r9 390 not performing

RyanoKid · Dec 22, 2015

Hi all

PC specs:

CPU: i5 6500
RAM: 8gb 1600mhz hyperx ddr3
PSU: XFX TS 650w

My msi r9 390 seems to not performing on par with benchmarks. For example im getting 10-25 fps less. Cant run gta, witcher 3, fallout 4 on ultra all dipping down to 30s on 1080p. This system is only new and worrys me a bit spending this much money on a machine that performs less on average

I went to play swotor and the thing was hitting mid 20 fps. and arma 3 is unplayable low 20s up to 60s in cases

My sysem is running at high performance and i have messed around with shadows,godrays, AA etc but unsure what else i can do

I bought this system as i thought it would blow 1080p gaming out the window

Are you running the latest drivers?

RyanoKid · Dec 22, 2015

jimmysmitty :

newest crimson drivers yes

jimmysmitty · Dec 22, 2015

Have you tried the betas? 15.11.1?

RyanoKid · Dec 22, 2015

No I have not tried the beta version yet would that really cause the card to perform that bad ??

jimmysmitty · Dec 22, 2015

The official Crimsons did have an issue where the fan speed was stuck at 20% and if the GPU is throttling then it would under perform. A R9 390 should be able to max out GTA V at 1080P, I was able to get close to ultra on a HD 7970GHz.

Try the 15.11.1 betas.

Thanks for the info. Like I can between 60-30 but mostly at the lower end of the fps scale

The R9 290 at 2560x1600 on very high settings is sitting near 60FPS average. Your R9 390 is a bit faster so you should be sitting at 60FPS maxed at 1080P.

I have upgraded to the new drivers with no luck..

Games seem to stutter also maybe a bad card

Are you sure you are running it in a 16x slot? You diddnt post your motherboard so im not sure what your layout is, but on mine, one of my pci express slots only runs at 4x.

right click desktop > amd radeon settings >

gaming > global settings > global overdrive

make sure nothing is set to negative numbers

set power limit to 25%

set core speed to 0%

RyanoKid · Dec 24, 2015

I will try the amd settings when I get home my motherboard is

Gigabyte b150 d3h ddr3

Thank you very very much dude this had me hovering around the 60 fps a lot more then usual I increased the power liimt to +25% and it has greatly improved performance.

Should I increase it a bit more to make sure its more stable or just leave it?

RyanoKid :

slowly raise it, you can up it by 5% at a time

run a benchmark like valley or heaven, if temps stay under 90 degrees under load after running it all the way thru

then increase 5% more and run the bench again

ideally you want to stay at mid 80's under full load on a 390

also for fallout 4 specifically you want to override tessellation levels, set to 8x at max

you can do so under global settings

Ok the problem seems not to be fixed,

But I think I have the gpu in a PCI x4 slot

Should i change it to the x16?

yes if you have it in a 4x slot you are limiting its performance
