Yeah, ive tried choosing Xrender. I get KDE warning which tells me that KDE couldnt start desktop effects, and i should check my xorg.conf
Here is my xorg.conf:

and here is my xorg log

I don't see anything obviously wrong in your log file. Maybe do some pruning on your conf file -- keep :
Option "AccelMethod" "EXA"
keep the EDID over-rides if you need them :
Option "IgnoreEDID" "on"
Option "NoDDC" "on"
... and comment out the rest :
VideoRam 262144
Option "RenderAccel" "on"
Option "EnablePageFlip" "on"
Option "DRI" "on"
Option "ColorTiling" "on"
Option "EXAVSync" "on"
Option "XAANoOffscreenPixmaps" "true"
EXAVSync is supported by the driver but try commenting that out as well just in case... once you get XRender-based desktop effects working you can try turning it back on again.
