2 4850's not good enough?

[aberchonbie]

So I bought modern warfare 2 today..

I've run into a problem where I'm not getting enough framerates.. it gets really laggy and unplayable..

I have two ATI 4850's (512mb versions) in Crossfire (Crossfire is checked off in CCC) running on a 1920x1080 resolution monitor.

Now, I set AA to 2x and set details to normal, not high nor extra.. (options are low, normal, high, extra).. I downloaded fraps to see my framerates and I was getting around 20 fps..

Are my 4850's not good enough anymore!? I know they're not bottlenecked by the motherboard cuz it's got a x38 nb chipset.. I don't think it's my cpu q6600 at 3.0 currently.. and it's def not ram (8gb @ 800, 5-4-4-18).. I'm thinking it's the graphics cards..

What are your opinions on this?

What game is running that slow? Some games do not support AA and will crash or run very slowly if it is enabled.

By checked off you mean that it is ticked or not? If not, then there is one of your problems...

There was a problem with my PSU.. had 6-pin pci-e connector pulling all from one rail out of four.. spread it out and got sufficient power going to both graphics cards..

Now I see CrossfireX and it's all dandy (unfortunately, i had already reformatted and done everything until i found this out)

Runs modern warfare 2 at 1920x1080 with AA and pretty high details like a champ! no lag whatsoever.. 2 4850's 512mb are more than enough to play at this resolution.

Good to hear you fixed your issue, and thanks for adding to the archive by telling us how.
