i have a question that bothers me. i read not long ago in a thread that when querying a few occlusions, the app should let the gpu work, and while that keep the cpu busy. only than to get the query results from the card. so my question is, will it be faster to let the cpu work? i dont see why, becuase it will not speed up the gpu, and that means that the occlusion test is slow, as we could see from that thread subject. so what is going on? can someone explain this cpu/gpu paralelizm thing?
