Now I am using mesa 9.2, and works good, but not enought for steam linux games
    Are you using the SB optimizations ? My recollection is that they make a big difference on low end hardware. The hd4250 has a 40 ALU shader core, so along with hd2400, hd3450 etc... are the smallest r600-family shader cores we made.

    No, Im not, but now I want to use it
    So, according to this article from phoronix
    http://www.phoronix.com/scan.php?pag...tem&px=MTM2MjA
    it says
    "[...] can be enabled via the R600_DEBUG=sb environment variable"
    So, how can I activate it? Where do I have to put that sentence, inside which file?
    Thanks for the help
