I just change the format of the swap change and that happens
sRGB was enabled? how?
Your pixel shader is emitting values outside the range [0;1] thus was getting clamped?
but the pixel shader value always gets clamped in the end in those two formats,no?
You're uploading data from CPU and now you forgot to account the change in bpp size ?
no, all the colors you see in the image are created in the shaders
