If they insist then what is an Nvidia user to do.Long as it doesn't cause stability issues.
If that will ever happen, then I'll be using the last nonGFE drivers for a LONG time... Or maybe it's time for 3rd party tools like ProfileInspector.
Luckily I change only profile settings, so I will be comfortable with ProfileInspector.
You should really not trust anything siriq says about what NV do or will do. Chances are that he was asleep when he was reading this.
I noticed today that I have very high kernel timer latency on my system.
I suspect that the latest nVidia drivers are causing it. I noticed this behavior on 378.78 and 378.92 drivers.
Could anyone check kernel timer latency on their system using LatencyMon?
When IDLE at desktop the first bar (current kernel timer latency) should oscillate from 10 us to 100 us. It may occasionally jump to about 1000 us, therefore the second bar in the same conditions should be 1000 us.
Right now I'm observing about 12000 us latency and is constant. I use Windows 8.1 x64.
I think Nvidia should of RELEASE the tech to EVERY GPU MAKER or made a standard Vsync issue are widely know and effect everyone, instead they took profit now road, instead of the long game which would more profitable even it if took longer. Gsync is still to expensive and probably still to expensive cause there not selling as may Gysnc monitors as they hoped they would.
I refuse to do anything with Vsync cause to me the tearing is worse then the slight latency it cause. That at this point I have compensated for, except in the few games that done so baddy the fps drops to unplayable levels which amplifies the latency issue
Why is he still going on about DX12 not be support on his card or some other non sense?
Thanks for the comment, i can quote you once IT sites going to publish the same info what i wrote
I dont think is a good comparison because I'm on win7x64 (Nvidia driver 378.78) but here no issues
Sorry but on win10x64 I'm still on 375.rel
I suspect that only programmers of Resplendence Software know what is this kernel timer latency. I do not. ISR and DPC - I know what are these.
Don`t forget that 12000 microseconds is not that big value. It is only 12 milliseconds.
Your guys' expertise on the side, for the less in detail feedback, driver seems fine for me, after getting it to install properly I haven't come across any issues (win10, only dx11).
Thanks, for checking this out. That was really helpful. It might be my system specific issue. I'm gonna look more closely to other background apps.
I don't have full understading what the kernel timer latency affects. From what I googled it might affect interrupts handling by kernel, as well as events and sheduled jobs. It is unclear to me if it affects every system call or only those that wait to be wake up. Anyway 12 ms delay in kernel space seems very high, especially when PC is idle.
If you found some descriptions of that kernel timer latency then share. Many gurus would be interested to read (I assume).
Agree, so far no real issues yet.
These are also the fastest in dx11 single threaded and multi threaded scenarios from literally all drivers since 347.xx, so far 353.49 were the best, and now 378.92.
Ok at least according to dx api overhead @ 4.6ghz instead of 4.7ghz
Sure, feel free to do that. Just make sure that these "IT sites" will actually publish exactly what you've wrote.
The Evil within still has this camera jitter bug, but I fixed it with one workaround.
Disable ingame postAA and force FXAA in driver profile (default disallowed)
Has anyone else noticed the Control Panel isn't picking up nearly as many installed apps/games as it used to? Sure, it opens faster when opening the Programs tab for the first time...that's because it isn't updating.
yeah if u installed the new driver or even the 1st reboot.
after few circles, the apps/games will be appeared but certain apps/games won't appear if u didn't add like e.g battle.net, dota 2, mpc-hc, diablo 3 etc.
My system is behaving much better, after fresh clean install of Win10 then this driver.
Just a heads up as I was scratching my head trying to figure this out. The latest driver for samsung 950 pro 960 pro causes high dpc latency on storport.sys . https://www.guru3d.com/files-details/samsung-nvme-ssd-driver-download.html this is the latest one that doesn't have the issue there is an update for the firmware on samsung magician but the driver update 2.2 or whatever is no good revert to 2.0 if you updated it.
Has anyone gone to the Windows 10 Creators Update with this driver? Are games working?
