sRGB render target issue
I created an sRGB render target + view and my app clearly appears too bright in the HMD. I used:
Checking the Tiny Room sample, I was surprised to find that it doesn't follow the guideline from:
https://developer.oculus.com/documentation/pcsdk/latest/concepts/dg-render/
and creates a non-sRGB view for the sRGB render target. I am puzzled, can somebody explain what is going on?
OculusRoomTiny: main.cpp:
desc.Format = OVR_FORMAT_R8G8B8A8_UNORM_SRGB; desc.MiscFlags = ovrTextureMisc_None;and verified that ovr_CreateTextureSwapChainDX() returns a DXGI_FORMAT_R8G8B8A8_UNORM_SRGB texture.

ovrResult result = ovr_CreateTextureSwapChainDX(session, DIRECTX.Device, &desc, &TextureChain); if (!OVR_SUCCESS(result)) return false;
int textureCount = 0; ovr_GetTextureSwapChainLength(Session, TextureChain, &textureCount); for (int i = 0; i < textureCount; ++i) { ID3D11Texture2D* tex = nullptr; ovr_GetTextureSwapChainBufferDX(Session, TextureChain, i, IID_PPV_ARGS(&tex)); D3D11_RENDER_TARGET_VIEW_DESC rtvd = {}; rtvd.Format = DXGI_FORMAT_R8G8B8A8_UNORM; rtvd.ViewDimension = D3D11_RTV_DIMENSION_TEXTURE2D; ID3D11RenderTargetView* rtv; DIRECTX.Device->CreateRenderTargetView(tex, &rtvd, &rtv); TexRtv.push_back(rtv); tex->Release(); }
return true; }
