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: wine-bugs at winehq.org
Reporter: hibbsncc1701 at gmail.com
Distribution: ---
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.
