> To me, the argument against a proprietary driver seems extremely weak if you're running Windows anyway, but I guess they see it more that if more game devs can run the RADV driver, they can get wider testing (or a simpler story for devs to test at least) and backdoor improvements into the Linux side?

Are you using an AMD driver?

Let me share my experience. One day, you wake up and your GPU driver is gone for no reason. I'm not even joking here—the recent driver update broke the driver for many users. Launch Battlefield 6, and your driver is... gone. A new driver update comes out... Launch Battlefield 6, hard freeze. Improvement. I'm still running an older "blessed" driver version for this reason, and I'm scared to update.

I had an rx 5700xt where one version worked on bf4 but it didn't work on doom eternal. Meanwhile the version had unusable performance when streaming my game to friends. So any time I wanted to play games with friends I had to reinstall an older version. This stayed an issue for months with no communication from AMD.

My current rx6900xt meanwhile has quite a few other stalls and crashes, and doesn't get any of the cool rocm support the 7000series gets.

So my next gpu will be an nvidia. Paying over a thousand euros for a gpu, only to get your support dropped after 2(two!) years of shoddy drivers is just unbearable.

I understood shoddy drivers in the R series, Vega(another lemon i bought) as well, AMD was flat out broke. But by now they surely have some money left over from the ryzen success to make their gpus at least stable.
