Performace issues

post #1 of 11
Thread Starter 
Hi, i am concerned about the performance of my rig in certain games if i put settings on ultra on games like shogun 2 and bf3 i get massive fps drops and horrible stuttering. It would usually go from 40-60 solid with everything high to 10-30 with everything on ultra with horrible spikes on bf3, could my small amount of low quality ram be bottle-necking my other components.

Sorry if this is in the wrong place or has already been asked, I'm afraid i don't post very often.

Cheers.

Don't know that much about AMD, but assuming you're talking about your sig rig, I don't think 4 GB of RAM should be a problem.

i wasn't just referring to the amount but also quality and frequency, im not sure of the timing either.

Also it appears the amount is also a problem looking at my memory usage.
So i will probably get an 8gb kit any suggestions In what make, latency and frequency ( if you know what they are)?

A 6870 will NOT play BF3 on Ultra, or at least won't get much more than 30 fps. You need a mix of Ultra / high to get decent (50-60) framerates.

What resolution you trying to play at? Cheap RAM isn't your problem.

Ah i see, about the same for me. Only difference is ultra tortures my card a tiny bit more.

i just turned off v-sync and im getting 50 to 80 on high using 2x mlaa through ccc, be nice if its the same for you.

Thanks for your input.

Yeah, that makes sense. The 5870 is a slightly better card than the 6870. It's supposed to fit in the gap between the 6870 and the 6950.

But yes, I would say that you are getting the frames that you should be.

15-35 fps on ultra 0xAA ??

That's not right, i have a 6950 and i am running maxed out with 0xAA at 1920x1080 and i'm getting 60-70 fps on average with a min of 53-54, 60fps average on caspian with a min of 45fps fighting in a certain bit of the forest.

Sure my cards overclocked but that only adds around 6-7 fps.

EDIT: Nvm, just saw you have the 1gb card and an i7 @ 3.8, still wouldn't think 15fps minimum on ultra would be possible with that setup though :S

It's definently the lack of vRAM that hinders performance at Ultra. Like I said, with a mix of High/Ultra it runs fine, but as soon as I use Ultra Textures / AA it runs low on vRAM, therefore performance suffers.
