In the development roadmap Izzy will have these actors as GPU based in the future. For now, in 2.1, a few more gpu actors have been added. In the meantime keep the things you need interactive and do the rest non real time as I mentioned, as the new gpu actors are added (should be by the end of the year), add these functions to your patch. You may also find there are ffgl plugins that will do the same - for these you need v2 there are a bunch of posts in the forum about ffgl plugins and where to get them.
