Thanks for your reply...my main focus is on laptops which generally cannot be
upgraded in terms of motherboards and video...so with that in mind...
Are you running Vista 64-bit on laptops that have shared memory graphics, as
nearly all do? What is the performance like and how much
gaming/multi-tasking are they doing? Everything I heard prior said shared
memory only was an essential no-no for 64-bit Vista for decent performance.
There is very little readily-available information on shared memory chipset
performance as relates to meeting requirements for Vista 64-bit, even though
the MS KB article on it waffles and inlcudes the 64-bit versions. There is
no deliniation or reference to this issue at all, yet it's the supposed key
to 64-bit peformance.
I'd also note that HP is the only company building Vista 64 laptops for sale
at the common retail level that I am aware of, and all of those units have
had at least a GeForce 7600 dedicated video chipset with at least 128MB of
Video Ram. No company, to my knowledge, has issued a Vista 64-bit laptop
that uses exclusively shared memory. The Toshiba laptops that use Vista
Ultimate are all 32-bit installs.
As far as the 3-4GB of RAM issue, MS itself says they are limiting the
available memory on 32-bit systems to 3.12MB, and I have read elsewhere in
these forums that a clean 64-bit install would be required to have a system
see 4GB, rather than an upgrade from Vista 32 to Vista 64. Do you have any
direct experience with that issue? Most of the newer laptops, such as Acer
and others, support 4GB in BIOS.
And as for Micrososft's support of 64-bit...in my humble opinion, the launch
of Vista, especially as relates to 64-bit, has been nothing short of a
fiasco. Not one in ten people shopping at ther local Circuit City, much less
the sales staff, knows that a Toshiba Windows Ultimate machine is loaded
32-bit, whereas an HP is 64. And that's just the beginning of it. We are
now at what...nine months after the Vista launch, and an obscure TechNet
article states that MS is "working on putting together a comprehensive list
of GPU's than can handle Vista 64" and only offers links to vendor sites?
Someone at MS should have given thought to the idea of supporting developers
with financial and other incentives to write 64-bit code and drivers rather
than expecting they could jam it down their throat. If 20% of the Vista
marketing budget had been allotted thereto, everyone would have been in miles
better shape at this point. The vast majority of these companies are not
swimming in the billions in cash Microsoft is, and will see little or no ROI
for years in re-writing software for 64-bit systems or jumping to provide
drivers anbd having to provide support for them with almost zero return.
Again, my thanks for your feedback and I hope to hear more of your direct
