Fixes a GPU hang when closing Dark Souls 3 as well as similar
undesired behaviour in other games that continue to use the
DXGI swap chain after the window has been destroyed.
We do not have to do this anymore since we'll bind a large
enough dummy buffer. Considerably reduces code size in shaders
which access a large number of shader constants.
We will use this extension in order to implement vertex
binding divisors other than 1 for per-instance attributes.
Will be *required* as soon as support by wine and Vulkan
drivers is widely available.
We no longer use the 'oldSwapchain' member in the swap chain description
to replace an existing swap chain, but rather destroy it altogether and
create a new swap chain. While this is less than optimal, it might help
solve some swap chain-related issues such as #277.
An alternative to manually creating a framebuffer object and binding
it via bindFramebuffer. Future optmizations can use this to bring
down the number of redundant render pass changes.
- Do not report MIP_AUTOGEN if the image format cannot
be used as a color attachment
- Do not report SAMPLE_COMPARISON and GATHER_COMPARISON
if the DXGI format has no corresponding depth format
- Only report image-related features if the image format
can actually be used as a sampled image
Some games do not compute the number of mip levels of
a texture or texture view correctly, so we should work
around this by capping it to the highest possible value.
If this method is used to clear a view with a floating point format,
we need to create a compatible view with an integer format in order
to clear the resource with the correct value. Fixes some calls to
this function in Rise of the Tomb Raider and other games.
No `std::mbstowcs` string conversion needed than.
W/o this change I have different output when running `dxgi-factory.exe` compiled with MinGW:
* `Output 0:`
```
\\.\DISPLAY1 (default)
\\.\DISPLAY1 (DXVK MinGW)
\ (DXVK winebuild)
```
With this patch all three variants are identical (`\\.\DISPLAY1`)
p.s. same problem in dxgi_adapter.cpp, but `deviceProp.deviceName` is vulkan structure parameter (char deviceName[VK_MAX_PHYSICAL_DEVICE_NAME_SIZE]).
This is part of a major refactoring process regarding DXGI->Vulkan
format conversions. Since we don't patch format lookup tables any
longer, we can create a global lookup table.
