      glTexSubImage2D is really slow (20ms) using the latest driver (version:- 14.42.1.5248, date:- 1/4/2010) compared with an older driver (version:- 6.14.10.4953, date:- 21/05/2008), which only takes (0.5ms).

       

      How do I go about getting Intel to have a look at what has happened with their driver.  This performance is unacceptable for our application.  The chip is obvisouly capable because the same code and hardware performs ok with the older driver.  The only issue is that the older driver has some other bugs that we can't live with (these are fixed in the newer version).
