That would come under the part about "manipulating large chunks of data that can be processed 64 bits at a time instead of 32." But all that is beside the point. The original query was about drivers that were clearly broken in the 64bit version but potentially OK in the 32bit version and not whether 64bit was better than 32bit. That's why I suggested using the 32bit version as a workaround, ideally using a Live CD before re-installating in case it was broken as well, and wait for the bugs to be squished. The bit about 32bit vs 64bit was just to make the point that for many "everyday" tasks the advantages of 64bit are not all that great. The flipside of that is, of course, that if you do a lot of the things that 64bit is better for (converting audio data between formats, for instance) then the disadvantages of 64bit, such as those pointed out by Jerry, are not that great either. For the record, I run 64bit versions of both Linux and Windows (I need Creative Suite for myself & Office for work) and wouldn't want to have it any other way. -- Andy The only person to have all his work done by Friday was Robinson Crusoe -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
