DX12 runs notoriously poorly on NVIDIA cards. There's a chance that your games were previously using DX11, but the update changed that to run on DX12, which would account for the loss of performance (NVIDIA only, AMD does great with DX12).
I'd double-check all those settings.
irrc Nvidia card still perform well with DX12 games, just the performance increase over DX11 is not as great as AMD. But most, if not all benchmarks for Nvidia (1080, 1070 and 1060) show DX12/Vulcan/whatever still at least faster than DX11, except for Vulcan Talos, so it may just be a case of driver issue. Unless I misunderstood what you meant by "DX12 runs notoriously poorly on NVIDIA cards"

Well, it's CS GO. It starts with low fps (70-72) until I click the Windows key and get back to game. Then, fps is fine (300+). There is a few seconds freezing when I come back after clicking the Windows key as well. This didn't happen before update.
What about NVIDIA GTX 10xx cards? Are they also bad at utilising DX12? I'm not going to upgrade my GPU soon. I think it's good enough. It is GTX 980.

If it's CS then GTX980 should be more than good enough depending on your resolution and target fps. This case it seems like just driver issue. Or some game profile thingy, may be you can try resetting all the settings and change them afterwards.

All the NVIDIA cards are bad at DX12. For basically every DX12 game, if you have an NVIDIA card you should make sure it's running in DX11 instead. (DX11 will get you better performance on an NVIDIA card in that game).
That said, it's not like the game won't work. It'll just be a little slower. As to your specific problem, I don't play CS:GO or have my Windows key enabled, so I can't help you there  . And sorry if it sounded like I was advocating a new video card. I was not.

CS:GO is not even DX12 anyway, so it doesnt matter.
Anyway, won't get into DX12 discussion as it wont get anywhere and there are not many reliable DX12 benchmark to draw conclusive results.

There's only performance loss on 1 or 2 games w/ poor driver/game support - the API itself is fine.
"DX12 runs badly on nvidia cards" is not correct, "nvidia does not benefit much from async compute" is much more accurate.
Async compute is one feature of dx12. GCN benefits quite a lot from it, Maxwell struggles to benefit at all and Pascal gets a small performance gain, generally. This is usually used to improve GPU-bound performance.
Most of the other features, especially the main flagship feature - the dramatically (as much as 3-5x or more) reduced CPU load - apply to both vendors.

CSGO shouldn't do that, check that you have the nvidia DPC latency hotfix driver. I don't know about any windows 10 specific issues

Hello, I'm considering to slowly upgrade my computer, starting with a better graphics card. I don't intend to OC and I'm hoping to upgrade CPU some time later. I was looking into Radeon rx 480 (I know it will be a bit bottlenecked)..
I use 2 24' monitos (1920x1080). The games I mostly play aren't that demanding but it's starting to show a little. I play Dota 2, GW2, some SC2 and mostly indie stuff.
My specs atm:
i7-950 (@3.07Ghz)
8gm DDR3 RAM
P6T SE (LGA1366)
AMD Radeon HD 6800 Series (ATI)
Chieftec APS850-CB PSU

What is everyone's go-to PC case? (With high performance/overclocking in mind)
I'm starting a new build soon and I'm tired of seeing the same handful of cases everywhere (R5, Enthoo, S340/H440, Obsidian, etc). I know they're popular for a reason, but I guess I'm too hipster for my own good :D

My new build has a Corsair Carbide Clear 600C Full Tower case. I know a lot of people aren't a fan of the inverted design though 
The case does the job though.

it's been a long time since I got a chance to upgrade my computer due to the typical college life but was wondering if someone wouldn't mind helping me out. Here is my current setup that I'm concerned with what I need to upgrade. At the moment I am casually playing Overwatch around 90fps. I just want to increase the fps a bit more with a more up-to-date hardware. My eyes are set on changing the GPU and maybe the CPU.
Motherboard: Biostar TZ68A+
CPU: i5-2500k
GPU: Sapphire Radeon HD 6850
RAM: 2x G-Skill F3 4GB
PSU: 750w (don't know the exact model but I know that I can leave this alone)
What is your budget?
Around $600
What is your resolution?
1920x1080
What are you using it for?
Mostly gaming. Just a casual gamer mostly playing Overwatch at the moment and would love the option of possibly streaming it as well.
What is your upgrade cycle?
This is probably my last cycle of the PC and then after this I will be starting a new tower/comp in the future (~4 years).
When do you plan on building it?
Within the next couple days/weeks.
Do you plan on overclocking?
If I need to.
Do you need an Operating System?
No
Do you plan to add a second GPU for SLI or Crossfire?
Not at the moment.
Where are you buying your parts from?
Newegg preferably but there are local Fry's and MicroCenter stores I can drive to.

Is there one of those for the 7xx series? That sounds exactly like the problem I have, but Googling sounds like it's only for the 10xx series.

Idle DPC latency was improved on all cards. The problem may be much worse for pascal however, especially at load (not sure exactly)
----------
@.kv - A gtx1060 would be a pretty good solo upgrade there, much more FPS on the graphics side and also enables streaming via NVENC.
NVENC h264 encoding doesn't have quality comparable to CPU encoding (needs a lot more bitrate, maybe even around 2x for the same resolution and fps) but it's "free" on performance and doesn't load the CPU.
With upgrading both CPU and GPU it's more $$ but more options open up

Well, I'm not completely sold on it being my problem, but I'm not really sure how to go from having DPC latency stats toward trying things to fix them. Does your response mean that driver download would work on the 7xx series? It looked like a full driver package, and usually those won't even install on the wrong card series.

You can see there are a bunch of things that have slow execution times. Basically when I reboot everything is completely fine. After a period of time, everything starts feeling sluggish where e.g. maximizing a window is no longer snappy and there's a sort of noticeably slow "expanding" effect. I also have FPS loss in games.
This is usually triggered most quickly by opening a bunch of flash streams, but it happens outside of that, too. I tried updating drivers and it was actually much worse, where I had this problem all the time. I rolled back to 365.19. My latest plan was to just keep rolling back drivers trying to find a point where this didn't happen.
I can't really remember when it all started. I want to say it was around the time I RMA'd one of my two video cards and then put in a replacement, and I probably would've done a driver update at that point.

Yes - at least it installs on Maxwell, i think Kepler too. http://www.overclock.net/t/1605618/nv-pascal-latency-issues-hotfix-driver-now-available/
Your Nvidia/dx execution time is very high but your Etron USB controller is also high.
I usually look at the current reading on main page for interrupt to process latency (not the maximum, that's not very useful); also that page that you have open sorted by total execution time after a test period of a few minutes.
Half of the point of having latencymon is that you can see if it's high enough to cause problems, check if the interrupt to process latency is spending much time at high values when you're experiencing issues. 10 is awesome, 100 is ok, 1000 is terrible (rough orders of magnitude)

I'm 1000 on a good day, over 10k on a normal day. Currently bouncing around 1-1.5k, but that's because I rebooted recently. I installed that driver a few hours ago, so I guess we'll see what happens. My hard pagefault resolution time is currently only 2-5k, though. Before reboot I can't remember what it was exactly. It was either 500k or 900k (i.e. almost a full second).

Hello,
I know that this thread is mainly for desktop but i need to buy a laptop that will mainly be use for programming. But i don't really know what i need. At work i have a death machine 'cause i use some really heavy software to move data but in this case it will be mainly for PHP programming. Last laptop i owned was a Dell 800 which was built for Windows 2000 so... i don't know how is the market today :p
So i need something that's correct. Not a monster PC but not a potato either.
What is your budget?
I don't have a budget.
What is your resolution?
Well i don't know if i need 1920 for work. Never worked on a laptop. I uselly don't like it but i kind of have no choice.
I'm torn on the fact that i like to have big screen but i don't want a 19" or something laptop. Cause i want to be apple to transport it easily.
What are you using it for?
PHP coding but i may have to use Talend which is quite heavy.
When do you plan on buying it?
Next month
Where are you buying your parts from?
I prefer Amazon but whatever is in the EU.
Others
- I guess the only thing i do want is the possibility to plug another screen ('cause i know there's some new PC that don't even have a hdmi or display port).
- Don't need a CD/DVD drive.
- Don't need a touch screen.

You should definately fix that then, but it's likely that the GPU driver is only a part of that. Start by disabling all of the CPU power saving stuff for testing, you can look at total execution time etc after a few minutes of a test then

I usually find NVIDIA's application annoying when it notifies about updates, but I'm actually looking for a new driver update because the current one doesn't solve problems with the last Windows 10 update. Unfortunately, NVIDIA doesn't think there is a problem?

Interesting.. but does that design really help at all? The 90° turn of the RV05 (exhaust goes up instead of back) makes more sense to me if you're designing around the "heat rises" concept, but that's just me

It's already all disabled.
