Hi Mahesh, OpenGLES 2.0 defines precision qualifiers (e.g. highp, mediump, lowp) that specify the desired precision for a floating-point result. If the images your driver produces are higher quality images than the reference images, then it's likely that your driver is not handling the precision qualifier correctly. -Tom > > Regards > Mahesh > > **************** CAUTION - Disclaimer ***************** > This e-mail contains PRIVILEGED AND CONFIDENTIAL INFORMATION intended solely > for the use of the addressee(s).
