Hi everyone i just got 2 AMD Radeon HD 7870 each of them is 2 GB am thinking for my first time ever doing a cross fire thing . I am currently running I7 Extreme Version with sandy bridge i get 5.3 GHZ overclocking . So my question is any idea of FPS i will get an how about the graphic as for fsx ? Does it do any improvement as for graphic an such on ?

Two video cards will do nothing to improve FSX performance. Fsx will only use one GPU.

Ok how about one of those graphic card. By the way i didn't buy both of them just for fsx i have other games that i want to tested out . But i am wondering what kinds of improvement would one of those graphic card do to fsx . As for the GHz the I7 extreme does its thing . An the performance its great . So far as i tested it . But for graphic havent tested it yet. I was scared to overclock my desktop then as i open it i figure out something it has this kind of liqued tube inside of it that when the air from the fan hits it . Its like drinking warm water after eating something minty or something . I was always wondering if i was doing this overclocking thing right . Because on all the search i have done it tells me my desktop temprature may raise , but so far its normal actually it gets more colder . By the way i have costum build computer the person who build it for me he is testing some new technology on my desktop. So i don't know my destop full capability . :(

Somewhat true but not totally, but mostly true / And not true

 

Two video cards will give you more overhead to run high levels of SSAA without hitting the 100% load mark on your GPU which causes stutters.. ie: 8X/16x SSAA.. But 16X SSAA isn't going to be a very noticeable difference from 8X SSAA anyway and one 7870 can handle 8X SSAA.

 

If you just create a profile to run AFR it will run just fine. Drawback: V key screenshots stand an 80% chance of not rendering and just be black.. You are more likely to increase the likelyhood of the random black flashing textures.. Microstutter associated with the AFR Method that has to be used as your Crossfire method. I myself stopped using Crossfire as it just isn't worth all the drawbacks. My 6990 handles what I need it to do just fine on a single GPU

 

Anyway just to show, Crossfire does work. I set 16X SSAA for this.. Even in Crossfire my GPU cores are nipping at the 100% load mark just sitting there.

Bill, did your crossfire work like that in the VC of planes with glass cockpits?

Yep..

 

 

Yep..

 

 

 

What I see there is both cards below 40% usage :/

That's 8X SSAA and not 16X SSAA that's why..

Does it go past 50% with 16x? can you please post a screenshot?

It depends where you're at but when gauging stuff like this I always tend to base my findings off the higher end of the hits.. Sure some places 16X SSAA can only be 50% on each core but to me that's irrelvant if somewhere else it's going to get close to, or hit 100% load and start stuttering and skipping frames.

 

 

Thanks Bill, might be an nVidia thing then.

Is that DX9 or DX10?

You are welcome. :) It is DX9

Can I pester you a bit more and ask you to try with the default 737 Bill? Just to be 100% positive

I think we should make an FSMark11 for GPU's - SGSS (nVidia) and SSAA (AMD)

No problem. :)

 

16X SSAA
