I'm having some problems getting var to work with my system. Basically I am switching my memory to be allocated by the wglAllocateMemoryNV function, then I am calling glVertexArrayRangeNV then glEnableClientState(GL_VERTEX_ARRAY_RANGE_NV);, afterword everything is left as normal. But alas all the vertices are jumbled. What kind of VAR mistake could cause this?
What chipsets can write combine to multiple arrays?(I read previously P3's but do athalons as well?)
As well can you obtain writecombing with a loop such that
for all verticies
perform an action
write result to VAR array
Is there a good document on the web about the best techniques to do write combining?
