Video Playback Choppy Since Yesterday's Browser Update

@Kaiwen_Du , Use an Internet search engine; search criteria: windows video device driver fps An example of results, note that “DDU was used to completely remove all traces of NVIDIA Drivers” (I have never heard of ‘DDU’): “https://www.reddit.com/r/GlobalOffensive/comments/4xqunx/how_i_fixed_my_fps_after_latest_nvidia_driver/”

FPS - Frames per Second known to be a contributing factor with “laggy” Brave Browser performance:

Brave is very laggy

I hade same issue, brave was super laggy. it was working for months but suddenly changed to super slow/laggy few days ago My solution / fix: Nvidia Control Panel ->3D settings → Manage 3D settings → Global settings → Max Frame rate was 1 fps, i changes that to “off”. After that Brave is fast as it used to be. I have no idea what would changed that to 1fps

Another possible contributing factor – ANGLE graphics backend

Why does Hardware Acceleration Slow Down Brave so much

I found out that if you go to brave://flags and search for ANGLE graphics backend the “Default” setting is what slows down brave so much when you have hardware acceleration enabled. I switched it out to “OpenGL” and a big performance difference. The Default setting that Brave is giving everyone is probably outdated and slowing down many people. Also try D3D11ON12 it also may work better than “OpenGL” experiment with these two values and see which one gives you better results as results may v…

Why does Hardware Acceleration Slow Down Brave so much

flasher777, Details of that flag: Choose the graphics backend for ANGLE. The OpenGL backend is soon to be deprecated on Mac, and may contain driver bugs that are not planned to be fixed. The Metal backend is still experimental, and may contain bugs that are still being worked on. The Metal backend should be more performant, but may still be behind the OpenGL backend until fully released. – Mac Related article [09/24/2018]: “The end of OpenGL and OpenCL on the Mac” at: “https://arstechnica…

Also, there is a Vulkan setting in some [Device Manager] video driver software, and testing that switch, has helped resolve some “Brave Browser laggy” issues.

Thanks for brainstorming but I don’t think this is my issue. It isn’t video that’s a problem since just loading google.com takes about 30 seconds.

I turned off hardware acceleration in settings and that solved the problem
