you cannot upgrade Vertex Shaders and Pixel Shaders - they are build into your video card
as the new windows aero requires at least a shader version 2.0, unfortunately, you will not be able to run it
the drivers ATI supplies for Vista only apply to Radeon 9500 and above
I realized my last thread was too long for most people to read easily, so I'm slimming it down a little bit.
I have two systems which I'm curious to whether I can upgrade to Vista Home Premium. On the CNet Readiness Adviser Test, (that's weird, Mozzila flagged "Advisor" on spell check) they give their recommendations, but what if I want to know the basics? I'd rather upgrade my functional systems instead of upgrading to a new system with Vista, but at what level will my system remain functional?
*I have two three-year-old systems running XP Home.
My first system runs an Intel-based HP Pentium 4 Hyper-Threading technology running at 2.8GHZ. (I think model number a350y)
I recently upgraded my integrated graphics card to a 256mb Radeon 9200 Series. I failed 2 of the 5 categories on CNet's Readiness Advisor (take that, Firefox!) because my graphics card has Vertex Shader Version 1.1 and Pixel Shader Version 1.4, when both of them need Version 3.0. Another main question, where do I go to upgrade these drivers?! If I want Vista, it seems necessary to update to version 3.0, but in order to do that, I need to know where!
My other system (a450e) is an AMD-based HP running an AMD 64 3200 running at 2.0GHZ.
On this system I have 1GB RAM, and a 128MB Radeon 9200 Series video card. If I can upgrade the drivers, (once again, need the same drivers to be updated; where?) My CPU was only rated at 3.20GHZ, which didn't meet the 3.80GHZ recommended, but once again it's just a recommendation. Would my system be acceptable for Vista Home Premium? Keep in mind I haven't upgraded this system to SP2 yet (I haven't backed-up files yet; will I need to upgrade to SP2 before possibly upgrading to Vista?)
Also for Vista, I heard about ReadyBoost (where you can add a USB drive to act as additional RAM)- it would be no problem to add an extra 1GB of ram to each system.
Thank you for your time and I'm curious to see if my systems can run Vista Home Premium! I tried shortening this post more than the last one, but I'm not exactly sure how much that worked! =]
