Im not sure I’ve ever seen InterlockedAdd (hlsl) work correctly on Nvidia. Works on AMD tho. Can’t help but wonder if I’m doing something wrong, and AMD is more permissive. Seen a few reports of other people noticing the same thing.

Is the underlying data in your buffer R32_UINT formatted? I always steer clear of atomics on RWBuffer because someone could change the buffer to be R16_UINT or R8_UINT behind the scenes and then atomics won't work any more.
It's definitely R32_Uint, although I'll take the advice about avoiding interlockedadd on them. I'm not sure I could find a way not to in this case. Unfortunately I can't go into too much detail without risking breaking NDA.

If it comes to it and the NDA issue becomes an impediment, I can take a look in a professional capacity away from the prying eyes of Twitter. I expect a mutual NDA exists between our two companies on paper somewhere.
