I believe I’m getting slowdowns due to a big hit with tessellation. Now I’ve been told a way to get around it is to triangulate my object (a simple door), but it doesn’t seem to change anything.
In addition, I only get tessellation hits sometimes, not all the times. even though I’m always looking at this door, the problems seem to happen when my character is going from off screen in front of it. It’s hard to tell as these are intermittent drops in frame rate, and I believe they’re due to that (I have to click on the performance monitor just at the right time… would be nice to have a history there). So this intermittent tessellation hit doesn’t seem directly related to whether or not the object is triangulated, but to something else - probably related to coverage etc.
Actually I don’t even know if that’s a real factor, because when it happens, it takes up a long long green line in the perf mon but then the Draw Touch UI - further down in the list , seem to start its green line from that point - whereas when the tessellate entry is not there it starts it from the beginning: in the first case tessellate + Draw Touch UI is the same as the Draw Touch UI in the second case (more or less).
what would make that happen? Meaning, is Draw Touch UI involving possibly any tessellation? If it is, why would it take so much longer when tessellation doesn’t happen/is not listed in the perf monitor? They seem closely related.
