Why is the wireframe rendering so slow compared to solid? I wanted to try to overlap wireframe view with the solid view for debugging purposes as I work on the terrain, but just switching to wireframe mode the framerates drop from 900+ when on solid mode to about 70. It's not a heavy scene either, I don't have the poly count but it's probably a couple of thousand. Is this normal? (By the way this is running on debug libraries). Here are some fraps screenshots. Edit: probably some info is needed here: DX10, win10x64, gtx 970 https://ift.tt/eA8V8J
