Format unsupported for random writes - RG11B10 #8

Open lingllting opened 1 year ago

URP version: 10.4.0 Unity version: 2020.3.3 Unity uses B10G11R11_UFloatPack32 as hdr format(no alpha needed), but it seems that this format is not supported for random write. When force the format to R16G16B16A16_SFloat, it works as expected. But gpu overhead is huge after enabling FSR even for the performance level, the compute shader costs a large portion of the total execution time per frame. Is there any idea why this happened?
