massive stutter and input lag when using lossless scaling | Lossless Scaling | Page 1

lossless scaling does not seem to work for upscaling, frame gen, or both at the same time. when any app is scaled this insane stutter/latency happens in it. I took a clip from helldivers where you can see the moment lossless scaling kicks in and how stuttery everything becomes. this happens with any app i try to scale as well as for videos. I have this issue on 2 systems, an n100 mini pc and on my pc with r9 7900x with rx6800xt. I have another pc with r5 5600x3d and 4060ti 16gb and lossless scaling seems to work just fine. settings used in lossless scaling are the same between all pcs

note: i am on driver version 24.7.1 but this issue has been happening since at least 2 driver versions before 24.7.1, although i am not sure exactly when this issue began as i dont regularly use lossless scaling

#

can you share your lossless settings?

#

I don't know much about AMD but we can start from there

#

and Nvidia and AMD settings can be different

#

happens with all scaling types and frame gen types

ripe zinc Jul 25, 2024, 2:25 AM

#

try increasing the frame latency

#

it's an AMD thing

#

it wont increase your latency and even if it does it isn't much

#

maybe this is an AMD problem so idk

#

maybe someone else knows more

#

have a good day

#

happens with amd and intel igpu

ripe zinc Jul 25, 2024, 2:35 AM

#

for intel iGPUs they are kinda slow

#

I have tried it on my system

#

only ever worked with upscaling + framegen

lone gust Jul 25, 2024, 2:37 AM

#

igpu only upscales media and 2d games, gpu performance isnt an issue

lone gust Jul 25, 2024, 2:09 PM

#

anyone able to help?

You have HDR support on lmao

#

that’s why it’s horrible

#

Just turn off the hdr option

#

That’s it

#

nothing else

lone gust Jul 25, 2024, 4:19 PM

#

changed prefered gpu to definately be the graphics card, issue still exists

lone gust Jul 25, 2024, 4:20 PM

#

gray ferry You have HDR support on lmao

When i first used LS hdr support worked and I had no issues with the app. The issue exists with HDR support on and off. turning it off just makes colors ass as well as the performance issue im having

#

this isnt an out-of-the-box issue, when i first used LS everything was fine, this issue was introduced some time later but not sure exactly when. ive been trying to troubleshoot this for like 2 months

lone gust Jul 25, 2024, 4:27 PM

#

ripe zinc try increasing the frame latency

increasing max frame latency makes it worse

gray ferry Jul 25, 2024, 4:41 PM

#

My bad then 🙂

lone gust Jul 26, 2024, 5:50 PM

#

I would appreciate if anyone with more technical knowledge on the app could suggest any troubleshooting steps. I feel as if i wasted my money on a jpeg upscaler because this latency/lag makes everything unusable

ripe zinc Jul 26, 2024, 6:15 PM

#

lone gust increasing max frame latency makes it worse

weird

#

is it on preforamnce?

#

I just need to check I don't remember anything rn

#

usually making max latency 2 or 3 makes it better

#

well idk

#

sorry

lone gust Jul 26, 2024, 6:21 PM

#

theres no difference i can tell between performance modes

#

performance should not be an issue, hardware is powerful enough to run games natively with playable fps without help of upscaling. I use LS for media and software that doesnt come natively in resolutions my monitors are in or for games that dont have built in upscaling/frame gen when i feel like i want to use it

I have the same issue man

lone gust Jul 26, 2024, 6:48 PM

#

is there a log file anywhere generated by LS to try to look into any possible errors happening?

gray ferry Jul 26, 2024, 7:49 PM

#

What is your fps cap at in game?

lone gust Jul 26, 2024, 8:06 PM

#

no fps caps

#

i tried capped and uncapped fps before, it was one of the first things i tried

#

any troubleshooting step you could find in yt videos people mae on howe to use LS, i have tried it all. i been trying to get it working for like 2 months at least now.

gray ferry Jul 26, 2024, 8:13 PM

#

Just so odd. Like your video I recognize and have experienced the same issue

#

But only when my system was extremely cpu overloaded

lone gust Jul 26, 2024, 8:14 PM

#

i strongly suspect it is either a hardware level or driver level issue for my amd and also my intel hardware

gray ferry Jul 26, 2024, 8:14 PM

#

Did you try forcing it to not use e core

lone gust Jul 26, 2024, 8:14 PM

#

amd cpu dont have e core

gray ferry Jul 26, 2024, 8:15 PM

#

affinity bit mask

lone gust Jul 26, 2024, 8:15 PM

#

and the n100 is all e cores

#

doubt it is related to anything cpu

#

this is why im asking if there is anyone with technical knowledge of LS like a dev who can help in support channel, this is more than likely beyond turning a setting on or off that people here are suggesting. if not then this support channel is useless for me no disrespect to you and others for the help you are trying to offer me

gray ferry Jul 26, 2024, 9:54 PM

#

Yeah I get it

@lone gust open CMD as admin

"cd C:\Windows\Microsoft.NET\Framework64\v4.0.30319"
Followed by "ngen update"

Verify file integrity of Lossless scaling from steam after that

Disable every external overlay, including steam and amds, and take a video of the input\output framerates using DXGI and Drawfps. You can have RTSS running if needed

Record the screen itself with a phone

lone gust Jul 27, 2024, 12:49 AM

#

Signed on for a min to check and seems to be working. I'll test more when I'm playing tomorrow. Uninstall and reinstall and also verify integrity did not fix the issue before ngen update btw. I tried that when issue first started

#

@cinder beacon I would try this out since you have same thing happening

olive flint Jul 27, 2024, 1:02 AM

#

Good to hear. Ping me here if you have further issues, otherwise you can close this thread after 2 days

cinder beacon Jul 27, 2024, 6:33 AM

#

lone gust <@324684795479326721> I would try this out since you have same thing happening

its just amd instant replay

#

which is extremley annoing since

#

i use that allot

lone gust Jul 27, 2024, 1:46 PM

#

LS seems to be working except for apps crashing after about 30 min while using 2.2 x2 frame gen. could be an issue with helldivers as its the first game i tried out since applying the fix

#

turning on amd instant replay causes issue to come back but its fine after disabling it again unlike before

#

ill try things on the n100 later
