The old css fps configs still work fine, there are only a few cvars that dont work anymore but they did nothing before either (like r_phong).
But multicore support there are new cvars and also a few more below:

Only just tested the above and it didnt seem to do anything negative. FPS was the same though. So I think it comes down to using mat_queue_mode "2" or "-1" (both are the same thing)
