Hi everyone, Recently I have been profiling our engine and noticed that the effect section takes a lot time to complete, therefore I ran it through pix and ati's perf studio and found out that the biggest timeeaters are AddRef and Release called from ID3DXEffect::SetTexture, do anyone know why are these two called from settexture?(actually, i can't seem to find a reason to call AddRef and Release right after) Thanks, Szabo Tibor

Well, calling AddRef and Release is the proper way of handling an interface thats passed from one place to another. However it really shouldn't be taking very much time at all to do either.

actually it tooks quite much time, summed up addref and release take up to 0.317ms whereas all the other API calls take up to 3.3ms, so it's cca 10% and I really don't want to sacrifice 10% of the frame time just to do the right thing COM-wise :)
