Going to keep this short and simple (since on other forums, too much information causes people to disregard the problem):
Gigabyte UD3R X58A socket 1366
i7 920 2.8ghz overclocked to a 3.4ghz
HIS Radeon 7850 IceQ X (that I OC'd)
6GB Kingston RAM
2 OCZ 80GB SSD
1 300GB Segate Barracuda 7200rpms
1200w Thortech PSU (totally overkill, I know)
I just got the 7850 and it's not performing very well. Frame rates drop drastically to unplayable levels if I bring AA up to 4x or above.
The questions I have are:
1.) Should I leave the settings in the CCC to "Use Application Settings" and then change the settings in the games I play?
2.) Should I increase the voltage on the GPU if I am overclocking it?
3.) What could cause anti-aliasing to not work?
4.) Do I have a bottleneck someplace? (seems highly unlikely)
I will state that I upgraded from a 5850. On another forum I'm being told that the 7850 wasn't a worthy upgrade from a 5850 and I would see only a tiny performance increase. I don't care about that.[\b] This was one of the best cards I could get in my price range ($250). It was suggested that I get a GTX 480, mod it with some aftermarket hs/fans, and then OC it. I didn't want to deal with aftermarket hs/fans, so I just went with the 7850.
Hopefully I can get some more help out of you guys as opposed to "hurp durp 7850 not gud upgradez from 5850".
Your New card is definately a good upgrade.Please mention why you think its performing poorly.Have you done any benchmarks and compared it to any benchmarks of that same card in a review or something ?Also Mention the Resolution you have been Playing games at and which games.
I'm playing games a 1920 x 1080 over HDMI on a Hanns-G 27" monitor that I'm in love with.
I am comparing it, unfortunately, to the performance i was getting out of my 5850. I could have the settings almost at the highest possible in just about any game and get great quality and performance. I would push 50fps, and the quality would be great.
What I'm seeing now is really poor quality just to get 50fps out of the card. And if I bring any settings up (either in the game or CCC) the fps drops dramatically (to about 15) and the quality doesn't really even look that good.
I took a few screen shots in Dragon Age II of what's happening, but I don't have access to them at this time. I might be able to post them when I get home.
I have yet to run futuremark or anything of that nature.
As someone suggested, Do a complete driver wipe. Using DriverSweeper or so, Especially since you played around with CCC Settings. I had a feeling my card was underperforming when I bot my 6870 a year and half ago, Turned out my HEXA core 2.8 CPU was the bottleneck. Yours seems fine. Best way to check is Run 3DMark and compare with a Review done here. I'd also suggest taking you CPU clocks to stock and checking, Probabbly a bad(wrongly done) overclock.
