DirectX 9.0L is also Vista only and was designed to allow older DirectX 9 graphics to be used on Vista machines. DirectX 10 is based upon a totally different driver system and as such is not supposed to be compatible with any version of windows prior to Vista (Although I believe i read somewhere that some guy managed to tweak it to get it working on XP).
I have just cheked the Crysys website and, although it doesnt specifically mention DirectX 9 support, it does say this:
"Crysis' visuals define "state of the art," with full DX10 support and scalable options to deliver solid performance on older machines."
The "scalable options" bit basically means that it will run on DirectX 9 cards but at a lower quality. This is backed up by the fact that all four of the graphics cards listed in the minimum and recomended system specifications above are DirectX 9 cards.
Well I was trying to run the demo on the following Vista 64 Bit, Ultimate edition. E6600 processor, 680i motherboard, 8800GTX graphics, 2GB memory, Creative XFI soundcard.
Long story short, I get a black screen, thats it, nothing else. Basically the demo does not work on Vista 64 bit. I dont have much hopes on the full game working either. Spent a couple of hours trying all the suggested fixes and it didnt improve the black screen.
So better playing XP it may work there just without DX10.
i have played both the multi-player demo and single player and they both run fine on my system vista ultimate 64 bit ,m2n sli delux mb,amd FX62@2.81 ghz, 4 gig ram@800mhz ,asus 8800 gtx, none of which has been over clocked
I play on Vista and also got black screen. Sounds weird but if you tap alt and tab together a few times, it sparks into life. Also sometimes just clicking the mouse or hitting space fires it up. Seems to be a common problem.
ok... just to clarify for you all; This game was initially designed to utilise direct X10 and on this you will get the best results. however it is fully supported with direct X 9 and will also run fine on XP. the main differences with running on XP is there is (when u first load up the game) no choice to use 'very high' settings. however as reported on www.gamespot.com people have adjusted the codes to allow for higher detail settings on XP. which it is very hard to distinguish between these and the vista 'very high' thus XP is not a hindrance if you want to play this game. and as XP is more reliable anyway, all is good :)
The blackness everyone is talking about may be the shaders quality, I'd advise everyone to check their shaders are set to High. I am using XP, Athlon X2 5200+ 2GBs 800mhz RAM, 8600 GTS 512MB, and I can run it at reasonable graphics and FPS (best at a 900 x 600 window though :P)
But generaly I think this is game is good even at low graphics, its just I have had problems with the shaders thats all they need to be high to work.
haha i cant wait to get this....my PC will eat this up :D but i havent installed vista.....for one simple reason.....a lot and i mean...a......LOT!!!!!! of games are not supported on vista....i like to replay old games...so im not gonna install vista until they sort that out,,,,...i will just have to tweak like the rest of you mortals...:(
intel pentium dual core 3.0ghz (x2 :D) ATI radeon HD2400 Pro 1gb hypermemory direct x10
I rather stick to playing it on XP with DX9. XP runs the way I want it to run. Never change a running system and I've seen too many people who have massive problems with Vista (which should not surprise, why the heck does a operating system need some 15 GB HD space? There's something wrong there)
So it won't look like on DX10? Big deal, it's still amazing with DX9, so what? Sorry, a game is NOT reason enough for me to change to a bugged OS.
You obviously are talking about a completely different Vista to the one that I had pre-installed on my laptop that crashes at any given opportunity, never shuts down properly and makes a fuss of everything simple?
Vista hater? No, I don't hate Vista... Vista hates me.
You need to be carefull with all this compatibility stuff. I bought Stalker (a great game which I was enjoying immensly) until a good way in to the game it started crashing for no apparent reason. I downloaded the latest patch and the game crashed every couple of minutes. I emailed the makers only to be told that Stalker and subsequent patches where not at all compatable with Vista, even though it stated on the box that XP was the minimal requirement and it allowed me to play most of the way through. Also, due to the patch being so different from the original game, all my saves were lost. Frustration at the whole situation was intense.
Just be very weary of selling points from the makers with consideration to compatibility. I am using:
Core 2 Duo E6750 2.6 2mb Corsair 667mhz ram 10000rpm HD GeForce 8800 GTS Vista with all the latest drivers.
