The "Vista-Capable" Debacle Spreads To Acer
N!NJA writes in with a Register story on a lawsuit filed against Acer for selling Windows Vista on an underpowered notebook. Of course anybody can sue for anything; it will be interesting to see if this action goes forward in the courts. "With a lawsuit filed Wednesday in San Francisco, California, two residents of Fostoria, Ohio seek damages and relief from the world's third-largest computer maker after purchasing a sub-$600 Aspire notebook that included Windows Vista Premium and a gigabyte of shared system and graphics memory. In its official "recommended system requirements," Microsoft recommends that an additional 128MB is required to run the Premium incarnation of its latest desktop operating system. ... Microsoft says that the Premium, Business, and Ultimate editions of Vista will run on 512MB systems — with certain OS features disabled. In the beginning, Redmond called these 'Vista Capable' machines, and it's facing a separate lawsuit over this potentially misleading moniker."
Probably even with shared graphics memory, resulting in something like 448Meg usable? Windows XP SP0 and SP1 ran on 256Meg RAM, SP2 seems to need 512Meg RAM, SP3 seems to need a bit more (but I never tried taht one on low-memory machines). Vista on such a machine? Eeeuh.... I don't think so.
That said, they seem to have paid quite a lot of money to get a RAM upgrade.
Linux runs fine tough on such "low-memory" (I had harddisks smaller than that, like 20Meg!) machines.
Ahhh...the great dumpster continuum. Many a free computer will be found there. -- sowth (748135)
It works fine with 512... Its just incredibly slow!
Aero offloads the GUI onto your graphics card if it is capable of DirectX 9. It provides a faster, tear free interface, and if you notice DWM.exe (Desktop Window Manager) uses only 0-1% of CPU during use.
If you disable Aero and fall back to GDI, DWM.exe will disappear, and explorer.exe instead takes the load, usually using 1-5% of my CPU (at least on this machine).
In general, you should get better performance if you have a decent video card. If you are using the desktop anyways, why not utilize the GPU?
A couple of considerations:
1. Vista uses more GPU ram with each window. If you have a shared memory GPU, it's conceivable that it would be too slow when you start opening many windows. Or if your GPU just doesn't have a lot of RAM.
2. Maybe your GPU isn't as power efficient as using the CPU for rendering the windows. Battery life could be affected.
3. Windows 7 with driver model 1.1 uses a constant amount of GPU ram for any amount of windows (steaming in textures instead of keeping them loaded). It also re-enables GDI 2D HW acceleration which was disabled in Vista, but available in XP. Windows 7 also accelerates Cleartype text.
