UDK Performance Notes

After having a discussion with Tanguay about how to judge our performance (poly limits, fps etc) he has told us our poly limit would be around 100k polys for our whole environment. However as the performance depends on much more than polycount (shaders, animations, texture passes, post processing etc) and also the fact that we are going to be using a lot of instancing for our meshes (which are only drawn when seen) our limit is less easy to calculate. Tanguay then told us about the 'stat engine' which is similiar to unity's profiler, which runs as you play the game and gives you live information about how the game is running and breaks it down into sections. Keeping and eye on this as we test our level will keep us aware of which aspects need to be optimised and how well the game is running.

Upon further investigation there are many more 'stat' commands that will be helpful for us to monitor our game's performance, here is a link to the wik: http://udn.epicgames.com/Three/StatsDescriptions.html
