It can go higher actually, just that when I setup my test devices I had a "ought to be enough for everyone" moment when typing `options amdgpu gttsize=110000`. I guess this number spread too far, heh.
Apologies, I stand corrected. Do you have a reference for this? I'm genuinely curious why the 96GB "limit" is so frequently cited - I assumed it must be a hardware limitation.
