Computer slower after adding 2nd 6950

post #1 of 17
Thread Starter 
First off, framerates are higher now, of course.

However, it seems like games and maps take a bit longer to load and shutdown. It feels almost like I need more ram now? It's those kinds of slowdowns. Windows hitches when I close a game out; it doesn't feel as smooth. From map to menu, from menu to map, alt tabbing isn't in and out, etc.

Anyone else notice this?

So your running the 6950s in crossfire right? Does it seem like its an actual hiccup in the computer or is it a display problem? I've heard people talking about micro-studder under crossfire and certain things tend to look funny.

Aside from that it could simply be a driver issue. I've got the 6870 and they still haven't gotten the drivers 100% for it. When you installed it did you totally wipe the pre-existing drivers and install the new ones, then enable crossfire?

oh and ROLL TIDE ROLL

Crossfire only helps to sell more cards, the rest is completely up to the buyer if he can convince himself that more FPS in fraps actually mean smoother gameplay.

2 6950's, yes.

Maps don't load as quickly.

I initially did not reinstall drivers. Everything worked but I wanted to make sure performance was 100%. I did reinstall shortly thereafter.

I had a 4870x2, and it was pretty smooth. This is, however, is my first dual card experience.

I smell jealousy in there somewhere....

I think you got some issues going on there. I am running crossfire 6950. Although I am not playing any multiplayer game at the moment, I am not experiencing any alt tab issues or slower load times or windows feeling sluggish.

Something does not seem right....

EDIT: what drivers are you using? Can you check CCC and make sure crossfire box is checked? Will you install crossfire profiles (although should not make a difference other than gameplay) just to put that out of the equation? Can you run a synthetic benchmark like heaven 2.1 or 2.5 real quick and see what kind of score you get - just to ensure you are in the ball park.

Did you go from one 6950 to two, or from some other setup?

It's not like it's a dramatic difference. It's just like it's not quite as snappy.

I'm running the latest: 11.4's from late march and 11.3cap#2.

I got 9000 something on 3d11 with 6970 bios but the mem had to be downclocked to 6970 stock(the asus couldn't handle it). Details here

In warhead @ 1080p, settings maxed with 8xAA, I got 50 - 80 fps.
In bfbc2 @ 1080p, I am cranking 120 fps+. I was before, but now I'm doing it with 8xaa.

That's about all I had a chance to try last night.

I went from one 6950 to two 6950. No difference as far as load times and such goes - actually better since I went RAID 0 at the same time. Gameplay is vastly improved. I never could get understand microstutter. Either my eyes cannot register it or I am not experiencing it - either way I am not complaining

9000 something on 3Dmark11 seems pretty good to me.
