I've just put a HD4850 in my PC it's a Q6600 in P35 mobo and corsair 650W PSU with 2GB corsair RAM.

After a few minutes playing FEAR the image deteriorates to this, (note the black triangles and crosshatching lines). This is not part of the FEAR gameplay! Game settings were auto detected by the game, mostly medium.

Normal PC use is fine.



Ever seen this before or any ideas what's causing this, is the card bad, overheating something else?

Lets see here:

Fresh install of drivers?

What are your temps?

Wait...you're using a Q6600 and a 4850, and the game autodetected that you should run at medium? Something isn't right...and hopefully, it's drivers.

I would think it is drivers. You mentioned that you just put it in so did you have a card in there before? Make sure to not just reinstall your drivers but clean out any old ones that are floating around from your previous graphic cards. See if that will help at all.

Is it only FEAR that does it? What diver version are you on?

Adjust settings yourself, and turn on some AA

I should point out I'm a bit of a noob, I never used to be but things have moved on since I wasn't a noob. That make's no sense :\ anyway....

How would I check the temps?

I thought medium for fear was a little low considering the hardware.

I did have another graphics card in there and thought I had cleared out the drivers so will double check. If I have time I'll fresh install XP to be sure.

I tried America's army for a short while before installing FEAR and didn't notice anything wrong.

Will check the driver version and let you know.

>Turn on some AA

I was with you all the way up to AA.

AA is anti-aliasing, it's found in the graphic settings of mostly any game you play. it smooths out the rough edges of objects in the game, so the overall eye candy is much smoother/easier on the eyes i guess.

but i dunno why turning it up in this scenario would help, i'm also guessing its a driver issue, are u updated to catalyst 8.9 yet?

AH OK, I'm photoshop friendly I'm aware of anti-aliasing. Don't think I've had a PC that took much advantage of it before now though. I'll be nice to see it in action.

I'm at work right now, (US Mtn time zone) will check when I get home and let you know.

Did you have a different card in that system previously, and if so did you uninstall the drivers to your previous card? What exactly are your system specs?

I did have another graphics card in there and thought I had cleared out the drivers so will double check. If I have time I'll fresh install XP to be sure.

turn vsync off.

I think you might be onto something there

Unraveling the mystery of VSYNC

Certainly look like flashing polygons to me.

Only a few more hours before I get to go home. I had to take an extra long lunch to buy the wife a car so stuck here for longer tonight. I'll report back.

Thanks for all the advice.

So turning off vsync in the game made no difference.

Catalyst is now the latest version 8.9, still the same problem.

GPU Temp varies from 48 at 0%use to 78 at 98%use.

I couldn't find any evidence of old drivers. I suppose a reinstall is called for to be sure?

Try under clocking your card. You can do it through the CCC. If it still does it the card is probably no good. Still under warranty ?

OMG, Tesselation attacks on normal people! HIDE!!!!

...

No, seriously, crank up the details to high and very high without hesitation. I run FEAR with all max'ed out in my A64 with no sweat. Could be handling shadows the problem, remember it's a OGL based game.

And yeah, it could be the drivers. I have 8.8 and i don't have any issues on XP 32Bits.

Esop!

I only bought the card a few days ago so returning should be no problem. Getting a replacement might be there on special at BestBuy

To underclock do I just pull both sliders down in Catalyst?

BTW I should say I have a CRT monitor at 60Htz, which is why the vsync solution looked so promising.
