My rig:

E8200 3,6Ghz OC
slightly overclocked ATI HD4890 with 3rd party cooler and ATI Catalyst 10.2 drivers
3Gb 1066mhz RAM
MSI P35 mobo
X-Fi Elite Pro soundcard


My problem is that in some areas distant trees are flickering. Redcliffe and Dalish camp are particularly annoying. Sometimes, though rarely, they even cause stretching artifacts not much different from artifacts caused by too much GPU overclocking. This however is definetly not the case, I have played around the clocks already to see if there is a change. Only those distant trees are affected. Game is otherwise playable and gorgeus.

I have also tried to play with -dx9 directX forcing trick and stopped using CPU-Control program. (used to force game to run more evenly between two cores for nice speed increase) Nothing has helped so far.

I do have some 3rd party mods installed, but mostly just face morphs, texture & body replacers, nothing that should affect those distant trees at all, not that I can think off.

Getting this problem myself as well. Hasn't happened until recently, with the dreaded 1.03 patch.

I too have face morphs and hair mods. That's all though.

[MaaZeus]

I am still running on 1.02, so its not a patch thing I guess.

Same. Just got it yesterday in Redcliffe. Two ATI Radeon 4850s in Crossfire (ATI 10.2 drivers), Windows 7, 64-bit OS. Temps are *not* overheating. Nothing in the Catalyst Control center fixed it, including disabling Catalyst AI (one way to break Crossfire). In game, windowed mode did not help, nor did any other setting, except 'Graphic Quality'. Now sliding it down, even from 'Very Good', to 'Good', fixed it for awhile, then it came back. Zoning seemed to help. I've even rezoned back to the same area without issue, so it does seem somewhat random.

I've installed the Release Candidate of Microsoft's .Net Framework 4, updated my PhysX drivers, and reinstalled DirectX, including the Feb. updates. We'll see if the issue persists when I fire it up again.

I also tried CPU-Control, but get the same issue with or without it running. I am also running 'Vanilla', no mods.

Edit: I am running Dragon Age 1.02a, and have never updated to 1.03

I've started getting it periodically in the past few days, it persisted even when I rolled back from 1.03 to 1.02. I notice it's more likely to happen when certain spells/powers are activated - especially mage 'Haste'. Adjusting graphic setting hasn't helped.

What you are referring to sounds like z-fighting, which is a visual anomaly that is present in many games. Its not caused by the latest patch. Its very noticeable looking down onto the Kocari wilds from Ostagar.

Or I could be completely wrong and its a driver problem, which is just as likely

I am still wondering what would be causing it. I have played Dragon Age before couple of months ago, and my rig is largely the same, and everything was perfect then.

It might be just driver issue, but I dont see too many ATI users with 10.2 Catalyst complaining graphic artifacts.

Once I finish my current characters game perhaps I should do reinstall the game, go through the mods and install only what I deem necessary to keep things clean and removing possible culripts. We'll see if the problem persists.

Hey guys! I`ve solved the problem. Just run the game in compatability mode Windows XP (SP2). That is all.

[DABhand]

Menora is your GPU still under warranty? If so maybe play it safe and RTM (return to manufacturer) and explain you were experiencing artefacts.



Sometimes when artefacts start appearing it could mean a problem with the card itself, not always but I think its best to play it safe. And who knows you may get a later equivalent of the card you send back

[Menora89]

No, it is not hardware problem. Another games work properly. In addition I`m not the only person who has this bug. And they in warranty service surely will test the card. Once I`ve already made the thing you advice. But then GPU was really broken. Such way I became the owner of my current GPU

Just because only one game displays issues doesn't mean that you don't have a hardware problem.  It's common for small instabilities and issues to only be triggered by certain operations in a program's code, which one game may use but most other games may not.  The same applies to overclockers - instability can result in errors only in certain programs simply because of the types of things those programs do.  That's why it's beneficial to run stress tests to check for errors - something like Prime95 for your CPU, and something like Furmark for your GPU.

If the standard definition of artifacting is being used by all of the members adding comments here, I have seen only one member knowledgeable enough to also add that his thermal monitoring eliminated GPU overheating.  Anyone actually experiencing classic artifacting should have already obtained and installed a thermal activity logging utility and put it to work. 

nVIDIA products have been running too hot since the Geforce 8n00 cards arrived on the scene three years ago, and those also had faulty fan control routines in the firmware far too frequently, particularly the mobile versions.  (I have Geforce 8800 GT and 9800 GTX cards, and use them, but with alarms set in thermal monitoring, because I just don't trust nVIDIA the way I did from 2000 to 2005, when they screwed everyone over with their nasty FXes).

Nvidia products have been hot so has the 56xx+ families of ATI. Best type of cards to get (that unfortunately take up 2 slots) are the cards with the exhaust extension that piles out the heat from a grill out the back of the case directly, so its seperate from the heat given off by other components inside the case.



They all usually on average in a standard case will goto 70-80°C on full load, that is for both ATI and Nvidia GPU's. With the exhaust option of GPU's, that can go down to 60-70°C on full load.



Obviously it helps the better quality of case you have, they are expensive but to people who love their gaming rigs, a quality case does equal a quality performance.



Both families of GPU's have had their firmware problems, the latest for Nvidia being the 295GTX problems with overheating due to a faulty fan function, but the 5790's for ATI had problems there too.



I notice you have a very anti-Nvidia stance Gorath, not had much luck with Nvidia GPU's? I suppose I can be called to be anti-ATI But not on performance, but prices for a card that does not equal performance on hardware available on an ATI GPU and certainly not worth the extra cost over an Nvidia GPU.



Sure ATI's have lots of streaming processes going, but that means nothing when it forces the GPU and CPU to work overtime for Physx and Cuda emulation. But hey thats me.





To others having problems with DA:O and on a Nvidia GPU, try this what I did to minimise the possibility of artefacts and tearing.



Right click on the desktop > goto Nvidia Control Panel



When open, goto Manage 3D settings, and on the right choose the tab Program Settings.



There you should see a list of software you can change settings for that is currently installed on your system.



Here is what I changed (be aware this is only for 9series upwards)



Anisotropic Filtering - set to off (I know people would want to force a high value here, but DA:O doesnt need it)

Extension Limit - set to on

Maximum Pre-rendered Frames - I set this to 5, it should be at 3 by default, if your not sure, set to 4.

Multi-Display/Mixed-GPU acceleration - set to Single Display Performance Mode

Texture filtering - Anisotropic sample optimization - I set to off

Texture filtering - Negative LOD bias - I set to Allow

Texture filtering - Quality - I set to performance (you can keep at quality if you want)

Texture filtering - Trilinear optimisation - I set to on

Threaded optimization - I set to on

Triple Buffering - I set to on (only do this for 9600+ GPU's)

Texture filtering - Anisotropic filter optimisation - I set to off



For me I always seem to get the best performance that way, and could last a fair bit of time in 1.03 and 1.04 set to that.

For budgetary reasons, I stay a year behind, and take advantage of the depreciation. My newest Radeon is an HD 4850, which doesn't seem at all thermally challenged with a single slot cooling solution, but it's in a CM 590, which is a very well ventilated case.

[DABhand]

Yeah all the GPU's should come with the ventilation/exhaust. Since most GPU's fans take up the lower slot anyway.

[Gorath Alpha]

I have an HD 3870 with a large, two-slot fan shroud cooler that is fairly noisy, an 8800 with a single slot cooler, the 4850 has only the single slot, and the 9800 is an MSI with an odd cooler that extends out into the adjacent slot's space where the fan is located, but only has a single slot bracket.  It runs cool enough, although the 8800 always runs fairly warm, and is the one I sorta "worry" about.
