Maybe just putting a little sand in the engine, but people should be aware that Omega drivers seem to be "dying". The last version is 7.1, of January 2007, and previously they followed more or less the ATI monthly updates. Meaning, they are now roughly 4 versions "late". Worse, on the Omega site, the last news is from 29/4 stating that "in the next week" he should be posting an update of the Omega's... 3 weeks have passed, and nothing.
Nevertheless, I must say that I use Omega drivers for more than a year and are happy with them (although they do not prevent me from the %*! textures issue in AACW
leure: ); and we are in a difficult period of transition to VISTA compatible drivers. But it seems there is a real risk of Omega drivers becoming "obsolete" in the not-so-distant future.
