Just as a side note, I spoke with some guys from ATI at the ARB meeting last week, and they confirmed that chips based around the original Radeon core (R100, Radeon 7500, M6, etc.) have to do a SW fallback in this case. However, the R200 and beyond are capable of handing the post-scale in hardware. -- Smile! http://antwrp.gsfc.nasa.gov/apod/ap990315.html ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel
