No. the whole idea of upgrading DirectX is to get more visual effects.
That translates into lower framerates as the graphics card has way more
things to display for the same frame.

I'm not prejudiced. I hate everyone equally.

Well, if the performance degrades that badly, how do you go back?
(Or can you without reloading Windows completely?)

I can't prove this, but what I suspect is that the Dx10 cards
running under XP, run in software only. That would make them
pretty slow, and also force them to cut back on graphics
quality. I have some Dx10 cards coming in for testing,
and I will post on the result. I will compare them to a
7950 GTS. The Dx10 cards are 8600 GTS , and are
suppose to be right much faster than the 7950. However,
I noticed in benchmarks on the web, that the 7950 was
nearly equal or better in most tests under XP. The PC
I will use is one monster of a machine, and with a 7950
in it, AquaMark3D benched at better than 133,000. I'll
have the 8600 mark sometime late next week. If anybody
knows about possible traps in this test, let me know
in a separate post, and we can rant about it there ...
like driver issues.

No, they don't run in software mode. They run in DirectX 9 hardware mode.
There are no features, hardware OR software, of DX10 supported in XP at all.
There is no 'software DX10 mode.'

And, the 8600GTS is not "much faster than the 7950". The 8600's are lower
mid-range cards (even the GTS.) The 7950 should trounce the 8600GTS in
almost any DirectX 9 game. Unfortunately Tom's Hardware doesn't have the
7950GTS nor the 8600GTS in their testing library, but when comparing the
7950GT vs. the 8600GT, the 7950GT varies from 300% to 50% faster in the
1280x1024 resolution game tests I looked at.

If you want a DX10 card right now, only the 8800's are worth it, in my
opinion.

Of course, in my opinion, since nVidia is releasing new cards later this
year.. the best thing to do is wait, especially if you already own a top-end
DX9 card and XP only.

Rats. I kind of figured that. Problem is BFG seems to
have discontinued their 7950, and the company I am
buying from recommended the 8600 as a replacement.
My bosses went with it, and did not ask me. So I'm
still going to bench the 8600, and stick the "slow down"
figures right under their know-it-all noses. I knew that
7950 was the better card. I just don't understand BFG
dropping it ????

I thought Vista had both 9 and 10. DirectX9 games use 9 and DirectX10 games use 10?

I wonder why they didn't ask you - go on have a think it about it?

I think the reason why my 7600GT performs well compared to the high-
end cards might be because it might be accelerated. The manufacturer
produced it for the China's market, and put a huge sink on the card;
maybe they overclocked the card to the smitherens,

That is correct. DX10 games use DX10 IF you have a DX10 card, in Vista,
otherwise DX9.
