Anyone Know?Thanksgreg

>Anyone Know?>>Thanks>>gregAbsolutley not. It is only available with Vista. This is why I think that it's all marketing. FSX will run best on DX10 there are no doubts in my mind and there shouldn't be in anybody else's.

Yeah, Microsoft kind of has us all by the yin-yang in this regard...want DX10? Then you had better be ready to fork out the $$ for Vista.I think that's too bad they are not realeasing the API for WinXP, considering the installed base. I'm not sure if that's a design choice, in that perhaps X10 can't really be ported to XP architecture, or if it is merely an arbitrary decision.I can easily see the WinXP product life cycle going for another 3-4 years...except that for people running games/DX apps, THEY will be the ones who will have no choice but to upgrade their OS, if they want the latest and greatest titles.RhettAMD 3700+ (@2.5 ghz), eVGA 7800GT 256 (94.47), ASUS A8N-E, PC Power 510 SLI, 2 GB Corsair XMS 3-3-3-8, WD 250 gig 7200 rpm SATA2, CoolerMaster Praetorian

It's going to be an expensive upgrade, given the announced costs of Vista. Before I spend that kind of money on new hardware to run the new OS and a bleeding edge graphic card, and the OS itself, I want to be totally convinced that the benefit is there by seeing direct comparisons of FSX running under Vista/DX9 and Vista/DX10 against XP SP2. No huge jump, me no jump :)In fact, to be a fair comparison the XP SP2 box could be upgraded to the same amount as would be spent on just buying Vista. Then we'd have a proper assessment of best-bang-for-the-buck. Allcott

Well, perhaps.http://www.theinquirer.net/default.aspx?article=35110

>Well, perhaps.>>http://www.theinquirer.net/default.aspx?article=35110Ah, darn, you beat me to it! I was just about to post the same link....Yeah, the BIG questions are (which aren't 100% apparent from that article):1) Will it require a DX-10 graphics card to take advantage of the DX9L features and run DX-10 games, or is it simply a compatibility layer / thunking layer so the API calls work?2) What's the performance difference? Will it be that DX10 games running on DX9L on XP end up running better or worse than they will on VISTA's DX10?--2002cbr600f4i

I am going to let other people here be first adopters of DX10/Vista/FSX. Not me.2nd Gen DX10 card for me all the way. Rel date + 6 months AT LEAST with Vista, and that's only IF I can be convinced the benefit will be there.Besides, I'm so tight-fisted with $$ that I will probably set up a lemonade stand in my yard, to make money for upgrading.RhettAMD 3700+ (@2.5 ghz), eVGA 7800GT 256 (94.47), ASUS A8N-E, PC Power 510 SLI, 2 GB Corsair XMS 3-3-3-8, WD 250 gig 7200 rpm SATA2, CoolerMaster Praetorian

Sigh. They got the claim wrong. DX9.0L will be Vista only. http://www.theinquirer.net/default.aspx?article=35140
