[SOLVED] Tear Free feature on Catalyst >13.1 causes 30 fps

I've observed a strange thing with latest Catalyst drivers.

Version from old official packages catalyst-dkms-13.1-2 and catalyst-utils-13.1-5 works almost normally (on XServer 1.13.3).
But in later Catalyst versions, including catalyst-test-13.6-3 from AUR, Tear Free Desktop option causes 30 fps.

Without this option fps is normal (60 with VSync enabled), but causes unwanted effect in video and games.

Hardware: AMD Radeon HD 6450.

UPDATE: FPS with Tear Free is normal (60) in fullscreen windows.

I have the exact same problem with my system.  I started experiencing this after installing arch after adding a second 7950 and a new install on an SSD.  Are you running a dual GPU setup by any chance?

not to critisize your card but on the lower end ones like the one I/we have youll have much better
luck with the open source driver ie; xf86-video-ati I advise switching to it if you can.
