Hi, Can you add a test showing that FETCH4 is disabled when the bound texture is not a single-channel texture? I sense that there might be applications that enable FETCH4 and then "forget" to disable it when they render from an ARGB texture. A test for DF16 and DF24 would be great as well, but it doesn't belong in this patch and should be a separate one. It's probably best to extend intz_test.
+ if (caps.TextureCaps & D3DPTEXTURECAPS_POW2) + { + skip("No unconditional NP2 texture support, skipping FETCH4 test.\n"); + IDirect3DDevice9_Release(device); + goto done; + } Do you still need this?
+ hr = IDirect3DDevice9_SetSamplerState(device, 0, D3DSAMP_MAGFILTER, D3DTEXF_LINEAR); + ok(SUCCEEDED(hr), "SetSamplerState failed, hr %#x.\n", hr); + hr = IDirect3DDevice9_SetSamplerState(device, 0, D3DSAMP_MINFILTER, D3DTEXF_LINEAR); + ok(SUCCEEDED(hr), "SetSamplerState failed, hr %#x.\n", hr); + hr = IDirect3DDevice9_SetSamplerState(device, 0, D3DSAMP_MIPFILTER, D3DTEXF_LINEAR); + ok(SUCCEEDED(hr), "SetSamplerState failed, hr %#x.\n", hr); This contradicts AMD's description, but I assume you placed them here to show that their docs are wrong and FETCH4 is used regardless of the filter. I think a comment would be useful.
