Unfortunately, Thief cannot have both "tex_filter_mode 0" for chunky pixels and anisotropic filtering. However, there's a way.
The "cam_ext.cfg" file has a setting for texture filtering. But the modes don't allow for "no filtering" (chunky pixels) with anisotropic filtering, only "linear filtering" (blurry/smooth pixels) with anisotropic filtering.
Given "tex_filter_mode 0" in cam_ext.cfg:
Code:
; set texture filtering mode: 0 no filtering, 1 linear, 2,4,8,16 anisotropic (number is sample size)
tex_filter_mode 0
Anisotropic filtering can be enabled outside of Thief.
In Linux/Wine, one way is to use the environment variable "AMD_TEX_ANISO", which can be set to 0, 2, 4, 8, or 16.
For example:
Code:
AMD_TEX_ANISO=16 wine THIEF.EXE
I assume this can be done in Windows as well, but I don't have a machine to test that.
Other ways include:
* Nvidia Control Panel
* AMD Radeon Software
* AMD Catalyst Control Panel
* Linux AMD OpenGL "AMD_TEX_ANISO" environment variable
* Linux Vulkan "RADV_TEX_ANISO" environment variable

The likely reason is that in D3D9, D3DTEXF_ANISOTROPIC is a D3DTEXTUREFILTERTYPE, while for example in Vulkan, it's a separate VkSamplerCreateInfo::anisotropyEnable parameter. So you have to find some way to externally force anisotropic filtering with D3DTEXF_POINT. AMD_TEX_ANISO seems to do exactly that. Looks like it comes in as max_ansio (sic) here: (
