[GTX 1080] GeForce Driver 388.31 has killed gaming performance and seemingly cannot be fixed

post #1 of 38
Thread Starter 
I installed 388.31 today and immediately noticed performance dropped dramatically in AC:Origins and BF1.

I used DDU in safe mode and rolled back to the previous driver (clean install) = no fix.

I then re-downloaded 388.31 from the Nvidia website and re-installed it = no fix.

Can anybody offer any advice? My 1080 now struggles to keep 60 fps on 1440pUltra in BF1 Conquest whereas previously I could use 120% resolution scaling and still never see the frames drop below 60.

AC:Origins framerates have been almost cut in half.

Fire Strike v1.1 scores are also lower now than they were when the card was first installed (Graphics score 20 793 today vs 22 232 3 months ago). The card has never been overclocked.

Sounds like you have some other issue going on. Monitor background tasks/resource usage and see what's causing the issue.

Running the driver here fine, and even if the driver was the issue, uninstalling with DDU/reinstalling would've fixed the issue.

Thanks. Normally I would agree with you however the only thing that has changed was the GPU driver. The GPU seems to be hitting 98-99% in those games but the performance is now terrible.

I've done another clean driver install (388.13) today using DDU and the problem is still there.

Running 3D Mark still reports the lower Graphics score of 20,000-21,000.

Heaven score is 3115 (D3D11 Extreme).

Performance in AC Origins and Battlefield 1 is terrible.

I feel like this driver has somehow broken my GPU or Windows installation in some way but I have no idea how that could have happened. SFC didn't find any integrity problems so I'm at a total loss tbh.

Just an update, I have ran Memtest and it passed all clear. I've also reverted back from my most recent CPU OC profile and it didn't make any difference.

Could a PSU potentially cause this? I had to replace my PSU after my old one failed around 2 months ago. My PC stopped booting with my old PSU approximately 3.5 years after I bought that PSU. It would shut down half way through booting. Replacing the PSU fixed the booting issues immediately.

I went from this:

To this:

Afterburner now reports that my CPU is at 97-99& utilisation in the 2 games I've tested however the performance suggests otherwise. I'm wondering if the PSU is malfunctioning and preventing the GPU from hitting it's full clock speed (should be 1607 MHz on my card).

I'm just scanning my HDD's atm to make sure they're error free but this is really irritating me tbh.

Have you monitored your power draw on your card? Honestly that PSU might be a bit low for your system at 100% usage with OC.

Thanks for your reply. GPU power draw was going to be my next point of call I think. Am I correct in thinking it's this setting in Afterburner that displays GPU power draw?



Tbh, I did wonder if it would be enough when I bought it but I spent a while researching and everything I could find suggested that a decent branded 550w-600w PSU should be enough to run a 1080. It's also weird that it seemed to work 100% fine for around 2 months.

Download Hwinfo64 and run that. Under the 1080 you'll see the actual power draw. The Power in Afterburner only shows you the percent TDP. Not the actual power draw. It will also show you, your cpu draw. So you can kinda see if your hitting the limit or not.

Thanks. So after running AC Origins for around 10 minutes it seems to have peaked at 172.801W power usage on the GPU. Clock speed peaked at 1911MHz which I think is the auto boost mode kicking in (I don't OC the GPU at all).



System seems stable as far as I can tell but the performance in game is awful. Dropping to less than 30 fps on some occasions.

CPU power peaked at around 45W.

Your intuition was correct, it was the PSU. I tested using a 750w Corsair supply today and game performance is back to normal. Thanks so much. smile.gif
