The zigzagged edges (those little deterministic squares of corruption) are a HiZ issue. Currently I am only fixing Zmask (zbuffer compression).
I've made a new patch, which contains new bug fixes and performance should no longer regress. Could you give it a try?
This patch improved a lot. Openarena is still fast as before. Corruption on sauerbraten is almost fixed (other than object edges), there are however still some little white clouds in some zones.
