Based only off differences with DX 8.0a, and 8.1a, and 8.1b, i'd doubt it.

ER

I can't tell any difference between 8.1b & 9.

There's probably no difference because we don't have a dx9 video card. Anyway, the game looks good enough for me
I was just wondering if someone tried dx9.0a? I tried the download at microsoft, but they only have a web installer and i don't have internet at home. so....
anyone knows of a standalone installer? tks.

I'm running on a reference design GeForce 5800 Ultra.

Something I noticed is that FL seems to stutter under DX9A when it did not under just DX9.

Nothing on the system has changed whatsoever and there are no background processes running on my XP Pro box.

I've not seen any real changes. But alot of times the changes are subtle but good. I am waiting to see how it affects my other games.

I came. I saw. I conquered. And sometimes get conquered.

No difference here, same performance, though granted I've never had the global server issues that this is supposed to fix.
