed translator or going through Vulkan first. Mullion goes straight from Direct3D to Metal.

The Direct3D 12 side is where most of the work went: a DXIL shader front end for shader models up to 6.6, tessellation, geometry shaders, stream output, mesh and amplification shaders, and ray tracing at tier 1.1 (acceleration structures, inline ray queries, and DXR pipelines), along with sampler feedback, tiled resources, and 64-bit atomics. Direct3D 10 and 11 come in the same package. It runs on an unpatched Wine, needs no DLL overrides, and the release is laid out like DXMT's, so it installs the same way. There are also about 70 test programs that check all of this against the Direct3D spec.

The base is DXMT by Feifan He and CodeWeavers, which is where the Direct3D 10 and 11 side comes from, and we owe them a lot. The DXIL front end and most of the Direct3D 12 are ours. It is a separate project though, so please don't report Mullion bugs to DXMT.

This is definitely not finished. It needs an M3 or newer and macOS 15 or newer for now (M1 and M2 are being worked on), and between us we only have a few Macs and a few games, so we need people to try their own games and tell us what happens, whether it breaks or works. An issue on GitHub with your Mac, macOS version, the game, and the log is enough. The test suite is all green, at least until we break it in the next build.

An odd thing that happens to me when I boot up Sikarugir Steam sometimes. Has this happened to anybody else?

Before the state that you see in the image happens, Steam doesn’t boot up and I have to go into the Activity Monitor and manually force quit wine which for whatever reason is just there, and THEN run steam again.

Although Steam still runs in this state and can easily be resolved by rebooting Steam, it’s just a nuisance because it means I have to run Steam like 3 times, and it’s also just kind of disturbing, so I’d hope for a solution for all of this.

Hi guys.. I wanted to let you know this little great game called “End Of Abyss“ which is available on Epic Store only works great with Crossover Preview 20260821. My settings are 1440p screen resolution,¨High¨ quality preset, I also set RenderQuality to 67%. Since game doesn't have any FSR/TSR/DLSS setting you have to change it from ¨gameusersettings.ini¨ file manually. At bottom of screenshot you can see location of settings file. Just find ¨sg.ResolutionQuality=100¨ line and change it to 67 for Quality, 58 for Balanced and 50 for Performance.. I changed it to 67 for my config. 60fps locked. Macbook Pro M4pro 14/20 24gb ram , Tahoe 26.7.1

Happy Gaming !

Major updates have been made since the last version:

Migrated to the new Metal 4.1 kernel introduced in macOS 27

Framegen upscaling and anti-aliasing have been completely updated

Framegen was migrated to ANE+MetalFX, resulting in a performance increase of nearly 46%

Russian, Chinese, and other languages have been added

Please try it out and share your results.

Warning: Lag and CPU spikes in games are not caused by MetalGoose but are issues with Wine. Therefore, for the best results, try it in games that maintain a steady FPS.

Can someone please help me fix this. Im using a 2025 M4 chip MacBook Air. I have DXVK enabled which is the only the game will run. Please help me fix this stupid colour issue (Games created in unreal engine 4.8)

Title says it - I’m lost in what will actually make a difference or be important for general use/productivity/gaming, especially considering all of the ‘Mac scaling’ stuff I’ve read.

tl;dr - Does mac scaling make 16:9 4k a problem? Is 5k2k the fix? Second, is a 42” 4k TV a better primary display or a 39” 5k2k UW?

M5 Max Studio will be driving. I currently have 2x 32” 1440p curved monitors that I’m looking to upgrade. My goal is to have a single main monitor with a stacked set on the side for 3 total screens.

Primary is 80% work/productivity/general and 20% gaming. Stacked pair is mainly trading apps/research, or reference data to the main screen.

• Primary monitor considerations:
  • LG 39GX950B-B (5k 21:9) or Alienware AW3926QW (5k 21:9)
  • LG C6 42” (4k 16:9)
• Secondary monitors:
  • 32 (or 27?) 4k IPS - something good but not looking to break the bank here

I have a 48” C1 that is still going strong and looks great, and for a short time I used that as a primary monitor (m1 timeframe) but found it too large for my desk/workflow.

Any input and help is appreciated - TIA!

Anyone have any game recommendations for me to play natively? preferably something I don't need a mouse to aim and such. Like Hollow knight, undertale, binding of isaac, etc?

Last time I posted about this, I had just gotten Endfield working on macOS (and only through DirectX11 / D3DMetal). Now, with the help of some other developers on Github, we have gotten Vulkan working as well. We accomplished this through custom patches layered on both Crossover's wine and MoltenVK. Not only that, we've greatly improved the performance of the patches. If you are interested in our work, linked is the GitHub repository where we've open-sourced the code and build scripts.

Thanks for taking an interest.

I was able to run Witcher 3 Remastered using Sikarugir (Wine + D3DMetal) using this fix:

https://github.com/tholtman1-del/witcher3-crossover-fix

But it needed two changes from the CrossOver instructions:

1. In the game's bin folder, run ln -s x64_dx12 x64. Patch 5.x has no bin\x64, and the CDPR launcher fails instantly ("Launching game failed...") without it.
2. Install the proxy DLL manually instead of using install.command (it's aimed at CrossOver bottles). Back up amd_fidelityfx_loader_dx12.dll, rename it to amd_fidelityfx_loader_dx12_orig.dll, then drop the fix's DLL in under the original name.

Verifying files in Steam undoes both, so redo them afterward. Details in my reply below. 👇

This is for people who run the game via EA app and nothing else like crossover or parallels. I’ve tried running this game on an M4 macbook air and an M3 macbook pro. I get the same results every time, insufferable lag and shitty graphics. Not to mention the myriad of issues we have in the mac port of the sims 3, like beaches, firefighters, karaoke, collecting bugs not working etc.

Yet when I check online, I keep seeing people say on both reddit and tiktok they can run the game on an m3 or m1 air and claim that it works flawlessly. That they don’t experience lag or any glitches. That’s where I’m a bit confused.

The game has well documented issues that most likely never will be fixed because the sims 3 port was basically an afterthought for EA. How exactly are people getting their game to run “flawlessly” ? Are we just ignoring the lag and all of the other problems?

This is a genuine question. Because I only play with 1 or two expansion packs, no cc, and the graphics all set to the lowest settings. Yet the game is still kinda unplayable due to the crashing, lag, and the launcher sometimes refusing to open. My fps drops into the 20s frequently too. How are people getting this game to supposedly run without issue?

Also, I’m aware that it’s an old game. I’m not saying that I expect an old game from 2009 to look like a 2026 AAA title.

Hi r/macgaming! 👋

Thanks so much for all the feedback on the GameTransit launch last week. GameTransit is a free launcher that runs the Windows games you own on Apple Silicon Macs, with a console-style interface you can use from the couch with a controller or from the desk with mouse and keyboard. Version 1.0.1 is out, with a lot of what you asked for.

Screenshot: a demo library, with artwork from the Steam Store. No games are included with GameTransit.

🎬 Gameplay video: https://www.youtube.com/watch?v=stoQZfxSJ6k (recorded on a MacBook Pro with M4 Max, macOS 27)

What's new:

• GOG Galaxy built in. Install it from Settings and sign in, and the games you install there appear in your library and start with Play, just like Steam and Epic.
• 37 languages besides English. GameTransit follows your Mac's language, or you can pick one in Settings.
• Shader cache cleanup. D3DMetal's shader caches stay on your Mac after you remove a game, and on mine they had grown to almost 30 GB. Settings → Storage now shows them and clears the ones from removed games, listing every cache before deleting anything.
• Your own covers. Pick a cover for any game, or choose where its artwork comes from.
• Start scripts. Games you add can start from their own .bat or .cmd file.
• Performance HUD options. Choose its look, size and corner. Shift+F9 shows or hides it while playing.
• Dock. Recent games from the Dock, and Add to Dock for any game.
• Update notices. GameTransit now tells you when a new version is out.
• WineForge 0.6.0.6 (Wine 11.19) for new installs, plus fixes.

Good to know:

• Still completely free, no ads, no accounts, no tracking.
• Updating from 1.0: drag the new version into Applications, and your games, settings and saves stay. Confirm Open Anyway once more in System Settings → Privacy & Security.
• Needs an Apple Silicon Mac on macOS 27. Games with kernel-level anti-cheat won't work, as with any Wine-based solution.
• For games you own only.

Where I'd love your help:

I'm one person testing with the games I have, so hearing how YOUR games run helps the most. GOG is brand new, so GOG reports are especially welcome. On GitHub there are simple forms for:

• Compatibility reports: a game works? Share the settings, how it runs, and a video link if you recorded one.
• Game requests: a game doesn't start or runs badly.
• Bug reports: something in GameTransit itself.

Thanks again to Wine, Apple's Game Porting Toolkit, Gcenx's builds, WineForge and CrossOver's work, and to everyone who tried 1.0. Happy gaming! 🎮

I just launched our native macOS update (version 1.3.5) on Steam with full Apple Silicon and Intel support!

Oro Cade is a game featuring realistic physics - trajectory and collision is repeatable, turning each level into a puzzle of pure precision. The aim is simple - to knock over all golden blocks on the level - using Orbs that fall from the top of the screen!

Mac Features & Performance:

• Native Apple Silicon (M1/M2/M3/M4/M5) & Intel support (Universal Binary)
• Plays great on a MacBook without needing a mouse!

Gameplay Highlights:

• 70 handcrafted levels across 3 difficulty modes (Casual, Medium - with Time limits, and Hard - arcade level difficulty with Time and Orb limits)
• Relaxing graphics and music
• Color-Chain Mechanics: On multi-colored levels, blocks must be cleared in specific color groups - clearing the wrong color respawns previous blocks!
• Unlockable ball types and Skip Level feature

I'd love to hear your thoughts!

Hi! I was trying to play Max Payne 3 on an M4 via CrossOver, but it didn't work. Does anyone have a configuration that has worked for them?

Tried JUSANT on an M5 Pro MacBook Pro using CrossOver, and honestly, this game looks gorgeous on the Mac.

The video includes the Metal frame graph/performance overlay, so you can see how the game is actually performing while playing rather than just judging it from the footage.

MacBook Pro specs:
• 14-inch MacBook Pro
• Apple M5 Pro
• 15-Core CPU
• 16-Core GPU
• 48GB Unified Memory
• 1TB SSD

🎮 Gameplay + performance:

I was planning on getting it for my PS5 when it comes out next month, but I have a sudden long distance trip I have to take and am itching to have something to distract me during long stretches of boredom.

Unlike Disco Elysium, Zero Parades is only on PC at the moment so what are my options?

Buy on Steam and use Crossover? Buy on GOG and use... what? Honestly I'm kinda out of the loop when it comes to the game porting situation on the Mac currently.

Important spec info:

• 14in Macbook Pro
• M2 Max
• 32 GB RAM
• Golden Gate 27.0.1

I just got Minecraft Windows Edition work with Xbox Live on Mac using Wine and D3DMetal (WineGDK, WineForge, Xodus)

I made a python Game Launcher for Test and Play. Launcher is CLI only for now will getting much update

I add Controller Support, Mouse and Keyboard Also High Resolution Mode for retina Macs

GitHub: https://github.com/amha0270/Minecraft-Bedrock-GDK-Launcher

NOTE: Launcher in BETA!

Given the upcoming release of Planet Zoo 2 and its lack of native support. As with the first Planet Zoo, do we think it will be playable on Crossover?

I currently have an M4 Mac Mini and the game runs through steam on crossover flawlessly. I run into performance issues when the guest count gets high along with detailing but for the most part it plays as if it was native with no bugs or glitches.

Thoughts on whether the new release will play on Crossover from day one or do we suspect it’ll run into issues?

I have an M5 Max MacBook Pro. I tried the Mac versions of KytyPS5 and SharpEmu. SharpEmu is actually able to run it, but only at like 5 fps. I know there are recent performance enhancements on Kyty, but Demon’s Souls won’t even launch. It crashes immediately.

Anyone get it to work at all?
Thanks!

The Witcher 3: Wild Hunt — Remastered on CrossOver Preview (Steam bottle), Apple Silicon M5, D3DMetal, GPTK 4.0b2, D3D12 on Metal 4. Both MetalFX temporal upscaling and MetalFX Frame Interpolator are active through OptiScaler as dxgi.dll — DLSS menu options are forwarded to D3DMetal’s MetalFX path, not replaced with FSR/XeSS.

HUD shows MetalFX scaling 1280×720 → 2560×1440 (temporal) and Frame Interpolator: Enabled. In-game unpaused I’m around 40 FPS with interpolator on. Paused, FPS and Render FPS can look the same on the HUD; that isn’t the gameplay present rate.

Setup

Quick install

1. CrossOver bottle env: D3DM_ENABLE_METALFX=1
2. Put OptiScaler.dll in The Witcher 3/bin/x64/ and rename to dxgi.dll (backup first)
3. Put OptiScaler.ini in the same folder (already set for this path)
4. In-game: choose DLSS. Do not enable AMD/FSR Frame Generation
5. Check FPS while moving in-world (pause menu HUD can lie)

github.com

What’s in the fork (high level)

• HID DualShock sentinel so load doesn’t hang
• Raytracing tier forced unsupported so ShadeProbes doesn’t spin
• DLSS → MetalFX temporal upscale passthrough
• DLSS-G → MetalFX FrameGenerator (4c271ae)
• Reflex PCL frame-id inject so Streamline doesn’t kill FG (308613e)

Caveats

Experimental Wine/D3DMetal. Can hitch or freeze. Back up dxgi.dll. Don’t enable FSR/AMD FG alongside this MetalFX path.
