Marvel's Spider-Man 2

Characters stay in a T-pose and the symbiote breaks on M1-M4 Macs: D3DMetal reads and writes typed buffers only to element 2^28.

GPL-3.0-or-laterOriginal idea: macprotips Reimplemented in MacGameFix

What you see

Characters stay in a T-pose; the symbiote shows up as spikes, a flat black sheet, or not at all; brief black blocks flash in the opening sandstorm stage

Why it happens

On M1-M4 Macs, D3DMetal returns 0 for typed buffer reads past element 2^28 and drops typed writes past it. The black blocks come from a missing barrier after the volumetric fog copy

What the fix changes

macprotips': the wide R32 views made raw, and four shaders rebuilt raw from your own exe. Ours: no DLL override, and a UAV barrier after CS_VolumetricFogCopy

The code

macprotips': the wide R32 views past element 2^28 are created raw, which D3DMetal reads in full.

            log_msg("Wide typed view (%u elements) created as a raw view", desc->Buffer.NumElements);
        orig(device, resource, &raw, handle);
        return;
    }
    orig(device, resource, desc, handle);
}

Ours: a UAV barrier after the volumetric fog copy, which removed the black blocks in the sandstorm stage.

Thanks to

macprotipsThe diagnosis, the raw views and the four rewritten shaders (public domain). MacGameFix adds a carrier that needs no DLL override and a barrier after the volumetric fog copy.
