Summary0000035: Renderer performance is slow
DescriptionFor large maps (i.e. level-sized rather than testmaps), the Lighting render mode has very low FPS, takes too long to activate and uses up too much memory (causes swappage on a 1GB machine).
TagsNo tags attached.

Display Lists implemented for model objects, possibly provides some performance improvement.

Assigning to myself; I will take overall responsibility for this but it is obviously a large issue that everybody can contribute to.

Next up: Implement DLs for AI models (these are separate from static models), and look at VBOs for patches.

DLs for MD5 models now implemented.

Just for the record: I implemented the use of VBOs for patches a while back but there was no noticeable performance increase to observe. I assume that for better performance the overall strategy needs to be changed towards removing draw calls. Right now each patch/brush is submitting its own (often very few) vertices - combining those might be a worthwile improvement. I figured the Octree cells could function as some sort of container for that, such that all brush geometry using the same shader in the same Octree cell of a certain size is combined.

Will close this as it's very generic. Specific problems or suggestions can go to separate tracker entries.
