Reduces the number of workers that perform background optimization,
which may reduce the performance impact when encountering a large
number of new pipelines at once.
Reporting a GTX 295 puts us into the highest behind the scenes graphics settings preset bucket and prevents the shadow issue with `FloatingPointRenderTargets` set to false in the lower preset bucket.
NvapiHack needs to be disabled on Linux since the game pings it in the Windows system folder and want's the VendorId to match your GPU. Else the issue will still happen on Nvidia Linux
This allows compiling tessellation or geometry shader pipelines
early while still using the pipeline library path.
Also removes compute shaders. Since API-provided compute shaders
are always compiled early, supporting them is no longer needed.
Apparently this regressed something, but the reporter who asked
for this fix in the first place did not specify what, so let's
just revert this and break the whole thing again until we get
something to actually work with.
This reverts commit 5115d80d51.
Unreal Engine 4 titles use AGS/NVAPI to try and enable
HDR globally.
They can key this off IDXGIOutput::GetDesc1's ColorSpace
being HDR10.
Many of these UE4 games statically link against AGS.
This is a problem as when UE4 tries to enable HDR via AGS,
it does not check if AGSContext, and the display info etc
are nullptr unlike the rest of the code using AGS.
So we need to special-case UE4 titles to disable reporting a HDR
when they are in DX11 mode.
The simplest way to do this is to key off the fact that all
UE4 titles have an executable ending with "-Win64-Shipping".
We check if d3d12.dll is present, to determine what path in
UE4 we are on, as there are some games that ship both and support HDR.
(eg. The Dark Pictures: House of Ashes, 1281590)
Luckily for us, they only load d3d12.dll on the D3D12 render path
so we can key off that to force disable HDR only in D3D11.
SDL >= 2.0.9 permits passing a nullptr window to
SDL_Vulkan_GetInstanceExtensions, so there's no
point in going though the work of creating a
window just to call this function.
Sometimes we can't get an EDID if things aren't plumbed fully, or some displays just have broken EDIDs.
This accounts for both of those cases by using some dummy data if we are missing information.
Fixes value reporting to match Windows on common displays such as LG OLEDs.
Adds the ability to punt the global colorspace into HDR from SetColorSpace1.
We have no way of checking the actual Windows colorspace as the
only public method for this *is* DXGI which we are re-implementing.
So we just pick our color space based on the DXVK_HDR env var
and the punting from SetColorSpace1.
We might expand on this in future, but this is good enough for an
initial implementation.
