High GPU usage on shadowplay 3070Ti

[delicate locust]

Please check a monitoring app that also shows clock speed information

Why?

100% load at 300 MHz = 10% at 3000 MHz

GPU usage % do not take into account current speed

Testing right now

with shadowplay disabled ⬇️

do i need to look at Graphics, Memory or Video ?

[somber egret]

anyone knows

Shadowplay has many unresolved issues, thus it is not supported here.

If you are looking for a reliable alternative, please install OBS Studio and read the following guides to configure it:

• NVIDIA NVENC OBS Guide
• Replay Buffer (Instant Replay) guide

[delicate locust]

For better or worse, video recording is not a free action as far as power usage is concerned, if you enabled desktop capture AND instant replay at the same time

especially since you're dealing with 4K

at 60 FPS

that NVENC block basically has to stay on

that said

if you don't need to record videos all the time, OBS is apt

[somber egret]

is obs still a better alternative for now, if i still want to record all the time? using Instant buffer for example(their way of instant replay)

[delicate locust]

Keep in mind that your issue technically isn't one (having a permanently recording function on a 4K desktop)

But pretty much yes

[somber egret]

yea thats what im trying to figure, if thats an issue, but based on your images i sent you, how much MHZ does the recording use? i dont know if i should look on Graphics, Memory or Video and also, if thats considered a big usage, thx

[delicate locust]

Just the Video Engine

[somber egret]

its on ~1400MHz while desktop recording, is that considered alot? im not sure how much it consumes when im running a game

[delicate locust]

For all intents and purposes usage numbers are meaningless at idle

Simply try to record anything and check the results. Does it drop frames?

[somber egret]

i mean yea i could test that but it will take me alot of time to test

[somber egret]

i mean is it really idle when its recording the desktop even?

it still uses 1400MHz of the gpu

[delicate locust]

Try comparing it vs your screen set to 1080p

[somber egret]

it loweres

i tried

its like going from 25% to 2K on 50% and then 4K - 75%

it terms of MHz i assume its also in sync with that

[delicate locust]

Mmm

Basically

GPU can't idle if desktop recording and instant Replay are both on at the same time

Does the GPU go to flat 200-300 MHz if either were disabled?

If so, there's your answer

It stopped being true idle

[somber egret]

instant replay is just desktop recording isnt it?

or instant replay also has some effect on the normal recording

[delicate locust]

No, separate

[delicate locust]

Instant Replay makes it so that the GPU always records the last X minutes, and allows you to save that with a button press, without needing to know when to start recording

Normally, if desktop recording is off, no recording will take place without a 3D app

[somber egret]

yea yea i know

ive been using it for the past 10 yrs or so

i just remember i never had such high usage like a year ago or so

[delicate locust]

If desktop recording was on, I'd think that something funny will happen. I'll check with my desk later

[somber egret]

btw on idle without instant replay recording its -

[delicate locust]

I think you found your answer

Enable both desktop recording and instant Replay, GPU needs to record at all times
