May be unfixable, but a scene with a lot of walls (test case was 2586 walls) is a serious performance hit. May be ways to lessen this impact:

Turn off Clockwise sweep as EV is not using it?
Check how walls are culled
Switch to rendering smaller triangles for the shadows instead of wasting pixels on lit areas
Make use of attribute instances to avoid uploading the same wall data to the GPU repeatedly
