What are you utilizing that runs DX10? There's only about 5 games on the market that use it, and all of them run 10%-25% faster in XP, using DX9c.
And, Vista is still alongs way from perfect. Even Microsoft admits it.
Example #1:
A FEATURE in Microsoft Vista means that something as small as swapping the video card or updating a device driver can trigger a total Vista deactivation.
According to APC mag, minor upgrades to your desktop will result in your PC will going into "reduced functionality" mode, where you can't do anything but use the web browser for half an hour.
You'll then need to reapply to Microsoft to get a new activation code.
Hack, James Bannan noticed the flaw when he swapped over the graphics card on his Vista Ultimate box. A few days later he got a Windows Activation prompt and had to speak to a Microsoft customer service representative before he got all his functionality back and the feeling in his toes.
Wondering why he got the shut down request, Bannon obtained some tools from Microsoft which listed all the hardware changes on that machine since activation. Vista thought his disk controller had changed, so the graphics card change was the final change which tripped deactivation.
But Bannan had not changed his disk controller, all he had done was upgraded the Intel Matrix Storage Manager application. Vista reported this driver upgrade as a major hardware change event.
It appears that Vista designers had not worked out that if you change device drivers it does not necessarily mean you have changed your hardware. It could be, as in Bannan's case, you have updated or changed the drivers and not the hardware.
This is quite common as some of the drivers which ship with Vista are out of date or not as good as what you can find on the manufacturer's web site.

Example #2, (Vista has memory flaws.)
MICROSOFT'S latest operating system, Vista is running out of memory faster than a politician in a corruption scandal.
According to ZDNet, the 'Out of Memory' error, which is the same as Terry Pratchett's 'out of cheese' error, is seriously stuffing up Vista's file handling.
The problem can be clearly seen when a user tries to copy 16,400 files or smaller groups of files that add up to 16,400 between reboots.
After you get the 'Out of Cheese' message you will also suffer from menus and tabs disappearing within the Windows environment and even reboots and BSODs are reported.
The problem occurs where users are running Kaspersky security products, but it is not the software that is causing the problem. Other software also suffers but it seems that the Kaspersky software shows the error in its full glory.
The kicker is that despite Vole knowing about the problem for months it is not going to be fixed in SP1. Vole is currently offering a hotfix for the problem but you have to ask it nicely.
ZDNet have also found some other file handling problems in Vista when it handles more than 1,500. A quick look at the memory use shows that it is causing serious spiking which does not go away until a reboot.

Example #3, (Business are afraid to touch Vista)
WINDOWS VISTA'S market share in businesses logs barely more users than Windows 98, reports Softpedia.
Released first to its corporate Software Assurance users in November 2006, Windows Vista was touted by Microsoft as primarily aimed at business customers. Vista wasn't released for consumers until January 2007. However, figures gathered and recently released by security vendor SunBelt Software indicate that businesses are staying away from Vista in droves, as opposed to home users who often have had no other choice but to run Vista on a new PC.
Sunbelt logged the client operating systems reported by its CounterSpy Enterprise security monitoring product and used by machines visiting the company's website. Not surprisingly, CounterSpy Enterprise reported that Windows XP came in first with 82.91% market share, followed by Windows 2000 with 14.88%, Windows Server 2003 with 1.83%, and only then Windows Vista with a mere 0.32% market share, just barely more than last place Windows 98 with 0.03%.
Of the machines visiting its website, which SunBelt assumed were primarily home users, Windows XP was still first with 83.90%, followed by Windows Vista with 9.38%, Windows 2000 at 3.59%, Windows Server 2003 with 1.62% and Windows 98 at 1.33%.
These figures look plausible from here, given the conservative tendencies and inertia of business users, and they do seem to show that Windows Vista has so far utterly failed to take hold in corporate settings.

Example #4 (Vista hates me.)
I pre-ordered Vista Ultimate, as for my business, I needed to make sure I was familar with it when working on people's systems.
I tried to install it on my main computer, creating a dual-boot. I could get past the first section of Vista copying the files for installation, but then after the reboot nothing happened. Just a black screen. No HDD activity; nothing. (I even let the computer sit for over 12 hours on the black screen, just to see if maybe something would happen.) I formatted a spare hard drive and took out all of my others trying to install Vista as a single OS on a single HD. Same thing. I removed everything from my PC that wasn't vital and tried installing. (All but 1 stick of Ram, CPU, and a spare PCI S3 video card.) I flashed the bios on my Mobo to the newest version. (Specifically called "Vista Edition" No go. I spent about 4 hours on the phone with Microsoft, whose final solution was to purchase a new PC, even though all of my hardware was listed as Vista Ready.
I finally got Vista to install, by downloading a pirated Dell OEM version, and then using my legal key with it.
And, if you are curious, here's my PC setup. (All name brand, top quality parts. No weird generic components or anything.)
AMD Athlon 64 FX-60
ASUS A8N32-SLI Delux Mobo
2Gb G.Skill PC500 DDR. (3.4.4.
EVGA 8800GTS SC 320mb
Creative Sound Blaster Audigy Platinum
4 Western Digital WD2500KS Sata300 250Gb Hard Drives.
PC Power & Cooling Silencer 750w PSU
I have Vista installed currently as a 2nd boot on my PC. And, since I installed it about 6 months ago, I have used it maybe a total of 4 hours.
