The lightmaps aren't updated at all yet, so everything is static. Figuring out how lightmap data gets to the gpu was a chore thanks to the spaghetti in the bsp data, and then I'd forgotten that I was pre-expanding the light data to rgb so wound up with weird lightmaps, but without water or particles, demo1 is getting 5000fps at 800x450, and it seems to be CPU limited.
