Bug ID: 53442
           Summary: Total War Shogun 2 needs D3DX_FILTER_BOX for memory
                    management.
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: d3d
          Assignee: [e-mail]
          Reporter: [e-mail]

Total War Shogun 2 uses the D3DX_FILTER_BOX filter to downscale it's textures.
Both during normal usage, but more critically, when it's VRAM budget is low or
over-committed.

This can be seen on Intel GPUs in the game's stderr output with a line similar
to:
---snip---
** Downsizing Textures, Over Budget by : 115 Mb
---snip---

Followed by (in wine-7.12 or older) or prior (in wine-7.13 or later) multiple
fixmes:
---snip---
0024:fixme:d3dx:D3DXLoadSurfaceFromMemory Unhandled filter 0x5.
---snip---

See also the attached log from wine-7.13.

As this filter is used for memory management in a 32bit game, it's
implementation would help alleviate some OOM errors.

It won’t. The implementation would maybe help downscaled images look nicer, but
resampling is performed anyway by the function, just proper filter is not
applied.
