Just a heads-up: If I disable Sync to VBlank in CCSM, and keep Tear Free Desktop enabled in AMDCCCLE, I get normal performance, as well as no tearing (because AMD is handling it at the driver level). I guess the whole issue was because vblanking was being done twice (once at the Compiz level and another at the FGLRX level), and this was putting a huge load on the GPU with performance regression.
