Ubuntu Linux Mint Debian Redhat Youtube Cannot Play HD or 4K videos, dropped frames or high CPU usage with Nvidia or AMD Driver
In a lot of distros, vdpau which accelerates video through the GPUis often not installed even in recent distros. This will result in Firefox with Youtube dropping frames when you check the "Stats for Nerds" and to the eye as jerky or slower video playback due to the dropped frames.
Some sites will say that because you are watching VP09 that there is no GPU support, but with vdpau installed and enabled, many GPUs will still be able to use hardware decoding for 4K........
Nvidia Ubuntu Linux Screentearing Video with solution driver
This seems to happen on most if not all Nvidia cards but the good news is that if you are using any of the Linux drivers and have the nvidia-settings tool installed it is just a simple command.
Solution:
nvidia-settings --assign CurrentMetaMode="nvidia-auto-select +0+0 { ForceFullCompositionPipeline = On }"
Enter the above command in your terminal and the screentearing will be fixed which is like enabling Tear Free on AMD cards.&........
Linux 3D Performance benchmarks with glxgears 59-60fps solution
You need to disable vsync like this when running glxgears:
vblank_mode=0 glxgears
For Nvidia drivers do this:
__GL_SYNC_TO_VBLANK=0 glxgears
Notice the higher than 59-60 fps results with vblank_mode=0:
ATTENTION: default value of option vblank_mode overridden by environment.
7919 frames in 5.0 seconds = 1583.704 FPS
8187 frames in 5.0 seconds = 1637.266 FPS........

I would link to the exact product I am mentioning but it's under Products/5.8Ghz because I can't find the exact URL because of their annoying javascript and frames (you'll see what I mean).
The exciting thing is that this unit can supposedly be up to 72mbit, it is NOT line of sight and the range is up to 20miles. I wonder how real world speeds and range would actually be and if it is reliable.
