Slayer's Testaments doesn't run with 1.10

1

Complains about QuakeC stuff related to particles. 1.05 runs but also sometimes crashes in QuakeC. I wouldn't be surprised if it's not correctly querying for available QuakeC extensions though, the...

Please reconsider the new memory usage flags

1

The new API is extremely confusing. It should not pretend to know better what memory type I need. E.g. people will start using `VMA_ALLOCATION_CREATE_HOST_ACCESS_SEQUENTIAL_WRITE_BIT` for staging buffers because hey, they...

TextureD3D11::resolve tries to call ResolveSubresource on depth buffers

24

If the frame buffer contains a depth buffer with MSAA the D3D11 backend will error with e.g. `D3D11 ERROR: ID3D11DeviceContext::ResolveSubresource: The Format (0x27, R32_TYPELESS) is never able to resolve multisampled...

macOS packaging

* Performance is much improved on my Ryzen machine. I doubt this will be different on Intel, but maybe do some tests if possible. I used ad_sepulcher because it's one...

Broken sampleRateShading and differentiating SSAA from MSAA

5

Setting `VkPipelineMultisampleStateCreateInfo::sampleShadingEnable = VK_TRUE;` and `VkPipelineMultisampleStateCreateInfo::minSampleShading = 1.0f;` should enable supersampling, but it does not. It just behaves like regular multisampling. Either this is a bug and it should be...

Please consider reverting AppImages to be built on 18.04

7

Or update the glibc version notice in the release docs. Building AppImages on 20.04 or 22.04 will produce binaries that require significantly newer Linux versions and I honestly do not...
