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?
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?
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?
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.
I uninstalled all ATI items using ATI uninstall tool.
I downloaded the latest drivers and now have ccc version 8.9
I've set the refresh rate of the monitor to 60htz 1024x768 true color (ccc has the same setting)
I've tried vsync in FEAR on and off.
I've tried max setting and min settings.
I decreased the setting in the advanced page of the ccc
Nothing has worked.
Americas army is the only other game I've played and it doesnt suffer the same effect.
The only other game I have installed right now is Amerca's Army but I don't think that's stressing the card very much. I'll see if I can get a demo to test it with. any recommendations or easy dl links?
I work a full time job and photograph weddings on the weekend too so sorry for the delays in replying.
Uhm... FEAR uses an OGL engine (Doom3 actually if i'm not wrong), so Doom3, Quake4 or any OGL based game would do the trick. I think UT3 uses OGL engine too, unless they had to port DX10 to OGL... Anyway, UT2004 also uses OGL and any game based on that engine would do the trick, but that engine is kinda old IMO.
I had the same problem with my HIS4850 and EQ2, triangulations that made the game real interesting to play (not). I tried every driver and suggestion possible with no difference. The game would crash like this after 2 - 30 minutes playing. All other games and tests worked just fine. I fixed the problem by replacing the HIS4850 with a EVGA 9800GT. All is good now.
I suspect a small percent of chips have this problem that can only be fixed by RMA'ing the card.
