I got a new video card & it freezes when games on DirectX10.

My older gpu an hd 6770 1gb was fine with games on dx10 and had some issues on dx11, but new gpu is the opposite. My new gpu is a Sapphire r9 270x oc boost 4 gb, and on dx11 the game is just fine, but if I put it on dx10 the game freeze and ctd. There are a couple of games with this issue, but the main issue is with STALKER Call of Pripyat.

I have reinstalled the amd drivers a couple of times one and it didn't help.

Anyone know of this issue and know of a fix?

My PC set up is...

Dell XPS 8300 (X8300-7008NBK)

CPU: Intel Core i7-2600K 3.4 GHz

Mobo: Dell Intel H67 generic board

GPU: Sapphire R9 270X 4GB

PSU: Rosewill 550W

RAM: 8 GB (generic 1333mhz)

HDD: 2TB (generic Dell brand)

OS: Win 7 64bit Home Premium

Download and run direct x installer to check itself LINK

I ran the download for direct x from that link, and my pc has either a newer or equivalent version according to what it says. So that's not it, and issue continues. Thanks for trying to help.

Must be drivers issue.

I bet newer games don't freeze on you.

Also try to monitor the heat of the CPU and the GPU, this might be the problem (I had freezes with my old 5770 because of too much heat)

Have you tried running the games in Windows compatibility mode? Try using XP SP2 and see if that works. If that doesn't work it could be anything from a motherboard issue, to a driver issue(AMD drivers aren't the greatest) or even a problem with the card itself.

Okay I have read somewhere that R9 270 cards don't use directx 10, is this true? If it is then why is it that way, and why make a graphics card that doesn't support directx 10? As far as I know it supports directx 9. Is there a way to check out the specs of the actual card that I have? Like a website that scans my card or a program that I can download that tells me what the specs of my card?

everything is backwards compatible. Your card has 11, 10, 9, 8, 7, ...etc.

Umm no, because I have tried 4 games that has directx 10 and it won't play them in directx 10, but it will in either directx9 or directx 11(if it has it). The game will freeze and/or crash after I click on directx 10 and save the settings.

Your Power Supply is not powerful enough. The GPU you are running is a powerhog and requires a MINIMUM of 500W PSU. If your other equipment is not power friendly, you will crash your PC when running most games. You probably think that at 550W, you should be fine, but that is not usually true. Your PC should have a minimum of 20% additional wattage available.

The reason DX9 games will run fine, is because of the limits of DX9 being able to push data to your GPU. DX11 is a lot more efficient in pre-processing. DX10 is just terrible. Try running a game like Crysis 3 at very high settings, and you should crash even in DX11.

Edit, did some basic calculations based on your listed equipment (adding a DVD drive and a couple of case fans, and came up with a base wattage load of 519W for your PC at 80% load.

@ghstbstrI want to add to the above, your PSU is 92% efficient, meaning that you only get 506W effective to your system components.

So full of it.... if it can run 9 and 11 but not 10 its not because of the PSU. TC needs to see if his dx is corrupted. His system does not draw 500w+, lol he is lucky to draw 350w at 100% usage.

Drivers problem probably, you must have old versions fucking things up.

Use Display Driver Uninstaller, make a restore point before, run it in Safe Mode as it recommends, then install the latest drivers.

Follow this guide as well.

"DirectX® 11.2"

Your GPU supports this.

Yes there's a way to know the specs of your GPU, just tell us the brand name =) (open the case and look for a name or something)

@PredatorRules:

I have a Sapphire Dual-X R9 270X 4GB OC with Boost.

The strangest thing after reading soo many things on the internet I came across GSC Game World forums with a topic on "Game crashes when i enter the options menu." that some are talking about an update for Microsoft Windows (KB2670838) that causes this issue.

So I found it on my PC and deleted it and dx10 now works on my games.

Now I am happy that it works! Yea!

That update is called the "Evil update" for a reason :p
