I tried everything to stop the random lockups i was experiencing. I disabled the DirectX 11 option in the Steam setup before loading the game and it works now.
Windows 7 64bit
Asus P7H55M-Pro
i5-661 4.1Ghz
Radeon HD 5850 overclocked 820mhz mem 1225
AMD Catalyst 11.8 drivers
DX 11
6GB RAM PC 1333 DDR3
Acer G245H monitor

*UPDATE FROM O/P*

The problem is still not fixed. I experienced a few crashes with DX 11 off although the lockups are far less frequent it is still occuring.

What to do next. Flash Bios for vid card and Mobo ? I think I wont be doing that. Besides my system runs every other game fine, so why take a chance that it will cause problems for just one of my games (DXHR) to work properly, and besides, i can tweak the voltage with MSI any way.

I'll post it here as well:
GPU Crash issues

It has nothing to do with the game or your videodrivers.

After some googling I found out there is an issue with DX11 and the NVIDIA 5xx series (and perhaps other manufacturers as well). The crashes I experienced in DXHR were simular to the ones I had in Crysis 2 with the DX11 update.

The problem is most card have been shipped with a default voltage rate too low to support high demanding DX11 games, causing them to freeze. What you need to do is flash your GPU bios. An update to your bios can be found on the manufacturer's website, mine was MSI who have a handy tool to automaticaly flash your bios to the latest version. I do read some folks who are screwed because the manufacturer hasn't updated the bios yet, and you have to resort to manual tweaking of voltage.

I have just flashed my bios and have not tested yet, but from what I read this should solve the issue for all you NVIDIA GTX 5xx owners out there. Fingers crossed!

Woah dude, you cannot just tell someoine to flash their video card bios, if he wer to flash the thing with the wrong bios or do something wrong in the process , his video card will be bricked, which basicaly means it wwould be garbage.

But i dont think this is an issue with a whole series of cards, cause DX11 works fine for my 2 580's, it might just be a problem with the game, or a few cards out there, or even with some drivers.

But there is no issue with DX11 with my GTX500 series cards, every dx11 game i have tried works perfectly, crysis 2/metro 2033/ etc,


Also for the topic, if you really think the voltage is the issue some of you people are having here and the only way to fix it is by tweaking with the voltage of your cards, well theres simpler ways to do that, best one would be to use overclocking tools to just uppen the voltage a bit, but make sure you know what your doing or you will fry your video card , know its limits first before you do anything to it. Bios flashing i woudnt recommend at all, its to risky if you are not expirienced, you cannot trust automatic bios flashers or whatever, they will most the time flash the wrong thing to your card and theres a chance it will be bricked and destroyed.

I really do not think theres a voltage issue with the GTX500 series cards tho, my cards work perfectly fine.
Also the Tc is using an HD5000 series card from AMD/ATI, so wth?!

There is nothing wrong with flashing a bios as long as you follow the manufacturer's manuals or simply use the automated tools some have available.

And yes, there is an issue with so called stock settings of voltage on some cards which have not been updated with the latest bios. It's simply a bug or incorrect default setting which can only be fixed by updating the actual chipset on the GPU.

There are many posts on the subject:

The MSI bios update also shows a "fix of stability" refering to voltage settings in the version 2,04 which is the one I have just upgraded to:

In other words, don't tell people the problem is not there, because it is, and it requires a flash. I am not saying this will fix ALL DXHR issues for ALL users, but it's certainly part of the problem many users have been experiencing.

I have an ATI card not Nvidia, so I'm not sure your post could apply to me.

The issue with a flash is most manufacturers don't cover it under warranty. The only one that I know that does is EVGA. Even though others allow overclocking it doesn't also include flashing of the graphics BIOS. Unfortunately many people don't look into that stuff... :hmm:

Just seems to be those few cards out there. Every then and now you run into a game that just hates specifically 2 or whatever cards. My 480 overclocked to high hell works great with Deus ex :D
