Why is my XFX Radeon HD 7990 performing so slow?

[bzer0b]

Title says it all. I only get about 30-40 FPS in GTA 4 maxed out.. Same for Battlefield 3

My specs:
AMD FX-6300
XFX HD 7990
8GB RAM
ASRock 970 Extreme3 R2.0

It could be a multitude of things ranging for a PSU that can't handle it to an outdated driver, you will need to give more information then what you have given for any genuinely helpful answers.

Heres my full specs: ASRock 970 Extreme3 R2.0
AMD FX-6300 Six Core @ 3.5ghz
XFX Radeon HD 7990
Antec High Current Gamer 850W 80 PLUS Bronze Modular
Kingston HyperX 2x4 1600 8GB
Seagate Barracuda 1TB

The minimum Wattage for the HD 7990 is 750W as stated on the AMD website, i'm still curious why my graphics card is performing slower.

The next thing to do is make sure you have the latest drivers for your parts, I know that games for now are not as optimized for radeon as they are for the GeForce line up but 40 frames for that card does indicate a problem somewhere.

Cpu bottleneck maybe? Try disabling crossfire and see what kind of frame rastes you're getting. Also what is your resolution when playing the games?

I'm playing on 1920x1080 resolution. And also, how do you disable crossfire?

have you tried looking in Catalyst Control Panel? idk about AMD but for nvidia cards there were options for that in nvidia control panel

Sadly there isn't any option for me to disable CrossfireX.

Try disabling it via motherboard bios.

I have the exact same issue man, BF3 seems to be running kinda sluggish I mean some people report getting frames of 120+ but im getting maybe 60-90 fps. Sometimes it might reach further but when I'm staring at the sky or something :/. This is kind of a let down here, I mean the frames shouldn't really be that bad when some people can run GTA4 at 90fps avg.

What's your CPU? I'm not sure if its a bottleneck, but i've decided to upgrade my FX 6300 to the i7 3770(non k) and see how it goes, and yes, i was the one who commented on the GTA 4 Video.

Ok yeah my CPU is the i5-3570k, and its at stock clock of 3.4ghz. I was thinking of OC it maybe or perhaps upgrading to the i7-3770k. You haven't gotten the cpu yet?

I wouldn't think that your CPU would bottleneck your GPU dude, but once i get my i7 3770 i will give you more info if it helps.

Thanks I appreciate it, but Yeah I wouldn't think so either, its just I'm getting super low fps compared to others, actually around the same fps your getting in games. I have a Sapphire 7990 btw.

for gta 4, probably about right, it doesnt run well on even the best hardware. For bf3, OC the fx6300, the 7990 is getting way bottlenecked.

 

[sean stallings]

I'm having the same issue. Recently replaced my HD 6870s for a single 7990.

I don't think it's bottlenecking at the CPU, I *think* that for some reason only one of the processors is being utilized. Either due to bios or drivers. When I look in catalyst control it only shows one GPU, and doesn't even give the option to enable/disable crossfire. This shouldnt be the case if there are 2 GPU's right?

What makes it stranger is that in device manager I can see both GPU's, both have drivers and both are working correctly.

strange issue.

With a 7990 There is no option for disabling crossfire. For all intents and purposes it is a single card; That is how CCC sees it. GTA4 is a horribly bad optimized game, but as for bf3, it should be fine. Start by updating the drivers, and if that doesnt fix it, try the card in another PC or a friends pc if you have that option.

If you cant get it to work and its a newly purchased card, maybe consider exchanging it

This is what I thought aswell When i bought the 7990, I ended up using RadeonPro which helps with crossfire configurations (which is exactly what the 7990 is) I just play around with settings and lock the screen rate at 120hz so my games do not crash. I think Some games just do not agree well with the 7990 and crossfire. I mean I can play Max Payne 3 and Metro Last light, well above 100+ fps and maybe around an average of 80+fps with metro last light. This game looks drop dead gorgeous yet some others like GTA4 made years before MLL runs at 40-60fps tops. Idk what is up to be honest.

So there is no option to disable crossfire for amd dual gpu card? For 690 the option still available just like any other SLI setup.

Ok, I downloaded FurMark and it is seeing 2 GPU's. Was trying to play Rome II but that game has......issues. Tried a couple of other games and it seems to be running great. Just installed it yesterday so still getting used to it.

I've got i7 processors in my machine if that helps with questions about CPU bottle-necking.

I just installed my i7 3770 into my rig and getting about 90 fps average in bf3, and in GTA 4 50-80fps. I think what ffinfinity1 said was right. HD 7990 only works well with some games.. Anyways i kinda have one problem too, when i enter to a game (black ops 2) it buffers?.. (i don't know what word to describe the problem -_-) Well not only with black ops 2, other games too.

Hmmm

hmm didn't you say you had 30-40 fps in GTA4 they seemed to definitely improve a bit. Game might be more CPU reliant than others however. Do you think I should upgrade or not???

I would think the i5 4570k is good enough, but overclock it maybe to 4.5ghz? It would probably help. So my answer is no.

I've 7990 and did have the same issue with slow fps at around 40 in ultra 1920x1200, I did all kinds of stuffs (bios, overdrive, etc, etc) and nothing works until I tried this and I never thought it would work.

go to catalyst control panel > preferences > restore factory default

play bf4 and now I'm getting 104 fps in ultra

the dumbest shit worked

I tried this and still getting 40 fps max :/ When I play alone in the map with a few people I get decent and much higher frames but with 64 players it drops to 40. Not sure what the deal is when of course I have a pretty powerful card. It seems like only one gpu from the 7990 is working or something.
