Brave v1.90.22 LAGGING hard due to D3D11 Hardware Acceleration ANGLE

I am on a reasonably high powered laptop with an RTX A5500 GPU, when I updated to Brave v1.90.22 ~3 days ago it suddenly started lagging to the point where I couldn’t use it (search bar, settings pages, website resolution, everything…).

After:

  1. Clearing Cache

  2. Disabling Extensions

  3. Uninstalling/Reinstalling Brave

  4. Updating Graphics Card Driver

  5. (BINGO) Disable Hardware Acceleration -OR- changing brave://flags/#use-angle from ‘Default’ to D3D9 (default usually is D3D11).

It only worked after #5. but I do NEED my GPU to run specific 3D modeling websites and so D3D9 ANGLE is the only thing that works and am able to keep hardware acceleration going with D3D9. However, I have heard D3D9 is substantially worse, so hoping D3D11 can be resolved.

Anyone else experience this?

At brave://flags “Use D3D12 video encoder” exists:

Thanks, appreciate response here but I’m not sure this will help. I mainly use Hardware Acceleration for navigating online interactive 3D model viewers that use WebGL webapps . So my specific use case is not for watching videos .

My new theory is issue may originate from new Chromium build: Chromium 148.0.7778.167 (main feature of Brave V1.90.22 vs. V1.90.21), fixed security flaws but may have created issues with D3D11 Angle.
