New 7990 issues, low performance/tearing

Apology for the new thread, can merge if need be but thought It would be better to create one for this issue.

Would like some help if anyone can please. Having installed my new 7990 I unfortunately don't seem to be having a good experience. Sleeping Dogs seemed to bench ok (think it was max 112, average 85, min 52 with same benchmark settings as the thread) but it feels very choppy\sluggish in game. Skyrim flat out was buggy with crossfire on, with one card it runs fine. Guild Wars 2 with vsync on is choppy slow, only way help that was to enable frame limit and disable vsync but then would get tearing. I also get the occasional crash to desktop and the games hang.

I've ran 3d mark here: http://www.3dmark.com/fs/1221338 , scoring better than 780 so crossfire is working. Tried frame on\off, clean windows install 13.11 9.4 (latest betas), and I'm stumped. I've downloaded 13.10 whql to try tomorrow but doubt it change much.

Going to try more tomorrow but it's looking like a likely return, talk about being letdown at the moment. :( . I'll check back in morning but I'd really appreciate some assistance for this.

Also if you have not met RadeonPro, I would look into taking that small piece of software in from the could and cuddle.
I disable V-sync in all games, and if I get tearing I use RadeonPro with either DFC or DVC (depending on what works best).

Hi Matt, I did see both threads before getting the card. I'll do the after burner stuff as I do have experience with it, I used the 7970 before upgrading to the 7990.

Not to seem like I'm turning away help, but surely installing a custom bios on a brand new stock card shouldn't be a requirement just to run it decently, I'd understand for overclocking but stock?, I'm also hesitant as I might have to return the card and OcUK probably wouldnt accept changes like that?

What was wrong with skyrim...were you using an enb? Theres an issue with vsync at the moment too so i leave it off.

No enb, just updated Skyim and DLC. It's a big no no to turn vsync off in Skyrim as it pretty much hard coded for the game engine, turning it off can make the physics go haywire and cause a lot of other bugs within the game. AMD also has a bug in Skyrim which hasnt been fixed were you get a bad stutter in some locations in first person and the only way to fix it was to cap the fps to 59 and crossfire hated that, it was unplayable. Also texture flicker and bugged shadows would happen even with stock settings on with crossfire. Single card with capped fps the game runs fine.

I'll look into Radeon pro, used it before but didn't really need it. No idea what DFC or DVC stands for sorry :p (first crossfire user) but will look around in the program to see what you mean if can. I'm assuming the crossfire configurations like in CCC.

Appreciate the help so far fellas, I'l report back when tried after burner, new drivers etc.

Its not an essential requirement, but if you want to get the most possible from the card then you should do it. AMD set very conservative limits with the 7990's TDP and PowerTune settings so the card throttles quite easily. Its up to you whether you're happy to put up with that, or do something about it. If you keep it at stock, maybe under volt the card a bit, put the power limit at +20% it won't throttle too badly. Its funny when you look at official reviews and know theres around 5-10% performance missing and its still a long way ahead of everything else.
 
:sigh: Will sometime get a game hard crash to a blank black screen with a flashing minus sign at the top left. I've had it now 3 times in a row after a driver install.

Would install the driver, reboot, when windows loaded it would crash to the blank black screen forcing me to manually reboot, when windows loads it says the amd driver has failed. Would put a clean image in to start from a fresh install and it did the same thing 3 times. I turned the PC off and re did everything again and it worked this time on the driver install, but the crashing will probably persist. Any insight?

Also tried 13.10 whql and the beta 9.2 ,4
 
Still crashed on 9.2 beta driver, screen flickers then the whole screen stayed white, can't alt tab or anything only hard reboot :confused:

Edit: This is with the afterburner changes, gpu usage on both the same, 9.2 seems to have vsync issues on Guild Wars 2 (stuttery), going back to 13.10 whql.

Edit: Trying to install 13.10 whql, everything is fine during install but after rebooting as the driver kicks in for the first time the screen just refreshes then goes blank with a bios looking - flashing top left, other monitor just shuts off. Seems like a complete lottery if the driver install is success.
