I cannot stream 4k videos through Chrome without severe stuttering. Same goes for streaming 1080 60fps videos. Below is diagnostics of the GPU. Any suggestions would be greatly appreciated. Thanks!
Graphics Feature Status
- Canvas: Hardware accelerated
- Flash: Hardware accelerated
- Flash Stage3D: Hardware accelerated
- Flash Stage3D Baseline profile: Hardware accelerated
- Compositing: Hardware accelerated
- Multiple Raster Threads: Enabled
- Rasterization: Software only. Hardware acceleration disabled
- Video Decode: Hardware accelerated
- Video Encode: Hardware accelerated
- WebGL: Hardware accelerated
Driver Bug Workarounds
- clear_uniforms_before_first_program_use
- disable_d3d11
- exit_on_context_lost
- force_cube_complete
- scalarize_vec_and_mat_constructor_args
- texsubimage_faster_than_teximage
Problems Detected
- Some drivers are unable to reset the D3D device in the GPU process sandbox
Applied Workarounds: exit_on_context_lost - TexSubImage is faster for full uploads on ANGLE
Applied Workarounds: texsubimage_faster_than_teximage - Clear uniforms before first program use on all platforms: 124764, 349137
Applied Workarounds: clear_uniforms_before_first_program_use - Always rewrite vec/mat constructors to be consistent: 398694
Applied Workarounds: scalarize_vec_and_mat_constructor_args - Disable Direct3D11 on systems with AMD switchable graphics: 451420
Applied Workarounds: disable_d3d11 - ANGLE crash on glReadPixels from incomplete cube map texture: 518889
Applied Workarounds: force_cube_complete - Accelerated rasterization has been disabled, either via about:flags or command line.
Disabled Features: rasterization

You can search crbug.com for an existing issue and star it. If you cannot find one, file a new issue using the "New issue" link on the same page.
Please, do not add a "+1" or "Me too" or "Confirmed" (or similar) comment. It just wastes the time of Chrome engineers and sends unnecessary e-mails to all of the people who starred the issue.
You can reply with a link to the found or created issue and might get triaged (and fixed) faster.
Thank you.
