770 slight performance drop?

[se_vietboi]

Anyone have an idea why this is happening?

Running benchmarks like MetroLL and 3dmark 11 would yield results on average of:

58.3FPS
11900

Now its at
57FPS
11700

Heaven and Valley has dropped too. Clocks and drivers were untouched. I dropped clocks down to same speeds as my other 770 and it was still slightly slower. GPU activity maxes out at 99% but is a bit jittery.

summer heat throttling boost clocks slightly?

but then you have lighting and mine has never gone above 78c in SLI for the top card no matter the ambient

the fan speed just compensates

As said above it is probably the warmer weather, but also remember the extra heat has an effect on the rest of the system too like the mobo and CPU making your rig slightly less efficient.

Wait for cooler weather then go for it, by then NVidia may have come up with some more GPU friendly drivers too.

I am two days old into GTX70 first ever Nvidia card, I am using the 320.49 drivers and to me every game just runs so sweet and smooth, So what problems are there with Nvidia drivers?

The 320.xx family of drivers have not been NVidia's best, having said that 320.49 seem to be a bit better than the other 320.xx drivers.

People have reported their cards dying using 320.18 (usually older cards), some people are having problems with certain games, me I find the 320.xx drivers a little unstable when benching with several cards and I also find them a little buggy when browsing the web (320.18 and below).

If you have a 7 series card, 320.49 should at worst be usable and at best as you are finding, fine.

320.49 is good for running benchmarks on a single card, have you had a go at the Heaven 4 bench yet.

The thing is that I can clock the card further which heats it up more but still delivers more FPS so I doubt its throttling. That and besides I tested it during the night at 4am when it was colder. Temps never go above 66c. If its a driver issue how can performance differ whilst being on the same one. I've been monitoring boost clocks and its definitely not throttled.

There is a difference between throttling and running warmer, most computer parts will run better the cooler they are even though the differences might be tiny, throttling on the other hand is something controlled by your cards bios.

Before I watercooled my GPUs none of my cards throttled due to me keeping the fan profile high enough to prevent it, now the GPUs are under water they give even more performance as they are running a lot cooler.

I find the best time to test something on a PC is as soon as possible after it has started up first thing in the morning, before everything has had a change to heat up.

Thanks for your knowledge. I've ramped up the fan profile and MetroLL shot up to 60.81. Great stuff.

Edit: Nope I had the res incorrectly set to 1080p instead of 1200p.

is it really anything to worry about anyway you lost 1.3 fps in metro

not the end of the world

and 200 less on 3dmark is insignificant anything can cause that

if you run 3d mark back to back one result might be 100-200 less or 100-200 more than the previous one

it means nothing.

i bet if you compare the results the actual FPS numbers are the same or there will be 1fps different at most

 

[se_vietboi]

The performance drop is insignificant but it might underlie a more serious problem with the card because I see no reason for this to happen other than some sort of defect.

1-2fps is all within margin of error

a background task in windows can cause that

worry when its 6-10fps+
