Why do I get low fps

[shnuhh]

Hello,

I have a Radeon HD 7990 and am wondering am I not getting as high of an fps as people on the internet because of my 60 hz monitor? (at times, I barely get 60 fps)

My specs:
FX-8350
Asetek 570lx (w/240mm radiator)
Gigabyte 970a-ds3p mobo
16gb ram
800w psu

I tried reinstalling drivers, reinstalling windows, updating to newest non-beta drivers, to no avail. Could it be because I have a cheap mobo? A faulty card? All gpu temps are normal (75 degrees on full load). Currently, I am running amd catalyst 13.12. I was surprised to find that there is no crossfireX option in it. Any help is greatly appreciated

monitor has nothing to do with the fps produced by gpu. Have you updated your drivers?

what game are you playing?

If you have v-sync enable it will keep the FPS at 60. V-sync helps stop problems like screen tearing which can happen when the fps exceeds the monitors refresh rate.

For some reason it didn't post everything I wrote. but yes, i updated to catalyst 13.12

Whenever i turn VSync on, (for some games) fps becomes very crappy

what game are you playing?

Assassins creed 1-4, skyrim, far cry 3, saints row 4

 

[Entomber]

and which games are giving you FPS issues?

AC4 is very graphically demanding, with just the graphics card you have you can't expect to get 60fps constantly on high settings.

The bigger problem I have is that sometimes the fps drops to 7 and suddenly catalyst crashes or the whole computer freezes

What are the temps on the 7990 like? it could be overheating. Has this recently started happening? or was it always slow?

 

[bignastyid]

Whats the make and model of that 800w PSU? If not deliver good stable power it can cause performance issues.

OP is running an Xtremegear 800W PSU. It's a ticking time bomb and starving his 7990. He has posted multiple threads about this but does not accept that he should spend money on a descent PSU.

it is barely even hot. (75 max). For some reason, i cant use the 2nd gpu, and it shows up as a disabled adapter on catalyst. This issue happened ever since I started using the computer

Yep that could definitely be causing a problem.

I found the EVGA SuperNOVA 750G2 80 Plus Gold Certified ATX12V/EPS12V 750W Power Supply. Is it good?

Ok i will go ahead and buy it, but I dont think the disabled adapter problem I have will be magically solved by a new PSU

Even if it doesn't, it is peace of mind.

You should probably spend some money now on a decent power supply or spend alot more when the PSU inevitable dies and kills the whole system. The 2nd GPU is probably disabled do to a of a lack of power or a lack of stable power. It's also possible the card has been damaged from getting bad power. Cheap PSU's are notorious for damaging other components.

Thanks for your help, but do you know a solution for the disabled adapter problem, or are you going to tell me to buy a 780 ti or something (jk)

It is a power saving feature. Try disabling ULPS (google that)

It was one of the first things I did (regedit , enableULPS = 0)

It's called zero core. It's a new feature on the GCN cards. I haven't had a crossfire rig since VLIW5, so I can't really help you with that.

I get that, but the 2nd gpu always has 0% usage, and why dont I have choice of turning crossfireX on or off. Or did AMD remove that feature

Is it zero usage in every application? Are you running full screen or windowed mode?
