Brave performance are decrease when hardware acceleration is enabled

Hi,

I’m facing an issue with Brave browser, suddenly, few weeks ago, Brave was very slow and it was impossible to use it properly, I though something went wrong with the latest update. But no, I did some research and some people advised me to disable Hardware acceleration. So, I did it and it’s working, but it remains impossible to use it on some website who need 3D acceleration. I’m on a laptop, Win 10 Enterprise, Gfx is a Geforce 2080 MaxQ. Drivers and Brave are updated. No extensions except Ghostery and ADBlock plus. It’s frustrating.

HW acceleration = off, will offload resources from the GPU to the CPU. Meaning, it’ll feel laggy and stutter, performance will hurt with HW acceleration=off.

My Intel UHD GPU was disabled. I did it because it doesn’t work properly with my 4K screen. I have enabled it and brave is working well. Does it mean Brave isn’t properly working with my Nvidia GPU ? At first they was no issue, it suddenly appears one day. My Intel GPU was already disabled.

if you use hardware acceleration, it will use your nvidia or amd gpu cause it has to use the 3d in youtube and video decode when watching live streams

I know it. I’m trying out to understand why Brave isn’t working properly when only my nvidia card is activated. However I force it in the nvidia settings.

@Galex85 it’s because one of your NVIDIA settings is causing your problem. You just have to toy with things to figure out what. To quote myself yet again

There’s no quick answer. Having hardware/graphic acceleration turned on just means it’s using your GPU instead of your CPU for videos and all. Usually this helps increase performance. People who have had issues in the past have shared a variety of things that they found were the cause, such as:

  • Multi-Frame Sampled AA (MFAA) in NVIDIA cards
  • Background Application Max Frame Rate was enabled.
  • Graphics cards needed updated
  • Choose ANGLE graphics backend needed to be changed either in their device graphics settings or toggled at brave://flags
  • Some needed to change brave://flags to enable or disable Vulkan
  • In some scenarios, the issue was because of extensions.
  • Some AMD cards required people to rename Brave as Chrome.exe and issue went away (as they prioritize Chrome for performance)

As you can see, quite a lot of things could be happening.

You’ll want to check your graphics settings on your device. If using NVIDIA, you can do this in NVIDIA Control Panel. Other cards should have something similar. From there you can review and/or change settings on a global or program level.

Then as mentioned in the bullet points, you can try toggling some of the things like Vulkan to see if it helps. Or just change which option was chosen at Choose ANGLE graphics backend (there are 4 choices)

Also check your drivers. Can test in private window and/or new profile if you want to rule out extensions causing the issue.

Sorry, long response…I’ll leave it at that.
