Yeah, powersaving increases latency.
When you enable maximum power mode in GPU settings it decreases a lot.
Its why I use normal over saving mode in global and max for individual games.

Did you try running a game in windowed mode in the background?rvteen wrote: ↑22 May 2023, 01:10not useful for me,i tried everythingTiberiusmoon wrote: ↑21 May 2023, 08:27Yeah, powersaving increases latency.

you have very very big latency with your usb controller.sherifmagdy32 wrote: ↑23 May 2023, 20:01I have Firefox opened have multiple tabs and watching twitch streams

Re: Nvidia acknowledged DPC latency issue - help me with your results
They did now? Well but they won't fix it anyways, maybe in 2 years or so, when rolling some new drivers or something... NVCleanInstall from techpowerup (USE DDU in safe mode and made system backup before installing) could help some, although this sounds pretty serious! Also here you have second thread might want to check this out (for running GPU at P0 state, probably want to undervolt for that also if you decide to run it like this 24/7): viewtopic.php?f=10&t=11445. There is utility to switch this on/off, but you need to restart PC I think so it cannot be dynamically used per game etc. https://github.com/auraside/HoneCtrl, also you can enable in bios some 24-119 entries or how it called! Try MSI-X on off, or tweaking related settings, or bios settings! Probably won't help, but it is worth as shot, since who knows what this issue is caused by! And if it is interrupt related, also you can use intel affinity tool and put your GPU maybe to more CPU cores, it won't help probably with lower DPC latency much, could help bit! Don't forget to use ultimate power plan with disable idle saver and 0.5ms timer resolution! Or try different timers Windows uses... These are longshot at best... Also lowering overall DPC latency and disabling C-states, speed-step etc. in BIOS could mitigate overall issues with DPC latency, if you have it from other sources: it can exacerbate problem! You can check my guide for optimizing it in my signature below, all I talk about here in my guide... Overclocking CPU and RAM also can't hurt! And make sure you use GPU scaling override settings of PC games for better fps and consistency (but has slightly higher input lag, but it is worth it)!

Well the mouse is running at 8K pooling rate probably the reasonSlender wrote: ↑24 May 2023, 00:24you have very very big latency with your usb controller.sherifmagdy32 wrote: ↑23 May 2023, 20:01I have Firefox opened have multiple tabs and watching twitch streams

and this is not high it used to be so far worse took me a lot of time
to tweak the system to this level and loving it right now very consistent.
if you have any suggestions that might help feel free to let me know
Re: Nvidia acknowledged DPC latency issue - help me with your results
I believe this has been fixed now a couple driver releases ago?

This is by Savitarax
"figured this would be helpful to anyone who might be in a similar boat.
Nvidia has a bug with their gpu's where if you set the voltage above around 1000mV you can trigger a dpc latency spike of over 150+ microseconds every single time you run a test. This doesn't seem to be an overclocking or instability issue because I can set the frequency stupidly high in relation to how little voltage I am getting and still not get the DPC latency spike so long as I'm not over 1000 mV ish.
Here's a video I made demonstrating it.
