We tested the Nvidia App performance problems — games can run up to 15 percent slower with the app

so why do we need this app again?

It's replacing the old Nvidia control panel
- It's replacing GeForce Experience. The nVidia Control Panel is still around.

Damn I'm happy I went AMD.

it is hard if you rely on CUDA and DLSS.
- Damn I’m happy I don’t rely on CUDA or DLSS
- How can you "rely" on DLSS when you can easily use XeSS or FSR?
- ROCM works mostly well in replacement of CUDA, and it gets better and better every year
I went Linux + AMD. No more pesky adwares.
- Same. Never looked back.
- Just works
  Like chocolate and marshmallows
  transcoding, tho...
  Well, almost. Can't have everything.
- Same! It’s a good life.
I thought I was happy I went AMD until my card started overrunning its fans for no reason a month after the warranty ran out. I manually had to reseat the card on the PCIe for it to stop because nothing else would, not even restarting the PC. And then one day it heated up so bad it stopped working. I think they gave me a defective card on purpose because people are less likely to return the items when they're buying from outside the US.
I've since gone back to Nvidia and my current card hasn't given me any issues. What a nightmare that was.
- I swear that in my 20+ years of computer work that everyone has a story like this for every brand out there. It seems to literally be bad luck. That being said some companies just have abysmal and evil support ethics. And these days it seems all of them are trying to dial in the device failure to happen after the warranty expires.

Getting ready to "motivate" people to get the 5xxx series because the current cards "have issues now". The more you buy the more you save!

And the bigger the number on one of the components in the box the funnier the game!
Me nervously eyeing my 5yr old graphic card...

That‘s certainly something they‘re gonna want to fix. I hope DF and GN pick up on this, seems like free views and I‘d love to hear what they‘ve got to say on the matter.

Edit: Also wondering if it‘s the app or if the performance hit disappears when you disable the overlay. Only flew over the article to see what games are affected how badly so mb if that’s mentioned.

Edit 2:

HUB‘s Tim tested it and found that it‘s the overlay or rather the game filter portion of the overlay causing the performance hit. You can disable this part of the overlay in the app‘s settings, or disable the overlay altogether.

He also found that this feature wasn’t impacting performance on GeForce Experience, so it’s very likely a bug that’s gonna be fixed.

To clarify: Using game filters actively can have an impact on either, but right now even when not actively using them, they cause a performance hit just by the functionality being enabled; a bug.

The only outlier where just having the app installed hit performance was the Harry Potter game.

Here's the quote, for people allergic to reading the update in the article.
Update: Nvidia sent us a statement: "We are aware of a reported performance issue related to Game Filters and are actively looking into it. You can turn off Game Filters from the NVIDIA App Settings > Features > Overlay > Game Filters and Photo Mode, and then relaunch your game."
We have tested this and confirmed that disabling the Game Filters and Photo Mode does indeed work. The problem appears to stem from the filters causing a performance loss, even when they're not being actively used. (With GeForce Experience, if you didn't have any game filters enabled, it didn't affect performance.) So, if you're only after the video capture features or game optimizations offered by the Nvidia App, you can get 'normal' performance by disabling the filters and photo modes.
So, TomsHW (is at least claiming that they) did indeed test this, and found that its the filters and photo mode causing the performance hit.
Still a pretty stupid problem to have, considering the old filters did not cause this problem, but at least there's a workaround.
... I'm curious if this new settings app even exists, or has been tested on linux.
Yeah they didn't test that. Nor did they test having the app installed but not running. Crummy article tbh.
- Disagree, and i don’t think it’s the point.
  As an average user, why am I paying a performance hit for nvidia’s own “recommended parameters”
  That’s trash and a terrible experience, and they should be called out for it.
- Modern Tom's hardware
  actually trying
  Not possible.

Let me guess... It uses CFE or Electron?

Yep, uses CEF, though many popular desktop apps do without much perf impact.
- It's not CEF that does most of the impact. It's the contents web devs make it load and process. And web devs generally not being very competent in optimizing is just a sad reality.

Serious question: what is the benefit of Shadowplay now?

I used to use it for all game recording, but Windows Game Bar and Steam have both implemented that functionality now.

Steam recording causes my mouse to stop moving for 1-2 seconds every 5-10 seconds.
- Just out of interest, lower your mouse polling rate to see if it still happens.
  Not an ideal solution obviously.
  I used to have hitching like this.

I already swore off nvidia. My 2080 has been the biggest pain in the ass

How has it been such a pain? I haven’t even thought about my GPU once since I installed it… but I only use regular drivers.

I used to only use this for game recording. But, it got a glitch where games record with a red tint ever since I upgraded my monitor. Thankfully, every single gaming helper app seems to feature recording now, so I just switched to another.

Sounds like something adjusted something in the nvidia control panel and the monitor is balancing that out with a low red value.
Maybe worth to take a look.

I know people complain about Nvidia and Linux but one of the best parts of my experience with it was never having to deal with GFE. Just a bunch of project managers trying to make themselves useful by shovelling needless slop into your GPU driver.

Interesting, as DSOgaming got 4-6% in some games, 0% in others.

Dsogaming has barely ever been a reliable source tbh
