Hello,
I have a HD 7850 Sapphire OC that very randomly and sporadically gives me flashing artifacts, and flashing textures. By flashing textures what I mean is that the entire texture of a sprite will very quickly flash with an "aqua" like color. This seems to increase the more load there is in the GPU. So for example running GW 2 which puts a good 80%+ load on some areas causes it randomly every 10 minutes or so. 3D Mark 11 free edition does not cause it. I have seen it very sporadically in Diablo 3 in the form of little white squares in the auction house. Unigine Heaven shows it rarely too, seems a little more frequent if I run it on higher settings.
This artifacts do seem to very with drivers though, I have tried 12.4, 12.6 and 12.8, it seems like 12.8 gives me the less artifacts, but I can still see them (it is hard though they flash fast), additionally ATI released 3 days ago CAPS for Guild Wars that increased peformance, however I am also noticing less artifacts than before, perhaps because the increased performance resulting in less GPU usage?. I have noticed a relationship between GPU usage and amount of artifacts.
I have only owned two cards in my life, the Nvidia 9800 GT that lasted me a good 4 years, and now this one. I am very positive I never ever saw any artifacts on my 9800 GT. What I am wondering is if this flashing sporadic artifacts are something normal in most cards, or if this definitely indicate I should RMA my card. In fact I already have a RMA number from Sapphire valid for 20 days (18 at the time of this posting now). Still debating if card is good or not.
Is there any program I can download to do any artifact testing?. I tried ATI Tool for some reason it will not detect my card...
Other notes my psu is a Seagate 620 W about 5 months old, and my UPS says the max draw under load is only 230 watts. GPU-Z has a max temperature of 60 degrees.
Full system specs:
HD 7850 Saphire OC (Default OC) currently running 12.8 WHQL drivers, CCC has everything at default)
i5 2500 K (Not OC, just turbo enabled to 3.7Ghz)
16 GB Ram Corsair
7200 RPM Hard Drive 6GB/s
ASUS Maximus iV Gene-z/Gen 3 motherboard
Windows 7 Professinal 64 Bit
Here are some screenshots I got by taking a video and the using video editing software to get the frame where it happens, they last <.2 seconds.
See hazy "cloud" envolving city and part of the bridge.
And in Guild Wars 2:
(See light blue flashing in top right corner and left side)
For Guild Wars I will get 1-3 artifacts every 5 minutes, which can be black random artifacts, or textures flickering to white/blueish white for split seconds, this increases if card is under heavy load 80%+, so in towns for example where there are many people around.
(See squares illuminated for absolutely on reason at all), this is the ONLY artifacting/flicker I can reliable reproduce, all other flickers are completely random.
And in Diablo 3:
(See small white squares on second from the bottom line)
