I've started looking into graphics cards and have been wondering whether to go a high end older card or a mid-range newer card.

One factor is the directx support. I had no idea what the difference was until I stumbled across this thread (yes, it's from 2009) that explains and shows the differences very well.

I tried using the ol' search button but didn't find anything explaining the differences.

Here are some pics of the same scene, but under the different versions.

I know it's an old subject and I'm a couple of years behind but I figured it's good to know the differences. DX11 is definitely the way to go.

Windows XP - DX9 ONLY

Windows Vista - DX10 (can be updated to DX11)

Windows 7 - DX11

i would go Dx11 no point going backwards

and something like ati 6870 1gb is pretty cheap nowadays

http://msy.com.au/product.jsp?productId=6837 $229

i can only find 1 Nvidia in a similar price range

http://msy.com.au/product.jsp?productId=7305 $277 GTX560

the 6870 is probably a higher binned 6850. So whilst it may work on most cards, there is potentially a portion that won't work after flashing it. I could be wrong though, cbf researching.

BTW that directx 11 shot seems to be showing off tesselation more than anything ;)

Well apparently that's what dx11 is all about. It's basically dx10 but with completely revamped tesselation properties.

I think instead of having multiple levels/layers of models, they have only two. Dx10 and earlier would have the lowest detailed model up close covered by the next level, covered again by another level and so on; therefore all levels are loaded for up close models even though we only see the last level/layer. Dx11 on the other hand will only load the highest detailed model close up until a certain distance and then change to the low detailed model.

6850 is same as a 6870, with minor diffs, but you reflash bios and it works 100%, out of the 30-40ish ppl i know on the overclocking forums, all their cards work fine :)

DO IT!!!

i for one, just bought the gtx570 which just kicks pure assssss!!!

in dx11 that road is retarded, theres no way anyone could walk on that without twisting an ankle

Haha. Fk driving on it too. Stiff suspension + road like that = fkd spine; and forget it if your busting for a piss.

Hey guys,

I just installed a genuine copy of Windows 7 64-bit Home Premium.

I am not sure if my operating system is now running Direct X 11. How can I tell or where do I search in Windows 7 to find if it is?

My PC specs are as follows (if its of any importance) -

  • Intel Quad Core 3.2ghz
  • 4.0gb 1333mhz ram (yes I know that's sh!t, i'm upgrading to 12gb 2000mhz soon!)
  • Gigabyte 1gb graphics card (can't remember the exact model name, paid about $300 for it just over 12months ago)
  • Asus mother-board (once again can't remember specs etc)

My PC runs games such a COD: Black Cocks & Battlefield: Bad Company 2 one maximum graphics and runs both of them smooooooooth as silk, both in singleplayer & multiplayer. WoW runs perfectly smooth, you get the idea.

I'm pretty sure my graphics card is an ATI Radeon HD 4850.

It seems to perform very well, and when i had XP and the Catalyst Control Centre installed, i overclocked it and it still ran fine and didnt overheat etc

    • Does that German restaurant still exist in the old place out the NW end of Goulburn? When I say "out the NW end of"...I am really being vague. It was 1997 when I was last there, and the only point of reference I can recall is that it was on the opposite side of the main drag from the big merino. And when I say "opposite side of the main drag", I don't mean "on the main drag". It was either a couple of streets back from there, or might have even been out in the sticks a bit further. Was an old farm building or mill or somesuch. And when I say "the big merino" I might actually be thinking of a completely different part of town, because I just looked on maps and the big bugger is not where I remembered him to be! The food was good, consisting largely of various German mystery-meat sausage/loaf things and kartofflen.
    • So while the second sentence is completely correct and the whole point of the conversation, the first sentence bears consideration. If this bloke is just hoping to throw big turbos on and drive it around, because there are no helpful facilities at all in his tropical paradise** then he likely has zero chance of even knowing what the TP is on the last column in the stock maps, let alone know whether the ECU is operating anywhere near it or past it. So the point is very very moot. And, per what I said before, at stock boost on those turbos, you may well be off the end of the map. **I'm just back from Vanuatu, so I know exactly what small Pacific nations can be like wrt paradise without requisite facilities. But it's not even that simple. I put a high flow on my car and had to drive it around with a proper tune because of the lack of opportunity*** to put the bigger AFM and injectors into it to allow it to be tuned. I had to turn the boost down to less than I had before, and back off the boost controller's ramp, because it was exploring parts of the map that it didn't drive in before, and really couldn't access for tuning on the dyno either, and so was pinging. It was still well within the last column, because when I first**** set up the Nistune on the Neo I rescaled all axes of the maps to give some more space to explore. ***Family dyno was broken ****This was 13 years ago, and the TIM thing wasn't a thing then and so TP would definitely grow when pushing past the stock tune's limits.
    • Yep, this bit another local owner. I caught it before putting the transmission back into the car, what I noticed was the pressure plate fingers weren't flat and even. It's more obvious with the pull style clutch because the throwout bearing ring was visibly not flat once everything is put together. Nismo should really update their instructions to call out this specific detail. I'm not even sure the clutch as-shipped orients everything properly.
    • It ended up being that orientation of the float hub in relation to the clutch disk, when I installed it, I heard a loud click and being stupid, I decided to not take it a part and check it. The hub didn't properly align with the clutch disk and was causing the issue. Definitely an odd one! Dahtone Racing was able to fix me right up, stand up blokes!      
    • Right, but I'm saying on the stock ECU measured airmass from the MAF is no higher than stock. So it's accounting for the higher flow rate iso-manifold pressure. You just have to keep turning down the boost until you're within the stock tune's load scale. If you run off the end there's no telling what will happen. This does mean there's zero benefit to the turbos you're running vs stock, if anything it's just a straight downgrade because the transient response is worse, you don't even get the ECU's boost solenoid helping to pull the wastegate closed during initial spool, and peak power is only whatever the factory map can give you before you hit the R&R corner. On a -9 I would bet that you would have to change out the wastegate spring once you have a real ECU and you're tuning it for real. I'm not saying this is a remotely ideal state of affairs, it's just a way to keep it driveable until you can get a proper tune done.
