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.
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.
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).
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.
Awesome glad to hear it! Yeah 600W system seems a bit low for an OCed system during peaks. Especially since it's bronze, which means it can only sustain that 80% of the 600W for such short periods of time.

I can definitely see your point although previously I had that 650W supply and I used to run an R9 290 and FX-8350 off it, a GPU and CPU which obviously had higher power requirements than what I have now. I think more watts is definitely going to help and provide some nice overhead but also the EVGA PSU I bought two months ago just wasn't particularly good. Looking at the reviews on Amazon and a few other places, they seem to have a fairly high failure rate.
Firestrike scores are still higher with driver 388.13 (22,000's) than they are with 388.32 (21,000's) but I know that 388.32 is supposed to do some pretty new stuff so there could be other reasons for that. Performance in BF1 under 388.32 is what I'd expect anyway (average of 72 fps at 1440p Ultra with a 120% resolution scale).
They're decent cards. I got mine over the summer because I got a good price for my old 1070 during the height of the Ethreum craze. I wouldn't say that it offers a massive advantage over the 1070 at 1440p60 tbh though. I end up using resolution scalers and rendering stuff at 1600-2160p maxed out much of the time.

80% efficiency means it convert 80% of power drawn from the wall. ie at 600 watt load it will draw 750 watts from the wall. how long it can sustain that load depends on the quality of the components; which isn't necessarily dictated by efficiency.
a good 600 watt PSU would be usually fine, those evga B series are junk.
Honestly, that's my hunch as well. I only had a 650W bronze supply before that one and had no problems with it at all, even when using a far more hungry GPU and CPU setup.
It was loud as well even when I was running at nowhere close to full load.
i can attest to the B series being junk. i had a 500W model running a 6850 and locked down sandy bridge i5. it lasted about. 3 months. after which it just refused to even power the motherboard in standby.
corsair on the other hand... i can say are very reliable. i have an original HX750 in a system from around 2008 that still runs perfectly fine.

i was a little surprised that fractal gave up the ghost and since you mention the evga fans running hard; you sure some how those PSUs aren't cooking? they getting some air flow?

The Fractal just started to power itself off after POST. I use this case which includes an enclosure for the PSU, presumably to prevent heat from dissipating straight up to the motherboard. I don't know of any software that can monitor PSU temp though. I don't use the PSU enclosure for anything except the PSU itself.
I've just noticed on this image though that it shows the floor being used for airflow. I think I may have installed the PSU with the top fan facing in the opposite direction.
This article also suggests that this may have been my mistake.
if there is a grill on the bottom then yeah the fan faces down (and avoid putting the case on shag carpet). but really that's pretty negligible. i was wondering more of something blocking the fan or blowing heat on the PSU.

There is a grill on the bottom of the case although I actually never realised that until last night. The case wasn't supplied with any instructions when I bought it. My apartment is pretty much all hard wood floor so there shouldn't be any issues with carpet.
Nothing else is blocking the fan as far as I'm aware and there can't be anything blowing heat straight to the PSU in this case because the PSU is pretty much self-contained.

given what i've seen in the last few gen of titan (X,XP,Xp) owners; a 1K PSU is enough to run SLI on any platform (115*/20**/AM4). those evga g/p/t 2/3 series are great. that leadex design by super flower got season to take notice.

Unless recycling old hardware, nobody should be looking to run SLI these days though, let's be honest.
