FPS drops over time

cian duggan · Dec 22, 2013

As title says my fps drops the longer i play a game

GTX 770 2GB
I7-3770K @ 3.9 GHZ (cooled by H80i)
8 gigs of ram
Windows 8.1

you lads know anything about this

I suspect your graphics card is down-clocking due to heat.

Run GPU Z while you play a game and the check the highest temperature you reached.

You can use afterburner to set a custom fan profile to try and prevent the card from reaching temps that cause it to dial back. Afterburner can also change the temp at which the down-clocking takes place.

Shit its in the 70 degrees what should i do :c

Heat is likely your problem. If you have the space in your computer add some case fans to help promote better airflow.

Ive just spent money on a water cooler theres no way i can afford more fans

cian duggan :

Check the thermal paste on the waterblock then.

cian duggan · Dec 22, 2013

No its not the water cooler idle at 20-30 degrees while it used to be 40 degrees on idle i just want to know how should i fix the high temps on my GPU

Well i have just used corsair link and put my GTX 770 speed at maximum speed

Custom fan curve, increase power limit, and maybe bump max temp to 85.

Ok how would I do this

cian duggan · Dec 23, 2013

ive just increased my fan speed by +70 on msi im now on 25-29 on idle

cian duggan · Dec 23, 2013

Ok so i have been using GPU temp (only problem is i have to alt+tab to check temps) but im geting in the 50's

Z1NONLY · Dec 23, 2013

Run gpuz while gaming. Then come back and check you max temp after you are done playing the game. Also, I dont understand wbat you mean by +70 for your fan speed. Did you set your fan to max out at 70 gegrees?

70c is normal for a graphics card and shouldn't be lowering your fps.

I mean I have a 660, and it hits 70-80 playing graphic intensive games, but I have no problems. I can turn the fan up so it hovers around 60 but then it sounds like a plane taking off

my gtx 760 has no FPS drops @ 80. Might wanna check something else because i really do not think its your GPU card. unless it handles high temps real bad. Did you overclock it by any chance?

Z1NONLY · Dec 23, 2013

These cards have a few different "triggers" that will cause it to downclock. They will back off to avoid going over temp as well as their tdp. They dont wait until the get to 80c they start backing cown before that toensure they stay under their preset limits. Those limits can be increased. My 780 automatically downclocked well before 80c...that was before iincreased the temp limit to 85 and the power to 106%. I also use a fan profile that keeps the card around 70c. The card never gats anywhere any of its limts so it never downclocks under load.
