I don't think so, but maybe for uniform data.

neobrain: Which kind of buffer do you want to get (generally, not OpenGL):

• write combining

• flush cache after use

• main memory buffer

• staging buffer which updates a vram one

I haven't heared anything about cache invalidation, so I guess it's slower than write combining.

And for vertex+index data, which we only use once, I doubt that any vram buffer will be faster than a main memory one. So coherent will be exactly write combining + main memory based.

For uniform data, which is used by far more often than once, it may be faster to use vram. But we only use some KB of uniform data and we use them in order, so it should stay in gpu cache. -- Does coherent disable the gpu cache? --

I'm sorry if anything here is wrong as I've only guessed how gpu buffer handling works, so does it really work?

Can this issue be closed after the recent Coherent Bit stuff?
