However, Valve notes the fact that enabling hardware acceleration on NVIDIA GPUs may cause X11 to crash. As such, hardware acceleration will be disabled by default for NVIDIA systems. In addition, Valve says that DPI scaling may not work correctly when hardware acceleration is disabled.
What happened to Nvidia open sourcing their graphics driver last year? It seems like nothing came out of it. I know the userland is still closed, but wasn't there an effort to include the driver in Mesa?
I’m not too sure, but I wish there was more action from the code being open sourced. I remember reading a little while back some newer code was leaked for NVIDIA as well, but pretty much the similar issue as there hasn’t been too much done with the info as far as I know.
